Prospectus Supplement

Prospectus

Neither this prospectus supplement nor the accompanying prospectus is a prospectus for the purposes of the Prospectus Directive (as defined below).

The Notes are not intended to be offered, sold or otherwise made available to, and should not be offered, sold or otherwise made available to, any retail investor in the European Economic Area (“EEA”). For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (“MiFID II”); (ii) a customer within the meaning of Directive 2002/92/EC (“IMD”), where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in the Prospectus Directive. Consequently, no key information document required by Regulation (EU) No 1286/2014 (the “PRIIPs Regulation”) for offering or selling the Notes or otherwise making them available to retail investors in the EEA has been prepared, and

S-i

therefore offering or selling the Notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.

This prospectus supplement and the accompanying prospectus have been prepared on the basis that all offers of the Notes in any Member State of the European Economic Area which has implemented the Prospectus Directive (each, a “Relevant Member State”) will only be made to a legal entity which is a qualified investor under the Prospectus Directive (“Qualified Investors”). Accordingly, any person making or intending to make any offer in that Relevant Member State of Notes which are the subject of the offering contemplated in this prospectus supplement may only do so with respect to Qualified Investors. Neither the Company nor any underwriter has authorized, nor do they authorize, the making of any offer of the Notes other than to Qualified Investors. The expression “Prospectus Directive” means Directive 2003/71/EC (as amended, including by Directive 2010/73/EU), and includes any relevant implementing measure in the Relevant Member State.

The communication of this prospectus supplement, the accompanying prospectus and any other document or materials relating to the issue of any Notes offered hereby is not being made, and such documents and/or materials have not been approved, by an authorized person for the purposes of section 21 of the United Kingdom’s Financial Services and Markets Act 2000. Accordingly, such documents and/or materials are not being distributed to, and must not be passed on to, the general public in the United Kingdom. The communication of such documents and/or materials as a financial promotion is only being made to those persons in the United Kingdom falling within the definition of investment professionals (as defined in Article 19(5) of the Financial Services and Markets Act 2000 (Financial Promotion) Order 2005, as amended (the “Financial Promotion Order”), or within Article 49(2)(a) to (d) of the Financial Promotion Order, or to any other persons to whom it may otherwise lawfully be made under the Financial Promotion Order (all such persons together being referred to as “relevant persons”). In the United Kingdom, the Notes offered hereby are only available to, and any investment or investment activity to which this prospectus supplement relates will be engaged in only with, relevant persons. Any person in the United Kingdom that is not a relevant person should not act or rely on this prospectus supplement or any of its contents.

FORWARD-LOOKING STATEMENTS

This prospectus supplement, including the information incorporated by reference herein, contains forward-looking statements that may be identified by the use of words like “may,” “will,” “could,” “would,” “should,” “expect,” “plan,” “anticipate,” “intend,” “believe,” “estimate,” “project,” “consider,” “predict,” “potential,” “feel” or other comparable terminology. Forward-looking statements reflect our good-faith evaluation of information available at the time the forward-looking statements were made. However, such statements are dependent on and, therefore, can be influenced by a number of external variables over which we have little or no control, including: transportation of hazardous materials as a common carrier by rail; acts of terrorism or war; general economic conditions including, but not limited to, fluctuation and competition within the industries of our customers; competition and consolidation within the transportation industry; the operations of carriers with which we interchange; disruptions to our technology infrastructure, including computer systems; labor difficulties, including strikes and work stoppages; commercial, operating, environmental, and climate change legislative and regulatory developments; results of litigation; natural events such as severe weather, hurricanes, and floods; unpredictable demand for rail services; fluctuation in supplies and prices of key materials, in particular diesel fuel; volatility in energy prices; and changes in securities and capital markets. For a discussion of significant risk factors applicable to us, see Part I, Item 1A, “Risk Factors,” and Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” in the Fiscal 2017 Form 10-K. Forward-looking statements are not, and should not be relied upon as, a guarantee of future performance or results, nor will they necessarily prove to be accurate indications of the times at or by which any such performance or results will be achieved. As a result, actual outcomes and results may differ materially from those expressed in forward-looking statements. We undertake no obligation to update or revise forward-looking statements.

RISK FACTORS

Before making any investment decision, including whether to participate in this offer, you should carefully consider the risk factors below as well as the risk factors discussed in Part I, Item 1A, “Risk Factors,” as well as Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” in the Fiscal 2017 Form 10-K, which is incorporated by reference in this prospectus supplement. See “Incorporation of Certain Documents by Reference.” Based on the information currently known to us, we believe that the foregoing and the following information identifies all known material risk factors relating to the Notes and affecting this offer. However, the risks and uncertainties are not limited to those set forth in the risk factors described above and below. Additional risks and uncertainties not presently known to us or that we currently believe to be less significant than the following risk factors may also adversely affect our business. In addition, past financial performance may not be a reliable indicator of future performance, and historical trends should not be used to anticipate results or trends in future periods. References in this section to “Norfolk Southern,” “we,” “our,” “us” or the “Company” refer to Norfolk Southern Corporation only unless the context otherwise requires.

Risks Relating to the Notes

We may not be able to repurchase the Notes upon a Change of Control Repurchase Event.

Upon the occurrence of a Change of Control Repurchase Event, each holder of Notes will have the right to require us to repurchase all or any part of such holder’s Notes at a price equal to 101% of their principal amount, plus accrued and unpaid interest, if any, to, but not including, the date of repurchase. If we experience a Change of Control Repurchase Event, we cannot assure you that we would have sufficient financial resources available to satisfy our obligations to repurchase the Notes. Furthermore, debt agreements to which we are a party at such time may contain restrictions and provisions limiting our ability to repurchase the Notes, and our ability to repurchase the Notes may also be limited by law. Our failure to repurchase the Notes as required under the indenture governing the Notes would result in a default under such indenture, which could have material adverse consequences to us and the holders of the Notes. See “Description of the Notes—Change of Control Repurchase Event.”

The Change of Control Repurchase Event provision applicable to the Notes provides only limited protection.

The definition of the term “Change of Control Repurchase Event” in the indenture governing the Notes is limited and does not cover a variety of transactions (such as acquisitions by us and recapitalizations or “going private” transactions by our affiliates) that could negatively affect the value of the Notes. A Change of Control under the indenture governing the Notes may only occur if there is a change in the controlling interest in our business. For a Change of Control Repurchase Event to occur, there must be not only a Change of Control as defined in that indenture, but also a ratings downgrade to below investment grade resulting therefrom. If we were to enter into a significant corporate transaction that negatively affects the value of the Notes, but would not result in a Change of Control Repurchase Event, you would not have any rights to require us to repurchase the Notes prior to their maturity and may be required to hold the Notes despite the occurrence of such a transaction, which could materially and adversely affect your investment. See “Description of the Notes—Change of Control Repurchase Event.”

Claims of holders of the Notes will be structurally subordinated to those of creditors and any preferred equity holders of our subsidiaries.

We are a holding company, and we conduct substantially all of our operations through our subsidiaries. We perform management, legal, financial, tax, consulting, administrative and other services for our subsidiaries. Our principal sources of cash are from external financings, dividends and advances from our subsidiaries, investments, payments by our subsidiaries for services rendered, and interest payments from our subsidiaries on

S-4

cash advances. The amount of dividends available to us from our subsidiaries largely depends upon each subsidiary’s earnings and operating capital requirements. The ability of our subsidiaries to make any payments to us will depend upon the terms of any credit facilities or other debt instruments of the subsidiaries, upon the subsidiaries’ earnings, business and tax considerations and legal restrictions.

As a result of our holding company structure, the Notes effectively rank junior to all existing and future debt, trade payables and other liabilities, and preferred equity of our subsidiaries. Our right and the right of our creditors to participate in the assets of any of our subsidiaries upon any liquidation or reorganization of any such subsidiary will be subject to the prior claims of that subsidiary’s creditors, including trade creditors and preferred equity holders, except to the extent that we may ourselves be a creditor of such a subsidiary. As of December 31, 2017, total liabilities (other than intercompany liabilities) of our railroad subsidiaries were approximately $10.2 billion and total debt of our railroad subsidiaries was approximately $605 million.

There is no current public market for the Notes, and a market may not develop.

The Notes are a new issue of securities for which there is currently no trading market. We cannot guarantee:

Liquidity of any market for the Notes and future trading prices of the Notes will depend on many factors, including:

The underwriters have advised us that they currently intend to make a market in the Notes, but they are not obligated to do so and may cease any market-making at any time without notice. In addition, the underwriters’ market-making activities will be subject to limits imposed by the Securities Act of 1933, as amended (the “Securities Act”), and the Exchange Act. It may be difficult for you to find a buyer for the Notes at the time you want to sell them and, even if you find a buyer, you might not receive the price you want.

S-5

USE OF PROCEEDS

Our net proceeds from this offering will be approximately $492.5 million, after deducting the underwriting discount and our estimated offering expenses. We expect to use the net proceeds of this offering for general corporate purposes, including the repayment, in part, of our outstanding 5.75% Senior Notes due 2018, which notes bear interest at a rate of 5.75% per annum and mature on April 1, 2018.

RATIO OF EARNINGS TO FIXED CHARGES

The following table sets forth our ratio of earnings to fixed charges for the periods indicated:

S-7

DESCRIPTION OF THE NOTES

The following description of the Notes we are offering supplements and, to the extent applicable, supersedes the description of the general terms and provisions of our debt securities set forth in the accompanying prospectus under “Description of Debt Securities.” References in this section to “Norfolk Southern,” “we,” “our,” “us” or the “Company” refer to Norfolk Southern Corporation only unless the context otherwise requires.

The Notes will be senior debt issued under an indenture and a supplement thereto to be entered into on the settlement date of this offering (together, the “Indenture”), between Norfolk Southern and U.S. Bank National Association, as trustee (the “Trustee”).

General

The Notes will bear interest at a rate of 4.150% per year. Interest will be payable semi-annually in arrears on February 28 and August 28 of each year, beginning on August 28, 2018 (the “interest payment dates”). Interest on the Notes will be paid to holders of record on the February 14 or August 14, as the case may be, immediately before the interest payment date. If any interest payment date, redemption date or the maturity date falls on a day that is not a Business Day, the required payment shall be made on the next Business Day as if it were made on the date such payment was due, and no interest shall accrue on the amount so payable for the period from and after such interest payment date, redemption date or the maturity date, as the case may be. “Business Day” means any day, other than a Saturday, a Sunday or a day on which banking institutions in The City of New York, New York are authorized or obligated by law, regulation, executive order or governmental decree to close. Interest, principal and any premium will be payable in U.S. dollars at the Trustee’s New York corporate trust office, which is located at 100 Wall Street, Suite 1600, New York, New York 10005. The Notes will mature on February 28, 2048. The Notes will be issued only in denominations of $2,000 and integral multiples of $1,000 in excess thereof. There will be no sinking fund payments for the Notes.

Ranking

The Notes will be our direct, unsecured unsubordinated obligations and will rank equally in right of payment with all of our other existing and future unsecured and unsubordinated indebtedness. As of December 31, 2017, prior to giving effect to the offering of the Notes, we had $9.2 billion of outstanding senior indebtedness (none of which is secured indebtedness) not including the debt of our subsidiaries. Because we are a holding company, the Notes effectively will rank junior to all liabilities and preferred equity of our subsidiaries. See “Risk Factors—Risks Relating to the Notes—Claims of holders of the Notes will be structurally subordinated to those of creditors and any preferred equity holders of our subsidiaries.” As of December 31, 2017, total liabilities (other than intercompany liabilities) of our railroad subsidiaries were approximately $10.2 billion and debt of our railroad subsidiaries was approximately $605 million.

Optional Redemption

The Notes may be redeemed in whole at any time or in part from time to time, at our option, as described below.

If the Notes are redeemed prior to the date that is six months prior to the maturity date for the Notes, the redemption price for the Notes to be redeemed will be equal to the greater of (1) 100% of their principal amount or (2) the sum of the present value of the remaining scheduled payments of principal and interest on the Notes to be redeemed, to and including the date that is six months prior to the maturity date for the Notes (exclusive of interest accrued to, but not including, the date of redemption), discounted to the date of redemption on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the applicable Treasury Yield plus 20 basis points for the Notes, plus accrued and unpaid interest on the principal amount being redeemed to, but not including, the redemption date.

S-8

If the Notes are redeemed on or after the date that is six months prior to the maturity date for the Notes, the redemption price for the Notes to be redeemed will equal 100% of the principal amount of such Notes, plus accrued and unpaid interest to, but not including, the redemption date.

“Treasury Yield” means, with respect to any redemption date, (1) the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15 (519)” or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,” for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after the date that is six months prior to the maturity date for the Notes, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue will be determined and the Treasury Yield will be interpolated or extrapolated from such yields on a straight line basis, rounding to the nearest month) or (2) if such release (or any successor release) is not published during the week preceding the calculation date or does not contain such yields, the rate per annum equal to the semi-annual equivalent yield-to-maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price of such redemption date. The Treasury Yield will be calculated on the third Business Day preceding the redemption date.

“Comparable Treasury Issue” means the United States Treasury security selected by the Independent Investment Banker as having a maturity most comparable to the date that is six months prior to the maturity date for the Notes, that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of a maturity comparable to the remaining term of the Notes.

“Independent Investment Banker” means one of the Reference Treasury Dealers appointed by us.

“Comparable Treasury Price” means, (1) the average of five Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) if the Independent Investment Banker obtains fewer than five such Reference Treasury Dealer Quotations, the average of all such quotations.

“Reference Treasury Dealer” means each of (i) Citigroup Global Markets Inc. and Goldman Sachs & Co. LLC; and (ii) three other primary U.S. Government securities dealers in New York, New York (“Primary Treasury Dealers”) appointed by the Company and their respective successors; provided, however, that if any of the foregoing ceases to be a Primary Treasury Dealer or otherwise fails to provide a Reference Treasury Dealer Quotation, the Company will substitute therefor another Primary Treasury Dealer.

“Reference Treasury Dealer Quotation” means a quotation for a Comparable Treasury Issue provided by a Reference Treasury Dealer.

Change of Control Repurchase Event

If a Change of Control Repurchase Event occurs with respect to the Notes, unless the Company has exercised its right to redeem the Notes as described above, the Company will make an offer to each holder of the Notes to repurchase all or any part (in integral multiples of $1,000) of that holder’s Notes at a repurchase price (the “repurchase price”) in cash equal to 101% of the aggregate principal amount of such Notes repurchased plus any accrued and unpaid interest on the Notes repurchased to, but not including, the repurchase date. Within 30 days following a Change of Control Repurchase Event or, at the Company’s option, prior to a Change of Control, but after the public announcement of such Change of Control, the Company will mail, or cause to be mailed, a notice to each holder of the Notes, with a copy to the Trustee, describing the transaction or transactions that constitute or may constitute the Change of Control Repurchase Event and offering to repurchase the Notes on the

S-9

payment date specified in the notice (such offer the “repurchase offer” and such date the “repurchase date”), which repurchase date will be a Business Day that is no earlier than 30 days and no later than 60 days from the date such notice is mailed. The notice shall, if mailed prior to the date of consummation of the Change of Control, state that the repurchase offer is conditioned on a Change of Control Repurchase Event occurring on or prior to the repurchase date.

The Company will comply with the requirements of Rule 14e-1 under the Exchange Act, and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Repurchase Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Repurchase Event provisions of the Notes, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control Repurchase Event provisions of the Notes by virtue of such conflict.

On the repurchase date following a Change of Control Repurchase Event, the Company will, to the extent lawful:

The Trustee will promptly mail, or cause the paying agent to promptly mail, to each holder of Notes, or portions of Notes, properly tendered the repurchase price for such Notes, or portions of Notes, and the Trustee will promptly authenticate and mail (or cause to be transferred by book-entry) to each holder a new note equal in principal amount to any unpurchased portion of any Notes surrendered, as applicable; provided that each new note will be in a principal amount equal to $2,000 and integral multiples of $1,000 in excess thereof.

The Company will not be required to make a repurchase offer upon a Change of Control Repurchase Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for such an offer made by the Company and such third party purchases all Notes or portions of Notes properly tendered and not withdrawn under its offer.

For purposes of the foregoing discussion of a repurchase at the option of holders, the following definitions are applicable:

“Below Investment Grade Ratings Event” means, with respect to the Notes, on any day within the 60-day period (which period shall be extended so long as the rating of the Notes is under publicly announced consideration for a possible downgrade by any Rating Agency) after the earlier of (1) the occurrence of a Change of Control; or (2) public notice of the occurrence of a Change of Control or the intention by the Company to effect a Change of Control, the Notes are rated below investment grade by each and every Rating Agency. Notwithstanding the foregoing, a Below Investment Grade Ratings Event otherwise arising by virtue of a particular reduction in rating shall not be deemed to have occurred in respect of a particular Change of Control (and thus shall not be deemed a Below Investment Grade Ratings Event for purposes of the definition of Change of Control Repurchase Event hereunder) if the rating agencies making the reduction in rating to which this definition would otherwise apply do not announce or publicly confirm or inform the Trustee in writing at the Company’s request that the reduction was the result, in whole or in part, of any event or circumstance comprised of or arising as a result of, or in respect of, the applicable Change of Control (whether or not the applicable Change of Control shall have occurred at the time of the Below Investment Grade Ratings Event).

S-10

“Change of Control” means the consummation of any transaction (including, without limitation, any merger or consolidation) the result of which is that any “person” or “group” (as those terms are used in Section 13(d)(3) of the Exchange Act), other than the Company or its subsidiaries, becomes the beneficial owner (as defined in Rules 13d-3 and 13d-5 under the Exchange Act), directly or indirectly, of more than 50% of the combined voting power of the Company’s voting stock or other voting stock into which the Company’s voting stock is reclassified, consolidated, exchanged or changed measured by voting power rather than number of shares.

“Change of Control Repurchase Event” means the occurrence of both a Change of Control and a Below Investment Grade Ratings Event with respect to the Notes.

“Investment grade” means, with respect to Moody’s, a rating of Baa3 or better (or its equivalent under any successor rating categories of Moody’s); with respect to S&P, a rating of BBB- or better (or its equivalent under any successor rating categories of S&P); and, with respect to any additional Rating Agency or Rating Agencies selected by the Company, the equivalent investment grade credit rating.

“Moody’s” means Moody’s Investors Service, Inc., a subsidiary of Moody’s Corporation, and its successors.

“Rating Agency” means (1) each of Moody’s and S&P; and (2) if either of Moody’s or S&P ceases to rate the Notes or fails to make a rating of the Notes publicly available for reasons outside of the Company’s control, a “nationally recognized statistical rating organization” as defined in Section 3(a)(62) of the Exchange Act, selected by the Company (as certified by a Board Resolution) as a replacement agency for Moody’s or S&P, or both of them, as the case may be.

“S&P” means S&P Global Ratings, a division of S&P Global Inc., and its successors.

“voting stock” of any specified “person” (as that term is used in Section 13(d)(3) of the Exchange Act) as of any date means the capital stock of such person that is at the time entitled to vote generally in the election of the board of directors of such person.

The Change of Control Repurchase Event provisions of the Notes may in certain circumstances make more difficult or discourage a sale or takeover of the Company and, thus, the removal of incumbent management. We could, in the future, enter into certain transactions, including acquisitions, refinancings or other recapitalizations, that would not constitute a Change of Control Repurchase Event under the Notes, but that could increase the amount of indebtedness outstanding at such time or otherwise affect our capital structure or credit ratings on the Notes.

If we experience a Change of Control Repurchase Event, we may not have sufficient financial resources available to satisfy our obligations to repurchase all Notes or portions of Notes properly tendered. Furthermore, debt agreements to which we are a party at such time may contain restrictions and provisions limiting our ability to repurchase the Notes. Our failure to repurchase the Notes as required under the Indenture would result in a default under the Indenture, which could have material adverse consequences for us and the holders of the Notes.

The definition of the term “Change of Control Repurchase Event” is limited and does not cover a variety of transactions (such as acquisitions by us and recapitalizations or “going private” transactions by our affiliates) that could negatively affect the value of the Notes. A Change of Control may only occur if there is a change in the controlling interest in our business. For a Change of Control Repurchase Event to occur, there must be not only a Change of Control, but also a ratings downgrade to below investment grade resulting therefrom. If we were to enter into a significant corporate transaction that negatively affects the value of the Notes, but would not result in a Change of Control Repurchase Event, you would not have any rights to require us to repurchase the Notes prior to their maturity and may be required to hold the Notes despite the event, which could materially and adversely affect your investment.

S-11

Concerning the Trustee

The holders of a majority, in aggregate principal amount, of the Notes will have the right to direct the time, method and place to conduct any proceeding to exercise any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee with respect to the Notes, subject to certain exceptions. The Indenture provides that if an Event of Default (as defined in the Indenture) occurs (and is not cured) with respect to the Notes, the Trustee will be required, in the exercise of its power, to use the same degree of care and skill a prudent person would use in the conduct of that person’s own affairs. Subject to this standard, the Trustee is not obligated to exercise any of its powers under the Indenture at the request of a holder of Notes, unless the holder offers to indemnify the Trustee against any loss, liability or expense, and then only to the extent required by the terms of the Indenture.

Further Issues

We may from time to time, without notice to or the consent of the registered holders of the Notes, create and issue further notes ranking pari passu with the Notes in all respects (or in all respects except for the issue date, price to public, payment of interest accruing prior to the issue date of such further notes or the first payment of interest following the issue date of such further notes) so that such further notes may be consolidated and form a single series with the Notes and have the same terms as to status, redemption or otherwise as the Notes; provided, however, if such further Notes are not fungible with the original Notes for U.S. federal income tax purposes, such further Notes will have a different CUSIP number than the original Notes and will trade separately from the original Notes.

Governing Law

The Indenture and the Notes will be governed by, and construed in accordance with, the laws of the State of New York, except to the extent the Trust Indenture Act of 1939, as amended, and the regulations promulgated thereunder, shall be applicable.

Book-Entry System

The following are summaries of certain rules and operating procedures of DTC that affect the payment of principal and interest and the transfers of interests in the global notes (the “Global Notes”). Upon issuance, the Notes will be issued only in the form of one or more definitive global securities which will be deposited with, or on behalf of, DTC and registered in the name of Cede & Co., as nominee of DTC. Unless and until it is exchanged in whole or in part for Notes in definitive form under the limited circumstances described below, a Global Note may not be transferred except as a whole (1) by DTC to a nominee, (2) by a nominee of DTC to DTC or another nominee of DTC or (3) by DTC or any such nominee to a successor of DTC or a nominee of such successor.

Ownership of beneficial interests in a Global Note will be limited to persons that have accounts with DTC for such Global Note (“participants”) or persons that may hold interests through participants. Upon the issuance of a Global Note, DTC will credit, on its book-entry registration and transfer system, the participants’ accounts with the respective principal amounts of the Notes represented by such Global Note beneficially owned by such participants. Ownership of beneficial interests in the Global Notes will be shown on, and the transfer of such ownership interests will be effected only through, records maintained by DTC (with respect to interests of participants). The laws of some states may require that certain purchasers of securities take physical delivery of such securities in definitive form. Such laws may limit or impair the ability to own, transfer or pledge beneficial interests in the Global Notes.

So long as DTC or its nominee is the registered owner of a Global Note, DTC or its nominee, as the case may be, will be considered the sole owner or holder of the Notes represented by such Global Note for all

S-12

purposes under the Indenture. Except as set forth below, owners of beneficial interests in a Global Note will not be entitled to have Notes represented by such Global Note registered in their names, will not receive or be entitled to receive physical delivery of such Notes in certificated form and will not be considered the registered owners or holders thereof under the Indenture. Accordingly, each person owning a beneficial interest in a Global Note must rely on the procedures of DTC and, if such person is not a participant, on the procedures of the participant through which such person owns its interest, to exercise any rights of a holder under the Indenture. We understand that under existing industry practices, if we request any action of holders or if an owner of a beneficial interest in a Global Note desires to give or take any action that a holder is entitled to give or take under the Indenture, DTC would authorize the participants holding the relevant beneficial interests to give or take such action, and such participants would authorize beneficial owners owning through such participants to give or to take such action or would otherwise act upon the instructions of beneficial owners holding through them.

Principal and interest payments on interests represented by a Global Note will be made to DTC or its nominee, as the case may be, as the registered owner of such Global Note. None of Norfolk Southern, the Trustee or any other agent of Norfolk Southern or agent of the Trustee will have any responsibility or liability for any facet of the records relating to or payments made on account of beneficial ownership of interests. We expect that DTC, upon receipt of any payment of principal or interest in respect of a Global Note, will immediately credit participants’ accounts with payments in amounts proportionate to their respective beneficial interests in such Global Note as shown on the records of DTC. We also expect that payments by participants to owners of beneficial interests in the Global Notes held through such participants will be governed by standing customer instructions and customary practice, as is now the case with securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of such participants.

If DTC is at any time unwilling or unable to continue as depository for the Notes, and we fail to appoint a successor depository registered as a clearing agency under the Exchange Act within 90 days, we will issue Notes in definitive form in exchange for the respective Global Notes. Any Notes issued in definitive form in exchange for the Global Notes will be registered in such name or names, and will be issued in denominations of $2,000 and integral multiples of $1,000 in excess thereof, as DTC shall instruct the Trustee. It is expected that such instructions will be based upon directions received by DTC from participants with respect to ownership of beneficial interests in the Global Notes.

DTC is a limited purpose trust company organized under the Banking Law of the State of New York, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act. DTC was created to hold the securities of its participants and to facilitate the clearance and settlement of transactions among its participants in such securities through electronic book-entry changes in accounts of the participants, thereby eliminating the need for physical movement of securities certificates. DTC’s participants include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations, some of which (and/or their representatives) own DTC. Access to the DTC book-entry system is also available to others, such as banks, brokers and dealers and trust companies that clear through or maintain a custodial relationship with a participant, either directly or indirectly.

Same-Day Settlement and Payment

Settlement for the Notes will be made by the underwriters in immediately available funds. All payments of principal and interest in respect of the Notes will be made by us in immediately available funds.

The Notes will trade in DTC’s Same-Day Funds Settlement System until maturity and secondary market trading activity in the Notes will settle in immediately available funds. No assurance can be given as to the effect, if any, of settlement in immediately available funds on trading activity in the Notes.

U.S. FEDERAL INCOME TAX CONSIDERATIONS FOR NON-U.S. HOLDERS

The following discussion is a summary of United States federal income tax considerations generally applicable to the ownership and disposition of the Notes by a Non-U.S. Holder (as defined below). This discussion does not address specific tax consequences that may be relevant to particular persons in light of their individual circumstances (including, for example, entities treated as partnerships for United States federal income tax purposes or partners or members therein, banks or other financial institutions, broker-dealers, insurance companies, regulated investment companies, tax-exempt entities, common trust funds, certain expatriates, controlled foreign corporations, dealers in securities or currencies, accrual method taxpayers subject to special tax accounting rules as a result of their use of financial statements, and persons in special situations, such as those who hold the Notes as part of a straddle, hedge, synthetic security, conversion transaction or other integrated investment comprised of the Notes and one or more other investments). Unless otherwise stated, this discussion is limited to Non-U.S. Holders that purchase the Notes in this offering at their issue price and that hold such Notes as capital assets for United States federal income tax purposes. In addition, this discussion does not describe any tax consequences arising under United States federal gift and estate tax or other U.S. federal tax laws or under the tax laws of any state, local or foreign jurisdiction. This discussion is based upon the Internal Revenue Code of 1986, as amended (the “Code”), the Treasury Regulations (the “Treasury Regulations”) promulgated thereunder, and administrative and judicial interpretations thereof, all as of the date hereof and all of which are subject to change, possibly with retroactive effect.

Prospective purchasers of the Notes are urged to consult their tax advisors concerning the United States federal income tax consequences to them of acquiring, owning and disposing of the Notes, as well as the application of state, local and foreign income and other tax laws.

For purposes of this discussion, a Non-U.S. Holder is a beneficial owner of the Notes other than a partnership (or entity treated as a partnership for United States federal income tax purposes) that is not a U.S. person. A “U.S. person” means (i) a citizen or individual resident of the United States; (ii) a corporation (including an entity treated as a corporation for United States federal income tax purposes) created or organized in or under the laws of the United States, any state thereof or the District of Columbia; (iii) an estate, the income of which is subject to United States federal income tax regardless of the source; or (iv) a trust, if a court within the United States is able to exercise primary supervision over the trust’s administration and one or more U.S. persons have the authority to control all its substantial decisions.

Payments of Interest. Subject to the discussion under “Information Reporting and Backup Withholding” and “Foreign Account Tax Compliance Act,” payments of interest on the Notes made by us or our agent to a Non-U.S. Holder generally will not be subject to United States federal withholding tax, provided that:

S-14

If a Non-U.S. Holder cannot satisfy the requirements of the exemption described above, payments of interest made to such Non-U.S. Holder will be subject to a 30% withholding tax unless the beneficial owner of the Notes provides the applicable withholding agent with a properly executed:

If interest on the Notes is effectively connected with the conduct of a U.S. trade or business of the beneficial owner (and, if certain tax treaties apply, is attributable to a permanent establishment maintained by the Non-U.S. Holder within the United States), the Non-U.S. Holder, although exempt from the withholding tax described above, will generally be subject to United States federal income tax on the receipt or accrual of such interest on a net income basis in the same manner as if it were a U.S. person. In addition, if such Non-U.S. Holder is a foreign corporation, it may be subject to a branch profits tax equal to 30% (or lower applicable treaty rate) of its effectively connected earnings and profits for the taxable year, subject to adjustments. For this purpose, interest on the Notes will be included in such foreign corporation’s earnings and profits.

Disposition of the Notes. Subject to the discussion under “Foreign Account Tax Compliance Act” below, no withholding of United States federal income tax generally will be required with respect to any gain realized by a Non-U.S. Holder upon the sale, exchange or other taxable disposition of the Notes.

In addition, a Non-U.S. Holder will not be subject to United States federal income tax on gain realized on the sale, exchange or other taxable disposition of the Notes unless (i) the Non-U.S. Holder is an individual who is present in the United States for a period or periods aggregating 183 or more days in the taxable year of the disposition and certain other conditions are met, or (ii) such gain is effectively connected with the Non-U.S. Holder’s U.S. trade or business and, if certain tax treaties apply, is attributable to a permanent establishment maintained by the Non-U.S. Holder within the United States.

Information Reporting and Backup Withholding

In general, backup withholding and information reporting will not apply to a payment of interest on a Note to a Non-U.S. Holder, or to proceeds from the disposition of a Note by a Non-U.S. Holder, in each case, if the holder certifies under penalties of perjury that it is a Non-U.S. Holder and the applicable withholding agent does not have actual knowledge or reason to know to the contrary. Any amounts withheld under the backup withholding rules will be refunded or credited against the Non-U.S. Holder’s United States federal income tax liability provided the required information is timely furnished to the IRS. In certain circumstances, if a Note is not held through a qualified intermediary, the amount of payments made on such Note, the name and address of the beneficial owner and the amount, if any, of tax withheld may be reported to the IRS.

Foreign Account Tax Compliance Act

Sections 1471 through 1474 of the Code and the Treasury regulations promulgated thereunder (commonly referred as the “Foreign Account Tax Compliance Act” or “FATCA”) generally impose withholding at a rate of 30% in certain circumstances on (i) interest payable on, and (ii) after December 31, 2018, gross proceeds from the disposition of, the Notes held by or through certain financial institutions (including investment funds), unless such institution certifies that it has entered into, and complies with, an agreement with the IRS to report, on an annual basis, information with respect to certain interests in, and accounts maintained by, the institution that are owned by certain U.S. persons or by certain non-U.S. entities that are wholly or partially owned by U.S. persons and to withhold on certain payments. Similarly, (i) interest payable on, and (ii) after December 31, 2018, gross proceeds from the disposition of, the Notes held by an investor that is a non-financial non-U.S. entity that does

S-15

not qualify under certain exemptions generally will be subject to withholding at a rate of 30%, unless such entity either (y) certifies that such entity does not have any “substantial United States owners” or (z) provides certain information regarding the entity’s “substantial United States owners,” which will in turn be provided to the United States Department of the Treasury. An intergovernmental agreement between the United States and an applicable foreign country may modify these requirements. Prospective investors should consult their tax advisors regarding the possible implications of these rules on an investment in the Notes.

S-16

UNDERWRITING

Under the terms and subject to the conditions contained in the underwriting agreement dated the date of this prospectus supplement, the underwriters named below, for whom Citigroup Global Markets Inc. and Goldman Sachs & Co. LLC are acting as representatives, have severally agreed to purchase, and we have agreed to sell to them, severally, the respective principal amount of the Notes set forth opposite their names below:

The underwriting agreement provides that the obligations of the underwriters to pay for and accept delivery of the Notes offered hereby are subject to the approval of certain legal matters by their counsel and to certain other conditions. The underwriters are obligated to take and pay for all of the Notes if any Notes are taken. The offering of the Notes by the underwriters is subject to receipt and acceptance and subject to the underwriters’ right to reject any order in whole or in part.

The underwriters have advised us that they propose initially to offer the Notes to the public at the public offering price on the cover page of this prospectus supplement, and to dealers at that price less a concession not in excess of 0.525% of the principal amount of the Notes. The underwriters may allow, and the dealers may reallow, a discount not in excess of 0.250% of the principal amount of the Notes to other dealers. After the Notes are released to the public, the offering price and other selling terms may from time to time be varied by the underwriters.

The expenses of the offering payable by us, not including the underwriting discount, are estimated to be $850,000.

We have agreed to indemnify the several underwriters against certain liabilities, including liabilities under the Securities Act, or to contribute to payments that the underwriters may be required to make in respect of those liabilities.

In order to facilitate the offering of these securities, the underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the Notes or any other notes the prices of which may be used to determine payments on the Notes. Specifically, the underwriters may sell more Notes than they are obligated to purchase in connection with the offering, creating a short position for their own accounts. A short sale is covered by purchasing the Notes in the open market. A short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the Notes in the open market after pricing that could adversely affect investors who purchase in the offering. As an additional means of facilitating the offering, the underwriters may bid for, and purchase, the Notes or any other notes in the open market to stabilize the price of the Notes or of any other notes. Finally, in any offering of the Notes through a syndicate of underwriters or dealer group, the underwriters acting on behalf of the underwriting syndicate or for themselves may impose a penalty bid, whereby the underwriters reclaim selling concessions allowed to an underwriter or a dealer for distributing the Notes in the offering, if the underwriters repurchase previously distributed Notes to cover syndicate short positions or to stabilize the price of the Notes. Any of these activities may raise or maintain the market price of the Notes above independent market levels or prevent or retard a decline in the market price of the Notes. The underwriters are not required to engage in these activities, and may end any of these activities at any time without notice.

S-17

In general, purchases of a Note for the purpose of stabilizing or reducing a syndicate short position could cause the price of the Note to be higher than it might otherwise be in the absence of such purchases without notice.

Neither we nor the underwriters make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the Notes.

The underwriters and their affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, financing and brokerage activities. Each of the underwriters and/or its affiliates may have performed certain investment banking, commercial banking and advisory services for us from time to time for which they have received customary fees and expenses. Certain of the underwriters and/or their affiliates are lenders under our existing unsecured revolving credit facility. The underwriters may, from time to time, engage in transactions with and perform services for us in the ordinary course of their business for which they will receive customary fees and expenses. In the ordinary course of their various business activities, the underwriters and their affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own accounts and for the accounts of their customers, and such investment and securities activities may involve securities and/or instruments of the Company. If any of the underwriters or their affiliates have a lending relationship with us, certain of those underwriters and their affiliates routinely hedge, and certain other of those underwriters or their affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, such underwriters and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the Notes. Any such credit default swaps or short positions could adversely affect future trading prices of the Notes offered hereby. The underwriters and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or instruments and may at any time hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

U.S. Bancorp Investments, Inc., one of the underwriters, is an affiliate of the Trustee.

It is expected that delivery of the Notes will be made against payment therefor on or about the date specified on the cover page of this prospectus supplement, which will be the tenth business day following the date of pricing of the Notes (such settlement cycle being referred to herein as “T+10”). Under Rule 15c6-1 under the Exchange Act, trades in the secondary market generally are required to settle in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Notes on the date of pricing or the next seven business days will be required, by virtue of the fact that the Notes initially will settle in T+10, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of Notes who wish to trade the Notes on the date of pricing or the next seven business days should consult their own advisor.

Selling Restrictions

DESCRIPTION OF SECURITIES

This prospectus contains summary descriptions of the debt securities, common stock, preferred stock, warrants, depositary shares, stock purchase contracts and stock purchase units that we may offer and sell from time to time. These summary descriptions are not meant to be complete descriptions of each security. However, at the time of an offering and sale, this prospectus together with the accompanying prospectus supplement will contain the material terms of the securities being offered.

DESCRIPTION OF DEBT SECURITIES

As used in this prospectus, debt securities means the debentures, notes, bonds and other evidences of indebtedness that we may issue separately, upon exercise of a debt warrant, in connection with a stock purchase contract or as part of a stock purchase unit from time to time. The debt securities may either be senior debt securities or subordinated debt securities. Senior debt securities may be issued under a “Senior Indenture” and subordinated debt securities may be issued under a “Subordinated Indenture.” This prospectus sometimes refers to the Senior Indenture and the Subordinated Indenture collectively as the “Indentures.” The Indentures have been filed with the SEC as exhibits to the registration statement on Form S-3 of which this prospectus forms a part. We may also issue debt securities under a separate, new indenture. If that occurs, we will describe any differences in the terms of any series or issue of debt securities in the prospectus supplement relating to that series or issue.

The following briefly summarizes the material provisions of the Indentures and the debt securities, other than pricing and related terms disclosed in the accompanying prospectus supplement or pricing supplement, as the case may be. You should read the more detailed provisions of the applicable Indenture, including the defined terms, for provisions that may be important to you. You should also read the particular terms of an offering of debt securities, which will be described in more detail in the applicable prospectus supplement or pricing supplement, as the case may be. Copies of the Indentures may be obtained from Norfolk Southern Corporation or the applicable trustee.

As used in this “Description of Debt Securities,” the terms “Norfolk Southern,” “we,” “our,” “us” and the “company” refer to Norfolk Southern Corporation, a Virginia corporation, and do not, unless otherwise specified, include our subsidiaries.

General

The debt securities will be our direct unsecured obligations. The senior debt securities will rank equally with all of our other senior unsecured and unsubordinated indebtedness. The subordinated debt securities will be subordinate and junior in right of payment to all of our present and future senior indebtedness to the extent and in the manner set forth in the Subordinated Indenture.

Since our operations are partially conducted through our subsidiaries, the cash flow and the consequent ability to service our indebtedness, including the debt securities, is partially dependent upon the earnings of our subsidiaries and the distribution of those earnings or upon advances or other payments of funds by those subsidiaries to us. Our subsidiaries are separate and distinct legal entities and have no obligation, contingent or otherwise, to pay any amounts due pursuant to the debt securities or to make funds available to us, whether by dividends, loans or other payments. In addition, the payment of dividends and the making of loans and advances to us by our subsidiaries may be subject to contractual or statutory restrictions, are contingent upon the earnings of those subsidiaries and are subject to various business considerations. Any right we may have to receive assets of any of our subsidiaries upon their liquidation or reorganization (and the consequent right of the holders of our debt securities to participate in those assets) will be effectively subordinated to the claims of such subsidiary’s creditors, including trade creditors.

6

The Indentures do not limit the aggregate principal amount of debt securities that we may issue and provide that we may issue debt securities from time to time in one or more series, in each case with the same or various maturities, at par or at a discount. We may issue additional debt securities of a particular series without the consent of the holders of the debt securities of such series outstanding at the time of the issuance. Any such additional debt securities, together with all other outstanding debt securities of that series, will constitute a single series of debt securities under the applicable Indenture. The Indentures also do not limit our ability to incur other debt.

Each prospectus supplement will summarize the material terms relating to the specific series of debt securities being offered. These terms may include some or all of the following:

7

Unless otherwise specified in the applicable prospectus supplement, the debt securities will not be listed on any securities exchange and will be issued in fully-registered form without coupons.

Debt securities may be sold at a substantial discount below their stated principal amount, bearing no interest or interest at a rate which at the time of issuance is below market rates. The applicable prospectus supplement will describe the federal income tax consequences and special considerations applicable to any such debt securities. The debt securities may also be issued as indexed securities or securities denominated in foreign currencies, currency units or composite currencies, as described in more detail in the prospectus supplement relating to any of the particular debt securities. The prospectus supplement relating to specific debt securities will also describe any special considerations and certain additional tax considerations applicable to such debt securities.

Subordination

The prospectus supplement relating to any offering of subordinated debt securities will describe the specific subordination provisions, including the extent of subordination of payments by us of the principal of (and premium, if any) and interest on such subordinated debt securities.

The Subordinated Indenture does not limit the issuance of additional senior debt securities.

Limitations on Liens

We will not, and will not permit any of our Subsidiaries to, create, assume, incur or suffer to exist any mortgage, pledge, lien, encumbrance, charge or security interest of any kind, other than a Purchase Money Lien, upon any stock or indebtedness, owned on the date any debt securities are first issued or thereafter acquired, of the Principal Subsidiary, to secure any Obligation (other than the debt securities) of the company, any Subsidiary or any other Person, without in any such case making effective provision whereby all of the outstanding debt securities are secured equally and ratably with such Obligation.

8

Such limitation will not apply to any mortgage, pledge, lien, encumbrance, charge or security interest on any stock or indebtedness of a corporation existing at the time such corporation becomes a Subsidiary. Such limitation will not restrict any of our other property or other property of our Subsidiaries or restrict the sale by us or any Subsidiary of any stock or indebtedness of any Subsidiary.

Limitations on Funded Debt

The Indentures provide that we will not permit any Restricted Subsidiary to incur, issue, guarantee or create any Funded Debt unless, after giving effect thereto, the sum of the aggregate amount of all outstanding Funded Debt of the Restricted Subsidiaries would not exceed an amount equal to 15% of Consolidated Net Tangible Assets.

The limitation on Funded Debt will not apply to, and there will be excluded from Funded Debt in any computation under such restriction, Funded Debt secured by:

Consolidation, Merger and Sale of Assets

So long as any debt securities are outstanding, we cannot consolidate with or merge into any other Person, or sell, assign, transfer, convey, lease or otherwise dispose of all, or substantially all, of our assets, in one or more related transactions, to any Person, unless:

Since we are a holding company, if one of our Subsidiaries distributes its assets as a result of a liquidation or recapitalization of that subsidiary, our rights, and indirectly the rights of our creditors and of the holders of debt securities to participate in such Subsidiary’s distribution of assets will be subject to the prior claims of such Subsidiary’s creditors, except to the extent that we may be a creditor with prior claims enforceable against such Subsidiary.

Events of Default

Under the Indentures, the following are “Events of Default”:

12

If an Event of Default occurs and is continuing, either the trustee or the holders of at least 25% in aggregate principal amount of the outstanding debt securities of a particular series, may notify Norfolk Southern (and the trustee, if notice is given by the holders) and declare that the unpaid principal of (premium, if any) and accrued interest on, if any, the debt securities of such series is due and payable immediately. However, under certain circumstances, the holders of a majority in aggregate principal amount of outstanding debt securities of such series may be able to rescind and annul this declaration for accelerated payment. Norfolk Southern will furnish the trustee with an annual statement that describes how Norfolk Southern has performed its obligations under the applicable Indenture, and that specifies any defaults that may have occurred.

Discharge, Defeasance and Covenant Defeasance

Unless otherwise provided in an applicable Indenture supplement, we may discharge certain obligations to holders of any debt securities issued under the Indenture of a particular series when:

and if, in either case, we have paid or caused to be paid all other sums payable by us under the Indenture with respect to the debt securities of that series and we have delivered to the trustee an officers’ certificate and an opinion of counsel each stating that the requisite conditions precedent have been complied with.

In addition, unless otherwise provided in an applicable Indenture supplement, we may elect with respect to any series of debt securities either:

13

We may exercise our defeasance option or our covenant defeasance option with respect to any series of debt securities, only if:

Absent a change in federal tax laws, a defeasance is likely to be treated as a taxable exchange by holders of the relevant debt securities for an issue consisting of either obligations of the trust or a direct interest in the cash and securities held in the trust, with the result that such holders would be required for tax purposes to recognize gain or loss as if such obligations or the cash or securities deposited, as the case may be, had actually been received by them in exchange for their debt securities. In addition, if the holders are treated as the owners of their proportionate share of the cash or securities held in trust, such holders would then be required to include in their income for tax purposes any income, gain or loss attributable thereto even though no cash was actually received. Thus, such holders might be required to recognize income for tax purposes in different amounts and at different times than would be recognized in the absence of defeasance. Prospective investors are urged to consult their own tax advisors as to the specific consequences of defeasance.

Modification and Waiver

Modification and amendments of the Indentures may be made by us and the trustee with the consent of the holders of not less than a majority in aggregate principal amount of the outstanding debt securities of each series affected thereby; provided, however, that no such modification or amendment may, without the consent of the holder of each outstanding debt security of a particular series affected thereby:

The holders of not less than a majority in principal amount of the debt securities of a series affected thereby, on behalf of all of the holders of the debt securities of such series, are permitted to waive any past default under the applicable Indenture with respect to the debt securities of such series, and its consequences, except a default

14

in the payment of the principal of (or premium, if any) or interest on any debt security or a default in respect of a covenant or provision of the applicable Indenture which cannot be modified or amended without the consent of the holder of each debt security affected. Any such consent or waiver by the holder of a debt security shall be binding upon such holder and upon every subsequent holder of such security, irrespective of whether or not any notation of such consent or waiver is made upon such debt security, unless revoked as provided in the applicable Indenture.

Payment and Paying Agents

The Indentures provide that payment of interest on a debt security on any interest payment date will be made to the Person in whose name a debt security is registered at the close of business on the record date for the interest.

Holders must surrender debt securities to a paying agent to collect principal payments. Unless specified otherwise in the applicable prospectus supplement or pricing supplement, we will pay principal and interest in money of the United States of America that at the time of payment is legal tender for payment of public and private debts. Payments in respect of the securities represented by a global security (including principal (and premium, if any) and interest) will be made by wire transfer of immediately available funds to the accounts specified by the depository, which shall be The Depository Trust Company, or DTC, its nominees and their respective successors.

The Indentures provide that initially, U.S. Bank National Association, a national banking association, will act as paying agent and registrar. We may appoint and change any paying agent, registrar or co-registrar without notice. We or any of our domestically incorporated wholly owned subsidiaries may act as paying agent, registrar or co-registrar.

We will maintain an office or agency in the City of New York where debt securities may be presented for registration of transfer or for exchange and an office or agency in the City of New York where debt securities may be presented for payment. The registrar shall keep a register of the debt securities and of their transfer and exchange. We may have one or more co-registrars and one or more additional paying agents.

If money for the payment of principal, premium, if any, or interest remains unclaimed for two years after such amount has become due and payable, the trustee or paying agent shall pay the money back to us at our written request unless an abandoned property law designates another person. After any such payment, holders entitled to the money must look only to us and not to the trustee or paying agent for payment.

Denominations, Registrations and Transfer

Unless an accompanying prospectus supplement states otherwise, debt securities will be represented by one or more global certificates registered in the name of a nominee for DTC. In such case, each holder’s beneficial interest in the global securities will be shown on the records of DTC and transfers of beneficial interests will only be effected through DTC’s records.

A holder of debt securities may only exchange a beneficial interest in a global security for certificated securities registered in the holder’s name if:

If debt securities are issued in certificated form, they will only be issued in the minimum denomination specified in the accompanying prospectus supplement and integral multiples of such denomination. Transfers and

15

exchanges of such debt securities will only be permitted in such minimum denomination. Transfers of debt securities in certificated form may be registered at the trustee’s corporate office or at the offices of any paying agent or trustee appointed by us under the Indentures. Exchanges of debt securities for an equal aggregate principal amount of debt securities in different denominations may also be made at such locations.

Governing Law

The Indentures are and the debt securities will be governed by, and construed in accordance with, the internal laws of the State of New York, except to the extent the Trust Indenture Act of 1939, as amended, and the regulations promulgated thereunder, shall be applicable.

Regarding the Trustee

The trustee of the Indentures is U.S. Bank National Association. The trustee in its individual or any other capacity may become the owner or pledgee of debt securities and may otherwise deal with us or our affiliates with the same rights it would have if it were not trustee.

DESCRIPTION OF CAPITAL STOCK

General

The following summary of our common stock and preferred stock is not meant to be a complete description. For more information, you also should refer to our Restated Articles of Incorporation (the “Articles of Incorporation”), our Bylaws (the “Bylaws”) and the Virginia Stock Corporation Act (the “Virginia Act”). Under the Articles of Incorporation, our authorized capital stock consists of 1,350,000,000 shares of common stock, par value $1.00 per share, and 25,000,000 shares of preferred stock, without par value. We will describe the specific terms of any common stock or preferred stock we may offer in a prospectus supplement. The specific terms we describe in a prospectus supplement may differ from the terms we describe below.

Common Stock

As of January 31, 2018, Norfolk Southern had 283,997,242 shares of common stock issued and outstanding, excluding 20,320,777 shares held by our wholly owned subsidiaries. For all matters submitted to a vote of stockholders, each holder of common stock is entitled to one vote for each share registered in his or her name on our books. Our common stock does not have cumulative voting rights. As a result, subject to the voting rights of any outstanding preferred stock (of which there currently is none), the persons who hold a majority of the outstanding common stock entitled to elect members of the board of directors (the “Board”) can elect all of the directors of the company.

If the Board declares a dividend, common stockholders will receive payments from the funds of Norfolk Southern that are legally available to pay dividends. However, this dividend right is subject to any preferential dividend rights we may grant to the persons who hold preferred stock, if any is issued. If Norfolk Southern is dissolved, the holders of common stock will be entitled to share ratably in all the assets that remain after we pay (i) our liabilities and (ii) any amounts we may owe to the persons who hold our preferred stock, if any is issued. Common stockholders do not have preemptive rights, and they have no right to convert their common stock into any other securities. All outstanding shares of common stock are duly authorized, validly issued, fully paid and nonassessable.

The transfer agent and registrar for our common stock is American Stock Transfer and Trust Company.

Preferred Stock

No shares of preferred stock are issued or outstanding. However, 600,000 shares of preferred stock designated as “Series A Junior Participating Preferred Stock” are authorized by our Articles of Incorporation, which further authorize the Board to issue preferred stock in one or more series and to determine the liquidation preferences, voting rights, dividend rights, conversion rights and redemption rights of each such series. The ability of the Board to issue and set the terms of preferred stock could make it more difficult for a third person to acquire control of Norfolk Southern. The Board has the authority to fix the following terms of any series of preferred stock, each of which will be set forth in the related prospectus supplement:

17

Norfolk Southern will designate the transfer agent and registrar for each series of preferred stock in a prospectus supplement.

Certain Provisions of the Virginia Stock Corporation Act

The Virginia Act contains certain anti-takeover provisions regarding, among other things, affiliated transactions and control share acquisitions. In general, the Virginia Act’s affiliated transactions provisions prevent a Virginia corporation from engaging in an “affiliated transaction” (as defined in the Virginia Act) with an “interested shareholder” (generally defined as a person owning more than 10% of any class of voting securities of the corporation) unless approved by a majority of the “disinterested directors” (as defined in the Virginia Act) and the holders of at least two thirds of the outstanding voting stock not owned by the interested shareholder, subject to certain exceptions.

Under the control share acquisitions provisions of the Virginia Act, shares acquired in a “control share acquisition,” generally defined as transactions that increase the voting strength of the person acquiring such shares above certain thresholds in elections of directors generally, have no voting rights unless they are granted by a majority of the outstanding voting stock not owned by such acquiring person, by an officer of Norfolk Southern or by an employee-director of Norfolk Southern. If such voting rights are granted and the acquiring person controls 50% or more of the voting power, all shareholders, other than the acquiring person, are entitled to receive “fair value” (as defined in the Virginia Act) for their shares. If such voting rights are not granted, the corporation may, if authorized by its articles of incorporation or bylaws, purchase the acquiring person’s shares at their cost to the acquiring person. A Virginia corporation has the right to “opt out” of the control share acquisition statute, and effective January 27, 2009, the Board amended our bylaws to “opt out” of the statute.

18

DESCRIPTION OF WARRANTS

This section describes the general terms and provisions of our warrants to acquire our securities that we may issue from time to time. The applicable prospectus supplement will describe the terms of any warrant agreements and the warrants issuable thereunder. If any particular terms of the warrants described in the prospectus supplement differ from any of the terms described herein, then the terms described herein will be deemed superseded by that prospectus supplement.

We may issue warrants for the purchase of our debt securities, common stock, preferred stock, depositary shares or securities of third parties or other rights, including rights to receive payment in cash or securities based on the value, rate or price of one or more specified commodities, currencies, securities or indices, or any combination of the foregoing. We may issue warrants independently or together with other securities, and they may be attached to or separate from the other securities. Each series of warrants will be issued under a separate warrant agreement that we will enter into with a bank or trust company, as warrant agent, as detailed in the applicable prospectus supplement. The warrant agent will act solely as our agent in connection with the warrants and will not assume any obligation, or agency or trust relationship, with you. We will file a copy of the warrant and warrant agreement with the SEC each time we issue a series of warrants, and these warrants and warrant agreements will be incorporated by reference into the registration statement of which this prospectus is a part. A holder of our warrants should refer to the provisions of the applicable warrant agreement and prospectus supplement for more specific information.

The prospectus supplement relating to a particular issue of warrants will describe the terms of those warrants, including, when applicable:

After your warrants expire they will become void. All warrants will be issued in registered form. The prospectus supplement may provide for the adjustment of the exercise price of the warrants.

19

Warrants may be exercised at the appropriate office of the warrant agent or any other office indicated in the applicable prospectus supplement. Before the exercise of warrants, holders will not have any of the rights of holders of the securities purchasable upon exercise and will not be entitled to payments made to holders of those securities.

The applicable warrant agreement may be amended or supplemented without the consent of the holders of the warrants to which it applies to effect changes that are not inconsistent with the provisions of the warrants and that do not materially and adversely affect the interests of the holders of the warrants. However, any amendment that materially and adversely alters the rights of the holders of warrants will not be effective unless the holders of at least a majority of the applicable warrants then outstanding approve the amendment. Every holder of an outstanding warrant at the time any amendment becomes effective, by continuing to hold the warrant, will be bound by the applicable warrant agreement as amended. The prospectus supplement applicable to a particular series of warrants may provide that certain provisions of the warrants, including the securities for which they may be exercisable, the exercise price and the expiration date, may not be altered without the consent of the holder of each warrant.

20

DESCRIPTION OF DEPOSITARY SHARES

Norfolk Southern may elect to offer fractional shares of preferred stock rather than full shares of preferred stock. If so, Norfolk Southern will issue receipts for these “depositary shares,” each of which will represent a fraction of a share of a particular series of preferred stock. Each holder of a depositary share will be entitled, in proportion to the fraction of preferred stock represented by that depositary share, to the rights and preferences of the preferred stock, including any dividend, voting, redemption, conversion and liquidation rights. Norfolk Southern will enter into an agreement (the “Deposit Agreement”) with a depositary, which will be named in the related prospectus supplement, and with the holders of the “depositary receipts” that represent the depositary shares.

The following summary of the depositary shares is not meant to be complete. For more information, you should refer to the Deposit Agreement, to the depositary receipts and the certificate of designation of the series of preferred stock that underlies that series of depositary shares and to the related prospectus supplement. A form of Deposit Agreement, depositary receipt and certificate of designation will be filed as exhibits to, or incorporated by reference into, the registration statement before we issue depositary receipts.

General

In order to issue depositary shares, Norfolk Southern will issue preferred stock, and immediately deposit these shares with the depositary. The depositary then will issue and deliver depositary receipts to the persons who purchase depositary shares. The depositary will issue depositary receipts in a form that reflects whole depositary shares, and each may evidence any number of whole depositary shares.

Dividends and Other Distributions

The depositary will distribute all cash and non-cash distributions it receives, with respect to the underlying preferred stock, to the record holders of depositary shares in proportion to the number of depositary shares they hold. In the case of non-cash distributions, the depositary may determine that the distribution cannot be made proportionately or that it may not be feasible to make the distribution. If so, the depositary will, with our approval, adopt a method it deems equitable and practicable to effect the distribution, including the sale (public or private) of the securities or other non-cash property it receives in the distribution at a place and on terms it deems proper. Norfolk Southern or the depositary may reduce the amount it distributes in order to pay taxes or other governmental charges.

Redemption of Depositary Shares

If Norfolk Southern redeems the series of preferred stock that underlies the depositary shares, the depositary will redeem the depositary shares from the proceeds it receives from the redemption of the preferred stock it holds. The depositary will redeem the number of depositary shares that represent the amount of underlying preferred stock that Norfolk Southern redeemed. The redemption price per depositary share will be in proportion to the redemption price per share that Norfolk Southern paid for the underlying preferred stock. If Norfolk Southern redeems less than all the depositary shares, the depositary will select by lot, or by some substantially equivalent method, which depositary shares to redeem.

After a redemption date is fixed, the depositary shares to be redeemed no longer will be considered outstanding. The rights of the holders of the depositary shares will cease, except the right to receive money or other property they are entitled to receive upon the redemption. In order to redeem their depositary shares, holders will surrender their depositary receipts to the depositary. If Norfolk Southern deposits funds with the depositary to redeem depositary shares, and the holders fail to redeem their receipts, the money will be returned to Norfolk Southern within two years from the date the funds are deposited.

21

Voting the Preferred Stock

When Norfolk Southern notifies the depositary about any meeting at which the holders of preferred stock are entitled to vote, the depositary will mail the information to the record holders of depositary shares related to that preferred stock. Each record holder of such depositary shares on the record date (which will be the same date as the record date for the related preferred stock) will be entitled to instruct the depositary how to vote the shares of preferred stock represented by that holder’s depositary shares. The depositary will try to vote the preferred stock represented by the depositary shares in accordance with these instructions, provided the depositary receives these instructions sufficiently in advance of the meeting. Norfolk Southern will take all reasonable action necessary to provide the depositary with sufficient notice of any meeting. If the depositary does not receive instructions from the holders of the depositary shares, the depositary will abstain from voting the preferred stock that underlies those depositary shares.

Withdrawal of Preferred Stock

When a holder surrenders depositary receipts at the corporate trust office of the depositary, and pays any necessary taxes, charges or other fees, the holder will be entitled to receive the number of whole shares of the related series of preferred stock, and any money or other property, if any, represented by their depositary shares. Once a holder exchanges depositary shares for whole shares of preferred stock, that holder cannot “re-deposit” these shares of preferred stock with the depositary, or exchange them for depositary shares. If a holder delivers depositary receipts that represent a number of depositary shares that exceeds the number of whole shares of related preferred stock the holder seeks to withdraw, the depositary will issue a new depositary receipt to the holder that evidences the excess number of depositary shares.

Amendment and Termination of the Deposit Agreement

Norfolk Southern and the depositary can agree, at any time, to amend the form of depositary receipt and any provisions of the Deposit Agreement. However, if an amendment has a material adverse effect on the rights of the holders of related depositary shares, it must first be approved by the holders of at least a majority of these depositary shares then outstanding. Every holder of a depositary receipt at the time an amendment becomes effective will be bound by the amended Deposit Agreement. However, subject to any conditions in the Deposit Agreement or applicable law, no amendment can impair the right of any holder of a depositary share to receive shares of the related preferred stock, and any money or other property represented by the depositary shares, upon surrender the depositary receipts that represent their depositary shares.

Norfolk Southern can terminate the Deposit Agreement at any time, as long as it provides at least 60 days’ prior written notice to the depositary. If Norfolk Southern terminates the Deposit Agreement, then within 30 days from the date the depositary receives notice, the depositary will deliver whole or fractional shares of the related preferred stock to the holders of depositary shares, when they surrender their depositary receipts. The Deposit Agreement will terminate automatically after all outstanding depositary shares have been redeemed, or, in connection with any liquidation, dissolution or winding up of Norfolk Southern, after the final distribution of Norfolk Southern’s assets has been made to the holders of the related series of preferred stock and, in turn, to the holders of depositary shares.

Charges of Depositary

Norfolk Southern will pay the charges of the depositary, including charges in connection with the initial deposit of the related series of preferred stock, the initial issuance of the depositary shares, and all withdrawals of shares of the related series of preferred stock. Norfolk Southern also will pay all transfer and other taxes and the government charges that arise solely from the existence of the depositary arrangements. However, holders of depositary shares will have to pay all other transfer and other taxes and government charges, as provided in the Deposit Agreement.

22

Resignation and Removal of Depositary

The depositary may resign, at any time, by delivering written notice of its decision to Norfolk Southern. We may remove the depositary at any time. Any resignation or removal will take effect when we appoint a successor depositary. Norfolk Southern must appoint the successor depositary within 60 days after delivery of the notice of resignation or removal, and the successor depositary must be a bank or trust corporation that has its principal office in the United States, and has a combined capital and surplus of at least $50,000,000.

Miscellaneous

Norfolk Southern will be required to furnish certain information to the holders of the preferred stock. The depositary, as the holder of the underlying preferred stock, will forward any reports or information it receives from Norfolk Southern to the holders of depositary shares.

Neither the depositary nor Norfolk Southern will be liable if its ability to perform its obligations under the Deposit Agreement is prevented or delayed by law or any circumstance beyond its control. Both Norfolk Southern and the depositary will be obligated to use their best judgment and to act in good faith in performing their duties under the Deposit Agreement. Each of Norfolk Southern and the depositary will be liable for gross negligence and willful misconduct in the performance of its duties under the Deposit Agreement. They will not be obligated to appear in, prosecute or defend any legal proceeding with respect to any depositary receipts, depositary shares or preferred stock unless they receive what they, in their sole discretion, determine to be a satisfactory indemnity. Norfolk Southern and the depositary may rely on the advice of legal counsel (including in-house counsel) or accountants of their choice. They may also rely on information provided by persons they believe, in good faith, to be competent, and on documents they believe, in good faith, to be genuine.

The depositary’s corporate trust office will be identified in the related prospectus supplement. Unless the prospectus supplement indicates otherwise, the depositary will act as transfer agent and registrar for depositary receipts, and if Norfolk Southern redeems shares of preferred stock, the depositary will act as redemption agent for the corresponding depositary receipts.

DESCRIPTION OF STOCK PURCHASE CONTRACTS

AND STOCK PURCHASE UNITS

We may issue stock purchase contracts, including contracts obligating holders to purchase from or sell to us, and obligating us to sell to or purchase from the holders, a specified number of shares of common stock or other securities at a future date or dates, which we refer to in this prospectus as stock purchase contracts. The price per share of the securities and the number of shares of the securities may be fixed at the time the stock purchase contracts are issued or may be determined by reference to a specific formula set forth in the stock purchase contracts, and may be subject to adjustment under anti-dilution formulas. The stock purchase contracts may be issued separately or as part of units consisting of a stock purchase contract and debt securities, preferred securities or debt obligations of third parties, including U.S. treasury securities, any other securities described in the applicable prospectus supplement or any combination of the foregoing, securing the holders’ obligations to purchase the securities under the stock purchase contracts, which we refer to herein as stock purchase units. The stock purchase contracts may require holders to secure their obligations under the stock purchase contracts in a specified manner. The stock purchase contracts also may require us to make periodic payments to the holders of the stock purchase contracts or the stock purchase units, as the case may be, or vice versa, and those payments may be unsecured or pre-funded on some basis.

The applicable prospectus supplement will describe the terms of the stock purchase contracts or stock purchase units. This description is not complete and the description in the prospectus supplement will not necessarily be complete, and reference is made to the stock purchase contracts, and, if applicable, collateral or depositary arrangements relating to the stock purchase contracts or stock purchase units, which will be filed with the SEC each time we issue stock purchase contracts or stock purchase units. If any particular terms of the stock purchase contracts or stock purchase units described in the prospectus supplement differ from any of the terms described herein, then the terms described herein will be deemed superseded by that prospectus supplement. Material United States federal income tax considerations applicable to the stock purchase units and the stock purchase contracts will also be discussed in the applicable prospectus supplement.

PLAN OF DISTRIBUTION

We may sell the securities being offered hereby in one or more of the following ways from time to time:

In addition, we may enter into derivative or hedging transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. In connection with such a transaction, the third parties may sell securities covered by and pursuant to this prospectus and an applicable prospectus supplement. If so, the third party may use securities borrowed from us or others to settle such sales and may use securities received from us to close out any related short positions. We may also loan or pledge securities covered by this prospectus and an applicable prospectus supplement to third parties, who may sell the loaned securities or, in an event of default in the case of a pledge, sell the pledged securities pursuant to this prospectus and the applicable prospectus supplement.

We will identify the specific plan of distribution, including any underwriters, dealers, agents or direct purchasers and their compensation in a prospectus supplement.
