                        ABOUT THIS PROSPECTUS SUPPLEMENT

  This document is in two parts. The first part is the prospectus supplement,
which describes the specific terms of the Notes we are offering and certain
other matters relating to CSX. The second part, the base prospectus, gives more
general information about securities we may offer from time to time, some of
which does not apply to the Notes we are offering. Generally, when we refer to
the prospectus, we are referring to both parts of this document combined. If
the description of the Notes in the prospectus supplement differs from the
description in the base prospectus, the description in the prospectus
supplement supersedes the description in the base prospectus.

                                CSX CORPORATION

  CSX, headquartered in Richmond, Virginia, operates the largest rail network
in the eastern United States and also provides intermodal, container shipping
and international terminal services. CSX's goal, advanced at each of our
business units, is to provide efficient, competitive transportation and related
services for our customers and to deliver superior value to our shareholders.
Unless the context indicates otherwise, references in this prospectus to CSX
are to CSX Corporation and our consolidated subsidiaries. See "CSX Corporation"
in the accompanying base prospectus for additional information concerning CSX.

                                USE OF PROCEEDS

  It is expected that substantially all of the net proceeds from the sale of
the Notes will be used to refinance a portion of our outstanding commercial
paper. At February 28, 2001, CSX had approximately $676 million of commercial
paper outstanding. At February 28, 2001, the weighted average maturity of our
outstanding commercial paper was approximately 68.2 days and the weighted
average interest rate was approximately 6.7%. The balance, if any, of the net
proceeds will be used for general corporate purposes, which may include capital
expenditures, working capital requirements, implementation of work force
reductions, improvements in productivity and other cost reductions at our major
transportation units.

                              DESCRIPTION OF NOTES

  Set forth below is a description of the specific terms of the Notes. This
description supplements, and should be read together with, the description of
the general terms and provisions of the debt securities set forth in the
accompanying base prospectus under the caption "Description of Debt
Securities". The following description does not purport to be complete and is
subject to, and is qualified in its entirety by reference to, the description
in the base prospectus and the senior indenture. If the description of the
Notes in this prospectus supplement differs from the description of the debt
securities in the base prospectus, the description in this prospectus
supplement supersedes the description in the base prospectus. Capitalized terms
used in this Description of Notes that are not defined in this prospectus
supplement have the meanings given to them in the base prospectus or the senior
indenture.

General

  The Notes will initially be limited to $500,000,000 in aggregate principal
amount. The Notes will be issued in fully registered form only, in
denominations of $1,000 and integral multiples of $1,000, and will mature on
March 15, 2011. The Notes will be issued as a series of senior debt securities
under the senior indenture referred to in the accompanying base prospectus. The
senior indenture does not limit the amount of other debt that CSX may incur.
CSX may, from time to time, without the consent of the holders of Notes, issue
other debt securities under the senior indenture in addition to the
$500,000,000 aggregate principal amount of the Notes. CSX may also, from time
to time, without the consent of the holders, issue additional debt securities
having the same ranking and the same

                                      S-2


interest rate, maturity and other terms as the Notes. Any additional debt
securities having those similar terms, together with the Notes, will constitute
a single series of debt securities under the senior indenture.

  The Notes will bear interest from March 13, 2001, at the annual rate set
forth on the cover page of this prospectus supplement, payable semiannually on
March 15 and September 15 each year, commencing September 15, 2001, to the
persons in whose names the Notes are registered at the close of business on the
immediately preceding March 1 and September 1, respectively, whether or not
such day is a business day.

  The Notes will be unsecured obligations of CSX and will rank pari passu with
all other unsecured and unsubordinated indebtedness of CSX.

  The Notes do not provide for any sinking fund.

  For a description of the rights attaching to each series of debt securities
under the senior indenture, see "Description of Debt Securities" in the
accompanying prospectus.

  The provisions of the senior indenture described under "Description of Debt
Securities--Discharge, Defeasance and Covenant Defeasance" in the accompanying
base prospectus apply to the Notes.

Optional Redemption

  The Notes will be redeemable, in whole or in part, at our option at any time.
The redemption price for the Notes to be redeemed will equal the greater of the
following amounts, plus, in each case, accrued interest thereon to the
redemption date:

  .  100% of the principal amount of such Notes; or

  .  as determined by the Independent Investment Banker (as defined below),
     the sum of the present values of the remaining scheduled payments of
     principal and interest on the Notes (not including any portion of any
     payments of interest accrued as of the redemption date) discounted to
     the redemption date on a semiannual basis at the Adjusted Treasury Rate
     (as defined below) plus 20 basis points.

The redemption price will be calculated assuming a 360-day year consisting of
twelve 30-day months.

  "Adjusted Treasury Rate" means, with respect to any redemption date:

  .  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 remaining term of the Notes, yields for the two
     published maturities most closely corresponding to the Comparable
     Treasury Issue will be determined and the Adjusted Treasury Rate will be
     interpolated or extrapolated from such yields on a straight line basis,
     rounding to the nearest month); or

  .  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 semiannual equivalent yield to maturity of
     the Comparable Treasury Issue, assuming a price for the Comparable
     Treasury Issue (expressed as a percentage of its principal amount) equal
     to the Comparable Treasury Price for such redemption date.

                                      S-3


  The Adjusted Treasury Rate 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 comparable
to the remaining term of the Notes to be redeemed 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 comparable maturity to the
remaining term of such Notes.

  "Comparable Treasury Price" means, with respect to any redemption date, (A)
the average of five Reference Treasury Dealer Quotations for such redemption
date, after excluding the highest and lowest such Reference Treasury Dealer
Quotations, or (B) if the Independent Investment Banker obtains fewer than five
such Reference Treasury Dealer Quotations, the average of all such quotations.

  "Independent Investment Banker" means Goldman, Sachs & Co. and its
successors, or if that firm is unwilling or unable to serve as such, an
independent investment and banking institution of national standing appointed
by us.

  "Reference Treasury Dealer" means:

  .  Goldman, Sachs & Co. and its successors; provided that, if Goldman,
     Sachs & Co. ceases to be a primary U.S. Government securities dealer in
     New York City ("Primary Treasury Dealer"), we will substitute another
     Primary Treasury Dealer; and

  .  up to four other Primary Treasury Dealers selected by us.

  "Reference Treasury Dealer Quotation" means, with respect to each Reference
Treasury Dealer and any redemption date, the average, as determined by the
Independent Investment Banker, of the bid and asked prices for the Comparable
Treasury Issue (expressed in each case as a percentage of its principal amount)
quoted in writing to the Independent Investment Banker by such Reference
Treasury Dealer at 5:00 p.m. (New York City time) on the third business day
preceding such redemption date.

  We will mail notice of any redemption at least 30 days but not more than 60
days before the redemption date to each holder of the Notes to be redeemed. If
we elect to partially redeem the Notes, the trustee will select in a fair and
appropriate manner the Notes to be redeemed.

  Unless we default in payment of the redemption price, on and after the
redemption date interest will cease to accrue on the Notes or portions thereof
called for redemption.

Book-Entry Notes

  The Notes will be represented by one or more permanent global Notes in
definitive, fully registered form without interest coupons. Each beneficial
interest in a global Note is referred to as a book-entry Note. Each global Note
representing book-entry Notes will be deposited with the trustee, as custodian
for, and registered in the name of, a nominee of The Depository Trust Company,
as depositary, located in the Borough of Manhattan, The City of New York.

  Ownership of beneficial interests in book-entry Notes will be limited to
persons who have accounts with the depositary ("participants") or persons who
hold interests through participants. Ownership of beneficial interests in book-
entry Notes will be shown on, and the transfer of that ownership will be
effected only through, records maintained by the depositary or its nominee
(with respect to interests of participants) and the records of participants
(with respect to persons other than participants). The laws of some
jurisdictions require that certain purchasers of securities take physical
delivery of those securities in definitive form. Those laws may impair the
ability to transfer book-entry Notes.

                                      S-4


  So long as the depositary, or its nominee, is the registered owner or holder
of a global Note, the depositary or the nominee, as the case may be, will be
considered the sole owner or holder of the Notes represented by that global
Note for all purposes under the senior indenture and the Notes. No beneficial
owner of an interest in a global Note will be able to transfer that interest
except in accordance with the depositary's applicable procedures, in addition
to those provided for under the senior indenture.

  CSX has been advised by the depositary that upon the issuance of global Notes
representing book-entry Notes, and the deposit of those global Notes with the
depositary, the depositary will
immediately credit, on its book-entry registration and transfer system, the
respective principal amounts of the book-entry Notes represented by those
global Notes to the accounts of participants. The accounts to be credited shall
be designated by the underwriters.

  Payments of principal of and any premium and interest on book-entry Notes
will be made to the depositary or its nominee, as the case may be, as the
registered owner of those Notes. Those payments to the depositary or its
nominee, as the case may be, will be made in immediately available funds at the
offices of The Chase Manhattan Bank, as paying agent, in the Borough of
Manhattan, The City of New York, provided that, in the case of payments of
principal and any premium, the global Notes are presented to the paying agent
in time for the paying agent to make those payments in immediately available
funds in accordance with its normal procedures. None of CSX, the underwriters,
the trustee or any agent of CSX, the underwriters or the trustee will have any
responsibility or liability for any aspect of the depositary's records or any
participant's records relating to or payments made on account of book-entry
Notes or for maintaining, supervising or reviewing any of the depositary's
records or any participant's records relating to book-entry Notes.

  CSX expects that the depositary or its nominee upon receipt of any payment of
principal of or any premium or interest in respect of a global Note, will
immediately credit, on its book-entry registration and transfer system,
accounts of participants with payments in amounts proportionate to their
respective beneficial interests in the principal amount of the global Notes as
shown on the records of the depositary or its nominee. CSX also expects that
payments by participants to owners of beneficial interests in book-entry Notes
held through those participants will be governed by standing instructions and
customary practices, as is now the case with securities held for the accounts
of customers registered in "street name," and will be the responsibility of
those participants.

  Transfers between participants in the depositary will be effected in the
ordinary way in accordance with the depositary's rules and will be settled in
same-day funds.

  CSX expects that the depositary will take any action permitted to be taken by
a holder of Notes (including the presentation of Notes for exchange as
described below) only at the direction of one or more participants to whose
account or accounts the depositary interests in a global Note are credited and
only in respect of the portion of the aggregate principal amount of the Notes
as to which such participant or participants has or have given such direction.
However, if there is an event of default under the Notes, the depositary will
exchange the applicable global Note for definitive Notes in registered form,
which it will distribute to its participants.

  CSX understands that the depositary is a limited purpose trust company
organized under the laws of the State of New York, a "banking organization"
within the meaning of New York Banking Law, a member of the Federal Reserve
System, a "clearing corporation" within the meaning of the Uniform Commercial
Code, and a "Clearing Agency" registered pursuant to the provisions of Section
17A of the Exchange Act. The depositary was created to hold securities of its
participants and to facilitate the clearance and settlement of securities
transactions among participants through electronic book-entry changes in
accounts of its participants and certain other organizations, thereby
eliminating the need for physical movement of securities certificates. The
depositary's participants include securities brokers and dealers (including the
underwriters), banks, trust companies, clearing

                                      S-5


corporations, and certain other organizations, some of whom (or their
representatives) own interests in the depositary. Indirect access to the
depositary's book-entry system is also available to others, such as banks,
brokers, dealers and trust companies that clear through or maintain a custodial
relationship with a participant, either directly or indirectly ("indirect
participants").

  Although the depositary is expected to follow the foregoing procedures in
order to facilitate transfers of interests in a global Note among participants
of the depositary, it is under no obligation to perform or continue to perform
such procedures and such procedures may be discontinued at any time. Neither
CSX, the underwriters nor the trustee will have any responsibility for the
performance by the depositary or its respective participants or indirect
participants of its respective obligations under the rules and procedures
governing their operations.

  The global Notes representing book-entry Notes may not be transferred except
as a whole by a nominee of the depositary to the depositary or to another
nominee of the depository, or by the depository or the nominee to a successor
of the depositary or a nominee of the successor.

  The global Notes representing book-entry Notes are exchangeable for
definitive Notes in registered form, of like tenor and of an equal aggregate
principal amount, only if (x) the depositary notifies CSX that it is unwilling
or unable to continue as depositary for the global Note or if at any time the
depositary ceases to be a Clearing Agency registered under the Exchange Act and
a successor depositary is not appointed by CSX within 90 days, (y) CSX in its
sole discretion determines that the book-entry Notes will be exchangeable for
definitive Notes in registered form or (z) any event has happened and is
continuing which, after notice or lapse of time, or both, would become an event
of default with respect to the Notes. Any global Note representing book-entry
Notes that is exchangeable pursuant to the preceding sentence will be
exchangeable in whole for definitive Notes in registered form, of like tenor
and of an equal aggregate principal amount, in denominations of U.S. $1,000 and
integral multiples of U.S. $1,000. Upon the exchange of a global Note for
definitive Notes, that global Note will be canceled by the trustee and the
definitive Notes will be registered in the names and in the authorized
denominations as the depositary, pursuant to instructions from its
participants, any indirect participants or otherwise, instruct the trustee. The
trustee will deliver such Notes to the persons in whose names those Notes are
registered and will recognize those persons as the holders of those Notes.

  Except as provided above, owners of book-entry Notes will not be entitled to
receive physical delivery of Notes in definitive form and will not be
considered the holders of those Notes for any purpose under the senior
indenture, and no global Note representing book-entry Notes will be
exchangeable, except for another global Note of like denomination and tenor to
be registered in the name of the depositary or its nominee. Accordingly, each
person owning a book-entry Note must rely on the procedures of the depositary
and, if that person is not a participant, on the procedures of the participant
through which that person owns its interest, to exercise any rights of a holder
under that global Note or the senior indenture. The senior indenture provides
that the depositary, as a holder, may appoint agents and otherwise authorize
participants to give or take any request, demand, authorization, direction,
notice, consent, waiver or other action which a holder is entitled to give or
take under the senior indenture. CSX understands that under existing industry
practices, if CSX requests any action of holders or an owner of a book-entry
Note desires to give or take any action a holder is entitled to give or take
under the senior indenture, the depositary would authorize the participants
owning the relevant book-entry Notes to give or take that action, and those
participants would authorize beneficial owners owning through those
participants to give or take that action or would otherwise act upon the
instructions of beneficial owners owning through them.

                                  UNDERWRITING

  CSX and the underwriters for the offering named below have entered into an
underwriting agreement with respect to the Notes. Subject to certain
conditions, each underwriter has severally agreed to purchase the principal
amount of Notes indicated in the following table.



                                                                Principal Amount

  Total........................................................   $500,000,000
                                                                  ============


  Notes sold by the underwriters to the public will initially be offered at the
initial public offering price set forth on the cover of this prospectus
supplement. Any Notes sold by the underwriters to securities dealers may be
sold at a discount from the initial public offering price of up to 0.40% of the
principal amount of the Notes. Those securities dealers may resell any Notes
purchased from the underwriters to certain other brokers or dealers at a
discount from the initial public offering price of up to 0.25% of the principal
amount of the Notes. If all the Notes are not sold at the initial offering
price, the underwriters may change the offering price and the other selling
terms.

  The Notes are a new issue of securities with no established trading market.
CSX has been advised by the underwriters that the underwriters intend to make a
market in the Notes, but they are not obligated to do so and may discontinue
market making at any time without notice. No assurance can be given as to the
liquidity of the trading market for the Notes.

  In connection with the offering, the underwriters may purchase and sell Notes
in the open market. These transactions may include short sales, stabilizing
transactions and purchases to cover positions created by short sales. Short
sales involve the sale by the underwriters of a greater number of Notes than
they are required to purchase in the offering. Stabilizing transactions consist
of certain bids or purchases made for the purpose of preventing or retarding a
decline in the market price of the Notes while the offering is in progress.

  The underwriters also may impose a penalty bid. This occurs when a particular
underwriter repays to the underwriters a portion of the underwriting discount
received by it because the underwriters have repurchased Notes sold by or for
the account of such underwriter in stabilizing or short covering transactions.

  These activities by the underwriters may stabilize, maintain or otherwise
affect the market price of the Notes. As a result, the price of the Notes may
be higher than the price that otherwise might exist in the open market. If
these activities are commenced, they may be discontinued by the underwriters at
any time. These transactions may be effected in the over-the-counter market or
otherwise.

  CSX estimates that its share of the total expenses of the offering, excluding
underwriting discounts and commissions, will be approximately $250,000.

  The underwriters or their respective affiliates have performed and may in the
future perform various financial advisory, commercial banking and investment
banking services for CSX from time to time, for which they received or will
receive customary fees.

                                      S-7


  CSX has agreed to indemnify the several underwriters against certain
liabilities, including liabilities under the Securities Act of 1933.

                                 LEGAL MATTERS

  Certain legal matters in connection with the offering of the Notes will be
passed upon for CSX by McGuireWoods LLP, Richmond, Virginia, and for the
underwriters by Shearman & Sterling, New York, New York. Robert L. Burrus, Jr.,
a partner of McGuireWoods LLP, is a director of CSX and owns 15,729 shares of
CSX common stock.

  This prospectus is part of a shelf registration statement that CSX
Corporation filed with the Securities and Exchange Commission. Under the shelf
registration statement, CSX may sell any combination of the securities
described in this prospectus in one or more offerings up to a total dollar
amount of $800,000,000. For further information about our business and the
securities, you should refer to the registration statement and its exhibits.
The exhibits to the registration statement and the documents we incorporate by

documents. The registration statement can be obtained from the SEC as indicated
under the heading "Where You Can Find More Information."

  This prospectus provides you with a general description of the securities CSX
may offer. Each time CSX sells securities, we will provide a prospectus
supplement that will contain specific information about the terms of that
offering. Material United States federal income tax considerations will also be
discussed in the applicable prospectus supplement. The prospectus supplement
may also add, update or change information contained in this prospectus. You

                           FORWARD-LOOKING STATEMENTS

  This prospectus, including documents incorporated by reference, contains
forward-looking statements within the meaning of Section 27A of the Securities
Act of 1933, as amended (the "Securities Act"), and Section 21E of the Exchange
Act. Estimates, forecasts and other forward-looking statements included, or
incorporated by reference, in this prospectus are based on many assumptions
about complex economic and operating factors with respect to industry
performance, general business and economic conditions and other matters that
cannot be predicted accurately and that are subject to contingencies over which
CSX has no control. Forward-looking statements are subject to uncertainties and
other factors that may cause actual results to differ materially from the
views, beliefs, and projections expressed in those statements. The words
"believe," "expect," "anticipate," "project," and similar expressions signify
forward-looking statements.

  Factors that may cause actual results to differ materially from those
contemplated by these forward-looking statements include, among others, the
following possibilities:

  .  costs and operating difficulties related to the integration of the
     Conrail rail system may not be eliminated or resolved within the time
     frame currently anticipated and revenue and cost synergies expected from
     the integration of Conrail may not be fully realized or realized within
     the time frame anticipated;

  .  general economic or business conditions, either nationally or
     internationally, an increase in fuel prices, a tightening of the labor
     market or changes in demands of organized labor resulting in higher
     wages, or increased benefits or other costs or disruption of operations
     may adversely affect our businesses;

  .  legislative or regulatory changes, including possible enactment of new
     initiatives with respect to the environment or initiatives to re-
     regulate the rail industry, may adversely affect our businesses;

  .  possible additional consolidation of the rail industry in the near
     future may adversely affect our operations and business; and

  .  changes may occur in the securities and capital markets.

  You are cautioned not to place undue reliance on any forward-looking
statements made by or on behalf of CSX. These forward-looking statements speak
only as of the date the statement was made. We undertake no obligation to
update or revise any forward-looking statement.

                       RATIO OF EARNINGS TO FIXED CHARGES

  CSX's consolidated ratio of earnings to fixed charges for each of the fiscal
periods indicated is as follows:



                                           For the Fiscal Years Ended
                                  --------------------------------------------
                                  Dec. 29, Dec. 31, Dec. 25, Dec. 26, Dec. 27,
                                    2000     1999     1998     1997     1996
                                  -------- -------- -------- -------- --------
                                                       
Ratio of earnings to fixed
 charges(a)(b)(c)(d).............   1.4x     1.1x     1.7x     2.5x     3.9x

- --------
(a) For purposes of computing the ratio of earnings to fixed charges, earnings
    represent earnings from operations before income taxes plus interest
    expense related to indebtedness, amortization of debt discount, the
    interest portion of fixed rent expense, and undistributed earnings of
    affiliates accounted for using the equity method. Fixed charges include
    interest on indebtedness (whether expensed or capitalized), amortization of
    debt discount and the interest portion of fixed rent expense.

                                       5


(b) The year ended December 27, 1996 was prior to the acquisition of CSX's
    interests in Conrail Inc. and therefore do not include the increased
    interest expense incurred by CSX subsequent to that transaction.
(c) All periods' calculations have been restated to exclude from earnings, the
    activities of CSX's contract logistics segment which was sold in September
    2000.
(d) Pretax earnings for certain periods include the effects of various non-
    recurring gains and charges. These items are summarized as follows:
  (1) A pretax loss of $360 million related to an impairment charge related
      to the sale of assets comprised of the international liner business of
      Sea-Land and certain container terminal facilities is included in the
      year ended December 31, 1999.
  (2) A pretax gain of $27 million from the sale of CSX's investment in Grand
      Teton Lodge Company, a wholly-owned subsidiary located in Jackson Hole,
      Wyoming is included in the year ended December 31, 1999.
  (3) A pretax gain of $154 million primarily from the conveyance of CSX's
      barge subsidiary to a joint venture is included for the year ended
      December 25, 1998.
  (4) A restructuring credit of $30 million to reverse a charge taken in 1995
      related to a restructuring plan is included for the year ended December
      25, 1998.

  Excluding these items, the ratio of earnings to fixed charges for each of the
   periods indicated below would have been:

    Fiscal year ended December 31, 19991.5x
    Fiscal year ended December 25, 19981.4x

                                USE OF PROCEEDS

  CSX will use the net proceeds from the sale of the securities for general
corporate purposes, which may include reduction or refinancing of outstanding
indebtedness, capital expenditures, working capital requirements,
implementation of work force reductions, improvements in productivity and other
cost reductions at our major transportation units, and redemptions and
repurchases of certain outstanding securities. CSX has not specifically
allocated the proceeds to those purposes as of the date of this prospectus. The
precise amount and timing of the application of proceeds from the sale of
securities will depend upon the funding requirements of CSX and the
availability and cost of other funds at the time of the sale. Allocation of the
proceeds of a particular series of securities, or the principal reasons for the
offering if no allocation has been made, will be described in the applicable
prospectus supplement.

                         DESCRIPTION OF DEBT SECURITIES

  CSX may issue debt securities either separately, or together with, or upon
the conversion of or in exchange for, other securities. The debt securities
will be either senior unsecured obligations or subordinated unsecured
obligations of CSX. Senior debt securities will be issued under a senior
indenture dated as of August 1, 1990 between CSX and The Chase Manhattan Bank,
as trustee, as supplemented by a First Supplemental Indenture dated as of June
15, 1991, a Second Supplemental Indenture dated as of May 6, 1997 and a Third
Supplemental Indenture dated as of April 22, 1998. Subordinated debt securities
will be issued under a subordinated indenture to be entered into between CSX
and The Chase Manhattan Bank, as trustee. A copy of the senior indenture and
the subordinated indenture have been incorporated by reference in, or filed as
an exhibit to, the registration statement of which this prospectus is a part.
The senior indenture and the subordinated indenture are sometimes referred to
collectively as the "indentures". The trustee under the senior indenture and
the trustee under the subordinated indenture are sometimes referred to
collectively as the "trustees".

  The summary of certain provisions of the indentures and the debt securities
set forth below and the summary of certain terms of a particular series of debt
securities set forth in the applicable prospectus supplement do not purport to
be complete and are subject to and are qualified in their entirety by reference
to all of the provisions of the indentures, which provisions of the indentures
(including defined terms) are incorporated in this description of debt
securities by reference.

  The debt securities may be issued from time to time in one or more series of
senior debt securities and one or more series of subordinated debt securities.
Neither indenture limits the aggregate principal amount of debt securities that
may be issued under it and provides that debt securities of any series may be
issued under that indenture up to an aggregate principal amount that may be
authorized from time to time by CSX. The terms of each series of debt
securities will be established by or pursuant to a resolution of our Board of
Directors and set forth or determined in the manner provided in an officer's
certificate or by a supplemental indenture. The following description of debt
securities summarizes certain general terms and provisions of the series of
debt securities to which any prospectus supplement may relate. The particular
terms of each series of debt securities offered by a prospectus supplement or
prospectus supplements will be described in the prospectus supplement or
prospectus supplements relating to that series.

  Unless otherwise indicated, currency amounts in this prospectus and any
prospectus supplement are stated in United States dollars.

     manner in which, or the person to whom, any interest on any bearer debt
     security of the series will be payable, if otherwise than upon
     presentation and surrender of the applicable coupons, and the extent to
     which, or the manner in which, any interest payable on a temporary
     global debt security on an interest payment date will be paid if other

     described below under "Form, Exchange, Registration and Transfer," the
     debt securities may be presented for registration of transfer or
     exchange;

  .  the period or periods within which and the price or prices at which the
     debt securities may, pursuant to any optional redemption provisions, be
     redeemed, in whole or in part, at our option and the other detailed
     terms and conditions of any optional redemption provisions;

  .  the obligation, if any, of CSX to redeem or purchase the debt securities
     pursuant to any sinking fund or analogous provisions or at the option of
     the holder of the debt securities and the period or periods within which

  .  the terms, if any, upon which the debt securities may be convertible
     into or exchangeable for other securities;

  .  whether the debt securities will be senior debt securities or
     subordinated debt securities; and

     provisions of the relevant indenture.

                                       8


  The prospectus supplement will also describe any special provisions for the
payment of additional amounts relating to specified taxes, assessments or other
governmental charges in respect of the debt securities of that series and
whether CSX has the option to redeem the affected debt securities rather than
pay those additional amounts.

  As used in this prospectus and any prospectus supplement relating to the
offering of any debt securities, references to the principal of and premium, if
any, and interest, if any, on the debt securities will be deemed to include
mention of the payment of additional amounts, if any, required by the terms of
the debt securities.

  If the purchase price of any debt securities is payable in a currency other
than U.S. dollars or if principal of, or premium, if any, or interest, if any,
on any of the debt securities is payable in any currency other than U.S.
dollars, the specific terms and other information with respect to those debt
securities and that currency will be specified in the related prospectus
supplement.

  Debt securities of a series may also be issued under the indenture upon the
exercise of debt warrants issued by CSX. See "Description of Debt Warrants."

  The indentures do not contain any provisions that may afford the holders of
debt securities of any series protection in the event of a highly leveraged
transaction or other transaction that may occur in connection with a takeover
attempt resulting in a decline in the credit rating of the debt securities.
Those provisions, if applicable to the debt securities of any series, will be
described in the related prospectus supplement.

Form, Exchange, Registration and Transfer

  Unless otherwise indicated in the applicable prospectus supplement, each
series of debt securities will be issued in registered form only, without
coupons. The indentures, however, provide that CSX may also issue debt
securities in bearer form only, or in both registered and bearer form. Bearer
debt securities shall not be offered, sold, resold or delivered in connection
with their original issuance in the United States or to any United States
person other than offices located outside the United States of certain United
States financial institutions. Purchasers of bearer debt securities will be
subject to certification procedures and may be affected by certain limitations
under United States tax laws. Those procedures and limitations will be
described in the prospectus supplement relating to the offering of the bearer
debt securities. Unless otherwise indicated in an applicable prospectus
supplement or prospectus supplements, bearer debt securities will have interest
coupons attached. The indentures also will provide that debt securities of a
series may be issuable in temporary or permanent global form. See "Global Debt
Securities."

  At the option of the holder, subject to the terms of the relevant indenture,
registered debt securities of any series will be exchangeable for other
registered debt securities of the same series of any authorized denominations
and of a like aggregate principal amount and tenor. In addition, if debt
securities of any series are issuable as both registered debt securities and
bearer debt securities, at the option of the holder, subject to the terms of
the relevant indenture, bearer debt securities (with all unmatured coupons,
except as provided below, and with all matured coupons in default) of that
series will be exchangeable for registered debt securities of the same series
of any authorized denominations and of a like aggregate principal amount and
tenor. Bearer debt securities surrendered in exchange for registered debt
securities between a regular record date or a special record date and the
relevant date for payment of interest shall be surrendered without the coupon
relating to that date for payment of interest and interest will not be payable
in respect of the registered debt security issued in exchange for that bearer
debt security, but will be payable only to the holder of the coupon when due in
accordance with the terms of the indenture. Registered debt securities,
including registered debt securities received in exchange for bearer debt
securities, may

                                       9


not be exchanged for bearer debt securities. Each bearer debt security and
coupon will bear a legend to the following effect:

  "Any United States person who holds this obligation will be subject to
  limitations under the United States income tax laws, including the
  limitations provided in Sections 165(j) and 1287(a) of the Internal Revenue
  Code."

  Debt securities may be presented for exchange as provided above, and
registered debt securities may be presented for registration of transfer (with
the form of transfer duly executed), at the office of the security registrar or
at the office of any transfer agent designated by CSX for that purpose with
respect to any series of debt securities and referred to in an applicable
prospectus supplement, without a service charge and upon payment of any taxes
and other governmental charges as described in the relevant indenture. The
transfer or exchange will be effected upon the records of the security
registrar or the transfer agent, as the case may be, being satisfied with the
documents of title and identity of the person making the request. CSX has
appointed the trustee as security registrar. If a prospectus supplement refers
to any transfer agent (in addition to the security registrar) initially
designated by CSX with respect to any series of debt securities, CSX may at any
time rescind the designation of that transfer agent or approve a change in the
location through which that transfer agent acts, except that, if debt
securities of a series are issuable solely as registered debt securities, CSX
will be required to maintain a transfer agent in each place of payment for that
series and, if debt securities of a series are issuable as bearer debt
securities, CSX will be required to maintain (in addition to the security
registrar) a transfer agent in a place of payment for that series located
outside the United States and its possessions. CSX may at any time designate
additional transfer agents with respect to any series of debt securities.

  In the event of any partial redemption, CSX will not be required to

  .  issue, register the transfer of or exchange any debt security during a
     period beginning at the opening of business 15 days before any selection
     for redemption of debt securities of like tenor and of the series of
     which that debt security is a part, and ending at the close of business
     on the earliest date on which the relevant notice of redemption is
     deemed to have been given to all holders of debt securities of like
     tenor and of the series to be redeemed;

  .  register the transfer of or exchange any registered debt security so
     selected for redemption, in whole or in part, except the unredeemed
     portion of any debt security being redeemed in part; or

  .  exchange any bearer debt security so selected for redemption, except to
     exchange that bearer debt security for a registered debt security of
     that series and like tenor which is immediately surrendered for
     redemption.

Payment and Paying Agents

  Unless otherwise indicated in an applicable prospectus supplement, principal
of and any premium and interest on bearer debt securities will be payable,
subject to any applicable laws and regulations, at the offices of paying agents
outside the United States and its possessions that CSX may designate from time
to time or, at the option of the holder, by check or by transfer to an account
maintained by the payee with a financial institution located outside the United
States and its possessions. Unless otherwise indicated in an applicable
prospectus supplement, payment of interest on a bearer debt security on any
interest payment date will be made only against surrender to the paying agent
of the coupon relating to that interest payment date. No payment with respect
to any bearer debt security will be made at any office or agency of CSX in the
United States or its possessions or by check mailed to any address in the
United States or its possessions or by transfer to any account maintained with
a financial institution located in the United States or its possessions.

                                       10


However, payments of principal of and any premium and interest on bearer debt
securities denominated and payable in U.S. dollars will be made at the office
of the paying agent in the Borough of Manhattan, The City of New York, if (but
only if) payment of the full amount in U.S. dollars at all offices or agencies
outside the United States and its possessions is illegal or effectively
precluded by exchange controls or other similar restrictions.

  Unless otherwise indicated in an applicable prospectus supplement, principal
of and any premium and interest on registered debt securities will be payable,
subject to any applicable laws and regulations, at the office of the paying
agent or paying agents that CSX may designate from time to time, except that at
our option payment of any interest may be made by check mailed to the address
of the person entitled to that payment as that address appears in the security
register. Unless otherwise indicated in an applicable prospectus supplement,
payment of interest on a registered debt security on any interest payment date
will be made to the person in whose name that registered debt security (or
predecessor debt security) is registered at the close of business on the
regular record date for that interest.

  Unless otherwise indicated in an applicable prospectus supplement, the
corporate trust office of the trustee in The City of New York will be
designated as a paying agent for CSX for payments with respect to debt
securities of each series which are issuable solely as registered debt
securities and as a paying agent for payments with respect to debt securities
of each series (subject to the limitations described above in the case of
bearer debt securities) which are issuable solely as bearer debt securities or
as both registered debt securities and bearer debt securities. Any paying
agents outside the United States and its possessions and any other paying
agents in the United States or its possessions initially designated by CSX for
the debt securities of each series will be named in the applicable prospectus
supplement. CSX may at any time designate additional paying agents or rescind
the designation of any paying agent or approve a change in the office through
which any paying agent acts, except that if debt securities of a series are
issuable solely as registered debt securities, CSX will be required to maintain
a paying agent in each place of payment for that series and, if debt securities
of a series are issuable as bearer debt securities, CSX will be required to
maintain

  .  a paying agent in the Borough of Manhattan, The City of New York for
     payments with respect to any registered debt securities of the series
     (and for payments with respect to bearer debt securities of the series
     in the circumstances described above, but not otherwise), and

  .  a paying agent in a place of payment located outside the United States
     and its possessions where debt securities of that series and any related
     coupons may be presented and surrendered for payment;

provided, however, that if the debt securities of that series are listed on The
International Stock Exchange of the United Kingdom and the Republic of Ireland
Limited, the Luxembourg Stock Exchange or any other stock exchange located
outside the United States and its possessions and that stock exchange requires
CSX to do so, CSX will maintain a paying agent in London, Luxembourg or any
other required city located outside the United States and its possessions, as
the case may be, for the debt securities of that series.

  All moneys paid by CSX to a paying agent for the payment of the principal of
and any premium or interest on any debt security of any series which remain
unclaimed at the end of two years after that principal, premium or interest has
become due and payable will be repaid to CSX and the holder of that debt
security or any related coupon will after that time look only to CSX for
payment of that principal, premium or interest.

                                       11


Ranking of Debt Securities; Holding Company Structure

  The senior debt securities will be unsecured unsubordinated obligations of
CSX and will rank on a parity in right of payment with all other unsecured and
unsubordinated indebtedness of CSX. The subordinated debt securities will be
unsecured obligations of CSX and will be subordinated in right of payment to
all existing and future senior indebtedness (as defined below) of CSX. See "--
Subordination of Subordinated Debt Securities."

  The debt securities are obligations exclusively of CSX. CSX is a holding
company, substantially all of whose consolidated assets are held by our
subsidiaries. Accordingly, the cash flow of CSX and the consequent ability to
service our debt, including the debt securities, are largely dependent upon the
earnings of those subsidiaries.

  Because CSX is a holding company, the debt securities will be effectively
subordinated to all existing and future indebtedness, trade payables,
guarantees, lease obligations and letter of credit obligations of CSX's
subsidiaries. Therefore, CSX's rights and the rights of our creditors,
including the holders of the debt securities, to participate in the assets of
any subsidiary upon the latter's liquidation or reorganization will be subject
to the prior claims of that subsidiary's creditors, except to the extent that
CSX may itself be a creditor with recognized claims against the subsidiary, in
which case the claims of CSX would still be effectively subordinate to any
security interest in, or mortgages or other liens on, the assets of that
subsidiary and would be subordinate to any indebtedness of that subsidiary
senior to that held by CSX. Although certain debt instruments to which CSX and
our subsidiaries are parties impose limitations on the incurrence of additional
indebtedness, both CSX and our subsidiaries retain the ability to incur
substantial additional indebtedness and lease and letter of credit obligations.

Global Debt Securities

  The debt securities of a series may be issued in whole or in part in the form
of one or more global securities that will be deposited with, or on behalf of,
a depositary identified in the prospectus supplement relating to that series.
Global debt securities may be issued in either registered or bearer form and in
either temporary or permanent form. Unless and until it is exchanged in whole
or in part for individual certificates evidencing debt securities in definitive
form, a global debt security may not be transferred except as a whole by the
depositary for that global debt security to a nominee of the depositary or by a
nominee of the depositary to the depositary or another nominee of the
depositary or by the depositary or any nominee to a successor of the depositary
or a nominee of the successor.

  The specific terms of the depositary arrangement with respect to a series of
global debt securities and certain limitations and restrictions relating to a
series of global bearer debt securities will be described in the prospectus
supplement relating to that series.

Redemption and Repurchase

  The debt securities of any series may be redeemable at our option, may be
subject to mandatory redemption pursuant to a sinking fund or otherwise, or may
be subject to repurchase by us at the option of the holders, in each case upon
the terms, at the times and at the prices set forth in the applicable
prospectus supplement.

Conversion and Exchange

  The terms, if any, on which debt securities of any series are convertible
into or exchangeable for our common stock, preferred stock, depositary shares
or other debt securities will be set forth in the applicable prospectus
supplement. Those terms may include provisions for conversion or exchange,
either mandatory, at the option of the holders or at our option.

                                       12


Certain Covenants and Agreements of CSX

  The indentures do not limit the amount of indebtedness or lease obligations
that may be incurred by CSX and our subsidiaries. The indentures do not contain
provisions that would give holders of the debt securities the right to require
CSX to repurchase their debt securities in the event of a decline in the credit
rating of our debt securities resulting from a takeover, recapitalization or
similar restructuring.

 Covenant in the Senior Indenture--Limitation on Liens on Stock of Our
Principal Subsidiaries.

  The following covenant will be applicable to senior debt securities but not
to subordinated debt securities. The senior indenture provides that CSX may
not, nor may it permit any subsidiary to, create, assume, incur or suffer to
exist any mortgage, pledge, lien, encumbrance, charge or security interest of
any kind upon any stock or indebtedness, whether owned on the date of the
senior indenture or acquired later, of any principal subsidiary, to secure any
obligation (other than the senior debt securities) of CSX, any subsidiary or
any other person, unless all of the outstanding senior debt securities (and
other outstanding debt securities issued from time to time pursuant to the
senior indenture) will be directly secured equally and ratably with that
obligation. This provision does not restrict any other property of CSX or our
subsidiaries. The senior indenture defines "obligation" as indebtedness for
money borrowed or indebtedness evidenced by a bond, note, debenture or other
evidence of indebtedness; "principal subsidiary" as CSXT and SL Service, Inc.;
and "subsidiary" as a corporation a majority of the outstanding voting stock of
which is owned, directly or indirectly, by CSX or one or more subsidiaries, or
by CSX and one or more subsidiaries. The indentures do not prohibit the sale by
CSX or any subsidiary of any stock or indebtedness of any subsidiary, including
any principal subsidiary.

 Provision in Both Indentures--Consolidation, Merger and Sale of Assets.

  The following provision will be applicable to both senior debt securities and
subordinated debt securities. Each indenture provides that CSX may, without the
consent of the holders of any of the outstanding debt securities of a series,
consolidate with, merge into or transfer our assets substantially as an
entirety to any corporation organized under the laws of any domestic or foreign
jurisdiction, provided that

  .  the successor corporation assumes, by a supplemental indenture, CSX's
     obligations on the debt securities of each series and under the
     indenture,

  .  after giving effect to the transaction, no event of default, and no
     event which, after notice or lapse of time, or both, would become an
     event of default will have occurred and be continuing, and

  .  CSX delivers to the relevant trustee an officer's certificate and an
     opinion of counsel each stating that the transaction and supplemental
     indenture, if any, comply with the applicable article of the indenture
     and that all conditions precedent in the indenture relating to the
     transaction have been complied with.

Events of Default

  An "event of default" with respect to the debt securities of any series is
defined in the relevant indenture as being a:

  .  failure to pay principal of or any premium on any of the debt securities
     of that series when due;

                                       13


  .  failure to pay any interest on any debt security of that series when
     due, continued for 30 days;

  .  failure to deposit any sinking fund payment, when due, in respect of any
     debt security of that series;

  .  failure to perform any other covenant of CSX in the relevant indenture
     (other than a covenant included in that indenture solely for the benefit
     of series of debt securities other than that series) continued for 90
     days after written notice as provided in the indenture;

  .  certain events of bankruptcy, insolvency or reorganization of CSX; or

  .  any other event of default provided with respect to debt securities of
     that series.

  No event of default with respect to any particular series of debt securities
necessarily constitutes an event of default with respect to any other series of
debt securities. Each indenture provides that the trustee may withhold notice
to the holders of the debt securities of any series of the occurrence of a
default with respect to the debt securities of that series (except a default in
payment of principal, premium, if any, interest, if any, or sinking fund
payments, if any) if the trustee considers it in the interest of the holders to
do so.

  Subject to the provisions of the Trust Indenture Act of 1939 requiring each
trustee, during an event of default under the relevant indenture, to act with
the requisite standard of care, and to the provisions of the relevant indenture
relating to the duties of the trustee in case an event of default occurs and is
continuing, a trustee will be under no obligation to exercise any of its rights
or powers under the indenture at the request or direction of any of the holders
of debt securities of any series or any related coupons unless those holders
offer to the trustee reasonable indemnity. Subject to the provisions for the
indemnification of the relevant trustee, the holders of a majority in aggregate
principal amount of the outstanding debt securities of any series will have the
right to direct the time, method and place of conducting any proceeding for any
remedy available to the relevant trustee, or exercising any trust or power
conferred on the trustee, with respect to debt securities of that series.

  If an event of default with respect to debt securities of any series at the
time outstanding occurs and is continuing, either the relevant trustee or the
holders of at least 25% in aggregate principal amount of the outstanding debt
securities of that series may declare the principal of all those outstanding
debt securities to be due and payable immediately. At any time after a
declaration of acceleration with respect to debt securities of any series has
been made but before a judgment or decree for payment of money due has been
obtained by the relevant trustee, the holders of a majority in aggregate
principal amount of outstanding debt securities of that series may rescind any
declaration of acceleration and its consequences, if all payments due (other
than those due as a result of acceleration) have been made and all events of
default have been cured or waived.

  No holder of any debt securities of any series or any related coupons will
have any right to institute any proceeding with respect to the relevant
indenture or for any remedy under the indenture, unless that holder has
previously given to the relevant trustee written notice of a continuing event
of default with respect to debt securities of that series, the holders of at
least 25% in aggregate principal amount of the outstanding debt securities of
that series have made written request, and offered reasonable indemnity, to the
relevant trustee to institute the proceeding as trustee, and the trustee has
not received from the holders of a majority in aggregate principal amount of
the outstanding debt securities of that series a direction inconsistent with
that request and has failed to institute the proceeding within 60 days.
However, these limitations do not apply to a suit instituted by a holder of an
outstanding debt security of that series for enforcement of payment of the
principal of, or any premium or interest on, that debt security on or after the
respective due dates expressed in that debt security.

                                       14


  CSX is required to furnish to the relevant trustee annually a statement as to
performance or fulfillment of covenants, agreements or conditions in the
relevant indenture and as to the absence of default.

Meetings, Modification and Waiver

  Each indenture contains provisions permitting CSX and the relevant 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 issued under
that indenture and affected by a modification or amendment (voting as one
class), to modify or amend any of the provisions of that indenture or of those
debt securities or the rights of the holders of those debt securities under
that indenture, provided that no modification or amendment will, without the
consent of each holder of each outstanding debt security affected by that
modification or amendment:

  .  change the stated maturity of the principal of, or any installment of
     principal of or interest on, any debt security, or reduce the principal
     amount of or the rate of interest on or any premium payable upon the
     redemption of any debt security, or change any obligation of CSX to pay
     additional amounts (except as contemplated and permitted by the
     indenture), or reduce the amount of the principal of an original issue
     discount security that would be due and payable upon a declaration of
     acceleration of the maturity of that security or change the coin or
     currency in which any debt security or any premium or interest on any
     debt security is payable, or impair the right to institute suit for the
     enforcement of any payment on or after the stated maturity of any debt
     security (or, in the case of redemption, on or after the redemption
     date),

  .  reduce the percentage in principal amount of the debt securities, the
     consent of the holders of which is required for any modification or
     amendment or the consent of whose holders is required for any waiver (of
     compliance with certain provisions of the indenture or certain defaults
     under the indenture and their consequences) or reduce the requirements
     for a quorum or voting at a meeting of holders of the debt securities,

  .  change any obligation of CSX to maintain an office or agency in the
     places and for the purposes required by the indenture,

  .  solely in the case of the subordinated indenture, modify any of the
     provisions of the subordinated indenture relating to subordination of
     the subordinated debt securities or the definition of senior
     indebtedness in a manner adverse to the holders of the subordinated debt
     securities, or

  .  modify any of the above provisions (except as permitted by the
     indenture).

  Each indenture also contains provisions permitting CSX and the relevant
trustee, without the consent of the holders of the debt securities issued under
the indenture, to modify or amend the indenture in order, among other things:

  .  to add any additional events of default or add to the covenants of CSX
     for the benefit of the holders of all or any series of debt securities
     issued under the indenture;

  .  to establish the form or terms of debt securities of any series;

  .  to cure any ambiguity, to correct or supplement any provision in the
     indenture which may be inconsistent with any other provision in the
     indenture, or to make any other provisions with respect to matters or
     questions arising under the indenture which shall not adversely affect
     the interests of the holders of any debt securities issued under the
     indenture in any material respect; or

                                       15


  .  to change or eliminate any of the provisions of the indenture, provided
     that the change or elimination will become effective only when there is
     no debt security outstanding of any series issued under the indenture
     created prior to the execution of the supplemental indenture which is
     entitled to the benefit of that provision.

  The holders of at least a majority in aggregate principal amount of the
outstanding debt securities of a series may, on behalf of the holders of all
the debt securities of that series, waive, insofar as that series is concerned,
compliance by CSX with certain restrictive provisions of the indenture,
including the covenant described above under "--Certain Covenants and
Agreements of CSX--Covenant in the Senior Indenture--Limitation on Liens on
Stock of Our Principal Subsidiaries." The holders of not less than a majority
in aggregate principal amount of the outstanding debt securities of a series
may, on behalf of all holders of debt securities of that series and any related
coupons, waive any past default under the indenture with respect to debt
securities of that series, except a default (a) in the payment of principal of
or any premium or interest on any debt security of that series or (b) in
respect of a covenant or provision of the indenture which cannot be modified or
amended without the consent of the holder of each outstanding debt security of
the series affected.

  Each indenture provides that in determining whether the holders of the
requisite principal amount of the outstanding debt securities have given any
request, demand, authorization, direction, notice, consent or waiver under that
indenture or are present at a meeting of holders of debt securities for quorum
purposes,

  (1) the principal amount of an original issue discount debt security that
      will be deemed to be outstanding will be the amount of the principal
      that would be due and payable as of the date of the determination upon
      acceleration of the maturity thereof,

  (2) the principal amount of a debt security denominated in a foreign
      currency or currency unit will be the U.S. dollar equivalent,
      determined as of the date of original issuance of that debt security,
      of the principal amount of that debt security or, in the case of an
      original issue discount debt security, the U.S. dollar equivalent,
      determined as of the date of original issuance of that debt security,
      of the amount determined as provided in (1) above and

  (3) any debt security owned by CSX or any other obligor on that debt
      security or any affiliate of CSX or other obligor will be deemed not to
      be outstanding.

  Each indenture contains provisions for convening meetings of the holders of
debt securities of any or all series. A meeting may be called at any time by
the relevant trustee, and also, upon request, by CSX or the holders of at least
10% in aggregate principal amount of the outstanding debt securities of that
series, in each case upon notice given in accordance with "Notices" below and
the provisions of the indenture. Except for any consent which must be given by
the holder of each outstanding debt security that would be affected as
described above, any resolution presented at a meeting, or adjourned meeting
duly reconvened, at which a quorum (as described below) is present may be
adopted by the affirmative vote of the holders of a majority in principal
amount of the outstanding debt securities of that series; provided, however,
that, except for any consent which must be given by the holder of each
outstanding debt security that would be affected, as described above, any
resolution with respect to any consent, waiver, request, demand, notice,
authorization, direction or other action which may be given by the holders of
not less than a specified percentage in principal amount of the outstanding
debt securities of a series may be adopted at a meeting, or an adjourned
meeting duly reconvened, at which a quorum is present only by the affirmative
vote of the holders of not less than the specified percentage in principal
amount of the outstanding debt securities of that series.

  Any resolution passed or decision taken at any meeting of holders of debt
securities of any series duly held in accordance with the relevant indenture
will be binding on all holders of debt

                                       16


securities of that series and the related coupons. The quorum required for any
meeting called to adopt a resolution, and at any reconvened meeting, will be
persons holding or representing a majority in principal amount of the
outstanding debt securities of a series; provided, however, that if any action
is to be taken at that meeting with respect to a consent, waiver, request,
demand, notice, authorization, direction or other action which may be given by
the holders of not less than a specified percentage in principal amount of the
outstanding debt securities of a series, the persons holding or representing
that specified percentage in principal amount of the outstanding debt
securities of the series will constitute a quorum.

Notices

  Except as otherwise provided in the indenture, notices to holders of bearer
debt securities will be given by publication at least twice in a daily
newspaper of general circulation in The City of New York and in any other city
or cities as may be specified in those debt securities. Notices to holders of
registered debt securities will be given by mail to the addresses of those
holders as they appear in the security register.

Title

  Title to any bearer debt securities (including bearer debt securities in
temporary global form and in permanent global form) and any related coupons
will pass by delivery. CSX, the trustee and any agent of CSX or the trustee may
treat the bearer of any bearer debt security and the bearer of any coupon and
the registered owner of any registered debt security as the absolute owner
(whether or not that debt security or coupon is overdue and notwithstanding any
notice to the contrary) for the purpose of making payment and for all other
purposes.

Replacement of Debt Securities

  Any mutilated debt security or a debt security with a mutilated coupon will
be replaced by CSX at the expense of the holder upon surrender of that debt
security to the relevant trustee. Debt securities or coupons that become
destroyed, lost or stolen will be replaced by CSX at the expense of the holder
upon delivery to the relevant trustee of evidence of the destruction, loss or
theft satisfactory to CSX and the relevant trustee; in the case of any coupon
which becomes destroyed, lost or stolen, that coupon will be replaced by
issuance of a new debt security in exchange for the debt security to which the
coupon appertains. In the case of a destroyed, lost or stolen debt security or
coupon, an indemnity satisfactory to the trustee and CSX may be required at the
expense of the holder of that debt security or coupon before a replacement debt
security will be issued.

Discharge, Defeasance and Covenant Defeasance

  Upon the direction of CSX, either indenture will generally cease to be of
further effect with respect to any series of debt securities issued under that
indenture specified by CSX (subject to the survival of certain provisions of
that indenture) when

  .  CSX has delivered to the relevant trustee for cancellation all debt
     securities issued under that indenture or

  .  all debt securities issued under that indenture not previously delivered
     to the relevant trustee for cancellation have become due and payable, or
     are by their terms to become due and payable within one year or are to
     be called for redemption within one year, and CSX has deposited with the
     relevant trustee as trust funds the entire amount sufficient to pay and
     discharge at stated maturity or upon redemption the entire indebtedness
     on all debt securities issued under that indenture (and if, in either
     case, CSX has paid or caused to be paid all other sums payable under the
     relevant indenture with respect to the debt securities of that series by
     CSX and CSX has delivered an officer's certificate and an opinion of
     counsel each stating that the requisite conditions have been complied
     with).

                                       17


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

  (1) to defease and be discharged from any and all obligations with respect
      to those debt securities (except as otherwise provided in the relevant
      indenture) ("defeasance") or

  (2) to be released from our obligations with respect to those debt
      securities described above under "--Certain Covenants and Agreements of
      CSX--Covenant in the Senior Indenture--Limitation on Liens on Stock of
      Our Principal Subsidiaries" (which covenant appears only in the senior
      indenture) and certain other restrictive covenants in the relevant
      indenture and, if indicated in the applicable prospectus supplement,
      our obligations with respect to any other covenant applicable to the
      debt securities of that series ("covenant defeasance").

  If we exercise our defeasance option with respect to any series of debt
securities, payment of those debt securities may not be accelerated because of
an event of default. If we exercise our covenant defeasance option with respect
to any series of debt securities, payment of those debt securities may not be
accelerated because of an event of default related to the covenants noted under
clause (2) of the immediately preceding paragraph. We may exercise our
defeasance option with respect to those debt securities even though we may have
previously exercised our covenant defeasance option.

  If CSX effects covenant defeasance with respect to any debt securities and
those debt securities are declared due and payable because of the occurrence of
any event of default other than an event of default with respect to the
covenant described above under "--Certain Covenants and Agreements of CSX--
Covenant in the Senior Indenture--Limitation on Liens on Stock of Our Principal
Subsidiaries" (which covenant appears only in the senior indenture and which
would no longer be applicable to those debt securities after the covenant
defeasance) or with respect to any other covenant as to which there has been
covenant defeasance, the amount of monies and/or government obligations
deposited with the applicable trustee to effect the covenant defeasance may not
be sufficient to pay amounts due on those debt securities at the time of any
acceleration resulting from the event of default. However, we would remain
liable to make payment of those amounts due at the time of acceleration.

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

  (1) CSX irrevocably deposits in trust with the trustee cash and/or U.S.
      government obligations for the payment of principal, premium, if any,
      and interest with respect to those debt securities to maturity or
      redemption, as the case may be, and we deliver to the relevant trustee
      a certificate from a nationally recognized firm of independent public
      accountants expressing their opinion that the payments of principal and
      interest when due and without reinvestment on the deposited U.S.
      government obligations plus any deposited money without investment will
      provide cash at the times and in the amounts as will be sufficient to
      pay the principal, premium, if any, and interest when due with respect
      to all those debt securities to maturity or redemption, as the case may
      be,

  (2) no event of default with respect to the debt securities of that series
      has occurred and is continuing

    .  on the date of the deposit or

    .  with respect to certain bankruptcy defaults, at any time during the
       period ending on the 123rd day after the date of the deposit,

  (3) the defeasance or covenant defeasance does not result in the trust
      arising from that deposit to constitute, unless it is qualified as, a
      regulated investment company under the Investment Company Act of 1940,
      as amended,

                                       18


  (4) the defeasance or covenant defeasance does not result in a breach or
      violation of, or constitute a default under, the relevant indenture or
      any other agreement or instrument to which we are a party or by which
      we are bound,

  (5) CSX delivers to the trustee an opinion of counsel to the effect that
      the holders of the debt securities will not recognize income, gain or
      loss for United States federal income tax purposes as a result of the
      defeasance or covenant defeasance and will be subject to United States
      federal income tax on the same amounts, in the same manner and at the
      same times as would have been the case if the defeasance or covenant
      defeasance had not occurred, and

  (6) CSX delivers to the trustee an officer's certificate and an opinion of
      counsel, each stating that all conditions precedent to the defeasance
      and discharge of the debt securities as contemplated by the indenture
      have been complied with.

  The opinion of counsel, with respect to defeasance, referred to in clause (5)
above, must refer to and be based upon a ruling of the Internal Revenue Service
or a change in applicable United States federal income tax law occurring after
the date of the relevant indenture.

  The trustee must hold in trust cash or U.S. government obligations deposited
with it as described above and must apply the deposited cash and the proceeds
from deposited U.S. government obligations to the payment of principal,
premium, if any, and interest with respect to the debt securities.

  The applicable prospectus supplement may further describe the provisions, if
any, permitting or restricting defeasance or covenant defeasance with respect
to the debt securities of a particular series.

Governing Law

  The indentures and the debt securities will be governed by, and construed in
accordance with, the laws of the State of New York.

Concerning the Trustees

  The Trust Indenture Act of 1939 contains limitations on the rights of a
trustee, should it become a creditor of CSX, to obtain payment of claims in
certain cases or to realize on certain property received by it in respect of
those claims, as security or otherwise. Each trustee is permitted to engage in
other transactions with CSX and our subsidiaries from time to time, provided
that if the trustee acquires any conflicting interest it must eliminate the
conflict upon the occurrence of an event of default under the relevant
indenture, or else resign.

  CSX and certain of our subsidiaries may from time to time maintain lines of
credit, and have other customary banking and commercial relationships, with The
Chase Manhattan Bank, the senior trustee and the subordinated trustee. The

Subordination of Subordinated Debt Securities

  The payment of the principal of, premium, if any, and interest, if any, on
the subordinated debt securities will be subordinated, to the extent and in the
manner set forth in the subordinated

                                       19


indenture, in right of payment to the prior payment in full of all senior
indebtedness which may at any time and from time to time be outstanding. Unless
otherwise provided in the applicable prospectus supplement with respect to an
issue of subordinated debt securities, in the event of any distribution of our
assets upon any dissolution, winding up, liquidation, reorganization or other
similar proceedings of CSX,

  .  all senior indebtedness shall first be paid in full, or that payment
     shall be provided for, before any payment on account of the principal
     of, or premium, if any, or interest, if any, on the subordinated debt
     securities is made and

  .  if any payment or distribution of our assets is received by the
     subordinated trustee or the holders of any of the subordinated debt
     securities before all senior indebtedness is paid in full, that payment
     or distribution will be paid over to the holders of senior indebtedness
     or on their behalf for application to the payment of all senior
     indebtedness remaining unpaid until all senior indebtedness has been
     paid in full or that payment provided for, after giving effect to any
     concurrent payment or distribution to the holders of senior
     indebtedness.

  Subject to the payment in full of all senior indebtedness upon any
distribution of our assets, the holders of the subordinated debt securities
will be subrogated to the rights of the holders of the senior indebtedness to
the extent of payments made to the holders of senior indebtedness out of the
distributive share of the subordinated debt securities.

  By reason of subordination of the subordinated debt securities, if there is
any distribution of our assets upon dissolution, winding up, liquidation,
reorganization or other similar proceedings of CSX,

  .  holders of senior indebtedness will be entitled to be paid in full
     before payments may be made on the subordinated debt securities and the
     holders of subordinated debt securities will be required to pay over
     their share of that distribution to the holders of senior indebtedness
     until all senior indebtedness is paid in full and

  .  creditors of CSX who are neither holders of subordinated debt securities
     nor holders of senior indebtedness may recover less, ratably, than
     holders of senior indebtedness and may recover more, ratably, than the
     holders of the subordinated debt securities.

Furthermore, subordination may result in a reduction or elimination of payments
to the holders of subordinated debt securities. The subordinated indenture
provides that the subordination provisions in the subordinated indenture will
not apply to any money and securities held in trust pursuant to the discharge,
defeasance and covenant defeasance provisions of the subordinated indenture
(see "--Discharge, Defeasance and Covenant Defeasance" above).

  The subordinated indenture also provides that no payment on account of the
principal of, or premium, if any, sinking funds, if any, or interest, if any,
on the subordinated debt securities will be made unless full payment of amounts
then due for the principal of, premium, if any, sinking funds, if any, and
interest, if any, on senior indebtedness has been made or duly provided for.

  The subordinated indenture defines "senior indebtedness" as

  (1) any liability of CSX

    .  for borrowed money or under any reimbursement obligation relating to
       a letter of credit, or

    .  evidenced by a bond, note, debenture or similar instrument, or

    .  for obligations to pay the deferred purchase price of property or
       services, except trade accounts payable arising in the ordinary
       course of business, or

                                       20


    .  for the payment of money relating to a capitalized lease obligation,
       or

    .  for the payment of money under any swap agreement;

  (2) any liability of others described in the preceding clause (1) that CSX
      has guaranteed or that is otherwise our legal liability; and

  (3) any deferral, renewal, extension or refunding of any liability of the
      types referred to in clauses (1) and (2) above,

unless, in the instrument creating or evidencing any liability referred to in
clause (1) or (2) above or any deferral, renewal, extension or refunding
referred to in clause (3) above or pursuant to which the same is outstanding,
it is expressly provided that the liability, deferral, renewal, extension or
refunding is subordinate in right of payment to all other indebtedness of CSX
or is not senior or prior in right of payment to the subordinated debt
securities or ranks pari passu with or subordinate to the subordinated debt
securities in right of payment; and provided that the subordinated debt
securities shall not constitute senior indebtedness. The subordinated indenture
defines "swap agreement" as any financial agreement designed to manage our
exposure to fluctuations in interest rates, currency exchange rates or
commodity prices, including without limitation swap agreements, option
agreements, cap agreements, floor agreements, collar agreements and forward
purchase agreements.

  If this prospectus is being delivered in connection with the offering of a
series of subordinated debt securities, the accompanying prospectus supplement
or the information incorporated by reference in this prospectus will set forth
the approximate amount of senior indebtedness outstanding as of a recent date.
There are no limitations in the subordinated indenture on the issuance or
incurrence of senior indebtedness of CSX.

                          DESCRIPTION OF CAPITAL STOCK

  As of the date of this prospectus, the authorized capital stock of CSX is (i)
300,000,000 shares of common stock, par value $1.00 per share, and (ii)
25,000,000 shares of preferred stock, without par value, issuable in series, of
which 3,000,000 shares of Series B Preferred Stock were reserved for issuance
under the Shareholders Rights Plan. As of December 29, 2000, 212,737,613 shares
of common stock were issued and outstanding, and no shares of preferred stock
were outstanding.

  The following summary of certain provisions of common stock, preferred stock,
Series B Preferred Stock, the Amended and Restated Articles of Incorporation
and the By-laws of CSX do not purport to be complete and are qualified in their
entirety by reference to the Amended and Restated Articles of Incorporation and
the By-laws, copies of which have been incorporated by reference or filed as
exhibits to the registration statement.

Common Stock

  CSX may issue (either separately or together with other securities) shares of
common stock. If we offer common stock, the specific terms of the offering,
including the number of shares offered and the initial public offering price,
will be described in the applicable prospectus supplement.

  CSX common stock is listed on the New York Stock Exchange under the symbol
"CSX." All outstanding shares of common stock are fully-paid and non-
assessable. Any additional shares of common stock we issue will also be fully-
paid and non-assessable. Holders of common stock are entitled to one vote per
share on all matters voted on by shareholders, including elections of
directors, and, except as otherwise required by law or provided by the express
provisions of any series of preferred stock, the holders of those shares
exclusively possess all voting power of CSX. If

                                       21


and when issued and except as otherwise provided by law, the holders of Series
B Preferred Stock will be entitled to 100 votes per share (subject to
adjustment in accordance with the Amended and Restated Articles of
Incorporation) on all matters submitted to a vote of CSX shareholders, and the
holders of Series B Preferred Stock and the holders of common stock and any
other class of stock of CSX then having general voting rights will vote
together as one class. See "--Preferred Stock" and "--Series B Preferred Stock
Reserved for Issuance" below. There is no cumulative voting in the election of
directors, and no holder of common stock is entitled as such, as a matter of
right, to subscribe for or purchase any shares of common stock or preferred
stock. Subject to the preferential rights of any outstanding series of
preferred stock, the holders of common stock are entitled to receive ratably
dividends as may be declared from time to time by our Board of Directors from
funds legally available for that purpose. In the event of a liquidation,
dissolution or winding up of CSX, holders of common stock are entitled to share
ratably in all assets remaining after payment or provision for liabilities and
amounts owing in respect of any outstanding preferred stock.

  The transfer agent for CSX common stock is Harris Trust Company located in
Chicago, Illinois.

Preferred Stock

  CSX may issue shares of our preferred stock, in one or more series, either
separately, or together with, or upon the conversion of or in exchange for,
other securities.

  The following description of preferred stock sets forth certain general terms
and provisions of any series of preferred stock to which any prospectus
supplement may relate. If we offer preferred stock, the terms of any particular
series of preferred stock, including preferred stock to be represented by
depositary shares, will be described in the applicable prospectus supplement,
including (where applicable):

  .  the title of the series;

  .  the number of shares offered;

  .  the initial public offering price;

  .  the dividend rate or method of calculation of the dividend rate and the
     dividend payment dates or periods;

  .  the date from which dividends will accrue and whether dividends will be
     cumulative;

  .  any right to vote with holders of shares of any other series or class
     and any right to vote as a class;

  .  the provisions for redemption or repurchase, if applicable, including
     any sinking fund provisions for the redemption or repurchase of shares;

  .  the amount payable with respect to both the payment of dividends and the
     distribution of assets upon liquidation, dissolution or winding up of
     CSX;

  .  any listing on any securities exchange;

  .  the procedures for any auction or remarketing, if any;

  .  the terms and conditions, if any, upon which the preferred stock will be
     convertible into or exchangeable for other securities;

  .  whether interests will be represented by depositary shares; and

  .  any other specific terms of the offered preferred stock.

  The form of articles of amendment relating to a series of offered preferred
stock will be filed as an exhibit to or incorporated by reference in the
registration statement. The terms of the preferred

                                       22


stock offered under any prospectus supplement may differ from the general terms
set forth in this prospectus.

  Preferred stock may be issued from time to time in one or more series.
Subject to limitations prescribed by Virginia law and the Amended and Restated
Articles of Incorporation, our Board of Directors, without further action by
the shareholders, is authorized to designate and issue in series preferred
stock and to fix as to any series:

  .  the number of shares constituting that series,

  .  the rate of dividend, the time of payment and, if cumulative, the dates
     from which dividends will be cumulative, and the extent of participation
     rights, if any,

  .  any right to vote with holders of shares of any other series or class
     and any right to vote as a class, either generally or as a condition to
     specified corporate action,

  .  the price at and the terms and conditions on which shares may be
     redeemed, including any sinking fund provisions for the redemption or
     purchase of shares,

  .  the amount payable in the event of a liquidation, and

  .  whether shares will have the privilege of conversion, and if so, the
     terms and conditions on which shares may be converted.

  The issuance of preferred stock, while providing flexibility in connection
with possible acquisitions and other corporate purposes, could, among other
things, adversely affect the voting power of the holders of common stock and,
under certain circumstances, make it more difficult for a third party to gain
control of CSX or remove present management and could have the effect of
delaying or preventing a merger, tender offer or other attempted takeover of
CSX. No holder of preferred stock will be entitled, as a matter of right, to
subscribe for or purchase any shares of preferred stock or common stock.

  Preferred stock will, when issued, be fully-paid and non-assessable. Unless
otherwise specified in the applicable prospectus supplement, any series of
offered preferred stock will rank, with respect to dividends and the
distribution of assets, senior to Series B Preferred Stock, if issued, and
common stock, and on a parity with shares of any other outstanding series of
preferred stock. Therefore, the Rights (described below) and any preferred
stock that may subsequently be issued may limit the rights of the holders of
our common stock and preferred stock. In addition, under certain circumstance,
preferred stock could also restrict dividend payments to our holders of common
stock.

  The transfer agent and registrar for a series of preferred stock will be
named in the applicable prospectus supplement.

Series B Preferred Stock Reserved for Issuance

  In connection with the issuance of the Rights (described under "--Shareholder
Rights Plan" below), our Board of Directors designated 3,000,000 shares of
preferred stock as Series B Preferred Stock. No shares of Series B Preferred
Stock are outstanding as of the date of this prospectus, and shares of Series B
Preferred Stock will be issued only in connection with the exercise of Rights.

  Subject to the rights of the holders of shares of any other series of
preferred stock ranking prior and superior to Series B Preferred Stock with
respect to dividends, and in preference to common stock or any other junior
series of preferred stock or other stock, each share of Series B Preferred
Stock is generally entitled to receive, when, as and if declared by our Board
of Directors out of funds legally available for that purpose, cumulative
quarterly cash dividends equal to the greater of $1.00 per share or, subject to
certain adjustments, 100 times the aggregate per share amount of all cash

                                       23


dividends and non-cash dividends paid on each share of CSX's common stock in
the preceding quarter. Whenever quarterly dividends or other distributions
payable to the holders of Series B Preferred Stock are in arrears, whether or
not those dividends or other distributions have been declared, CSX cannot

  .  declare or pay dividends or distributions to holders of common stock or
     any shares of stock junior to Series B Preferred Stock or

  .  purchase or otherwise acquire shares of Series B Preferred Stock or any
     shares of stock junior to or on parity with Series B Preferred Stock.

  Except as otherwise provided by law, holders of shares of Series B Preferred
Stock are entitled to 100 votes for each share held, and the shares of Series B
Preferred Stock and the shares of common stock of CSX will vote together as one
class. In the event CSX declares or pays any dividend to holders of common
stock payable in common stock, or affects the number of outstanding shares of
common stock by reclassification or otherwise, the number of votes per share of
Series B Preferred Stock will be adjusted to equalize the relative voting
strength of the Series B Preferred Stock vis-a-vis the common stock to the
relative voting strength immediately prior to that event.

  Upon any involuntary or voluntary liquidation, dissolution or winding up of
CSX, subject to the rights of any other capital stock prior in rank with
respect to liquidation, dissolution or winding up, the holders of Series B
Preferred Stock will be entitled to be paid out of the assets of CSX legally
available for that purpose the greater of $100 per share, plus accumulated and
unpaid dividends, or an amount per share equal to 100 times the aggregate
amount to be distributed per share to the holders of common stock (subject to
certain adjustments). In that liquidation, dissolution or winding up, Series B
Preferred Stock will be paid prior to any distributions to the holders of
common stock or any other stock ranking junior to Series B Preferred Stock.
Holders of stock ranking on a parity (either as to dividends or liquidation,
dissolution or winding up) with Series B Preferred Stock, will share ratably in
any distribution with holders of Series B Preferred Stock in proportion to the
total amounts to which the holders of all those shares are entitled upon
liquidation, dissolution or winding up of CSX.

  In the event that CSX enters into any consolidation, merger, combination or
other transaction in which common stock is exchanged for or changed into other
securities, cash or property, the holders of Series B Preferred Stock will be
entitled to receive 100 times the per share consideration received in
connection with that transaction by holders of common stock (subject to certain
adjustments).

  Shares of Series B Preferred Stock which have been acquired by CSX in any
manner whatsoever will not be reissued as Series B Preferred Stock, but will be
retired and cancelled in the manner provided by Virginia law and will
constitute authorized but unissued preferred stock undesignated as to series.
Shares of Series B Preferred Stock are not redeemable.

Shareholder Rights Plan

  The following summary of certain provisions of CSX's Shareholder Rights Plan
and the Rights Agreement, dated as of May 29, 1998 as amended by Amendment No.
1 dated as of June 27, 2000 (the "Rights Agreement"), between CSX and Harris
Trust Company of New York does not purport to be complete and is qualified in
its entirety by reference to the Rights Agreement, including the form of Rights
certificate attached to the Rights Agreement, and the articles of amendment for
Series B Preferred Stock, both of which are incorporated by reference as
exhibits to the registration statement.

  The Rights Agreement contains provisions that could make it more difficult
for a third party to gain control of CSX and that could have the effect of
delaying or preventing a merger, tender offer or other takeover attempt of CSX.
In May 1998, the Board of Directors of CSX declared a dividend of one preferred
share purchase right (each, a "Right") for each share of common stock
outstanding as

                                       24


of June 8, 1998. Each Right entitles its holder to purchase from CSX, until the
earliest of June 8, 2008, or the redemption or exchange of the Rights, one one-
hundredth (1/100th) of a share of Series B Preferred Stock at an exercise price
of $180 per Right, subject to certain adjustments or, under certain
circumstances, to obtain additional shares of common stock of CSX in exchange
for each Right. The Rights will not be exercisable or transferable apart from
common stock of CSX until the earlier of 10 days following the public
announcement that a person or affiliated group has acquired or obtained the
right to acquire 10% or more of the outstanding common stock of CSX; or 10 days
following the commencement or announcement of an intention to make a tender
offer or exchange offer, the consummation of which would result in the
ownership by a person or group of 10% or more of the outstanding common stock
of CSX. Our Board of Directors may redeem the Rights at a price of one cent per
Right at any time prior to the acquisition by a person of 10% or more of the
outstanding common stock of CSX.

Virginia Stock Corporation Act; Anti-takeover Effects

  The Virginia Stock Corporation Act contains provisions governing "Affiliated
Transactions." These provisions, with several exceptions discussed below,
generally require approval of certain material transactions between a Virginia
corporation and any beneficial holder of more than 10% of any class of its
outstanding voting shares (an "Interested Shareholder") by a majority of
disinterested directors and by the holders of at least two-thirds of the
remaining voting shares. Affiliated Transactions subject to this approval
requirement include mergers, share exchanges, material dispositions of
corporate assets not in the ordinary course of business, any dissolution of the
corporation proposed by or on behalf of an Interested Shareholder, or any
reclassification, including reverse stock splits, recapitalization or merger of
the corporation with its subsidiaries, which increases the percentage of voting
shares owned beneficially by an Interested Shareholder by more than 5%.

  For three years following the time that an Interested Shareholder becomes an
owner of 10% of the outstanding voting shares, a Virginia corporation cannot
engage in an Affiliated Transaction with that Interested Shareholder without
the approval of two-thirds of the voting shares other than those shares
beneficially owned by the Interested Shareholder, and the approval of a
majority of the Disinterested Directors. "Disinterested Director" means, with
respect to a particular Interested Shareholder, a member of our Board of
Directors who was

  .  a member on the date on which an Interested Shareholder became an
     Interested Shareholder or

  .  recommended for election by, or was elected to fill a vacancy and
     received the affirmative vote of, a majority of the Disinterested
     Directors then on the Board.

After the expiration of the three-year period, the statute requires approval of
Affiliated Transactions by two-thirds of the voting shares other than those
beneficially owned by the Interested Shareholder.

  The principal exceptions to the special voting requirements apply to
transactions proposed after the three-year period has expired and require
either that the transaction be approved by a majority of CSX's Disinterested
Directors or that the transaction satisfy the fair-price requirements of the
statute. In general, the fair-price requirement provides that in a two-step
acquisition transaction, the Interested Shareholder must pay the shareholders
in the second step either the same amount of cash or the same amount and type
of consideration paid to acquire CSX's shares in the first step.

  None of the limitations and special voting requirements described above
applies to an Interested Shareholder whose acquisition of shares making that
person an Interested Shareholder was approved by a majority of CSX's
Disinterested Directors.

  These provisions are designed to deter certain types of takeovers of Virginia
corporations. The statute provides that, by affirmative vote of a majority of
the voting shares other than shares owned

                                       25


by any Interested Shareholder, a corporation can adopt an amendment to its
articles of incorporation or by-laws providing that the Affiliated Transactions
provisions shall not apply to the corporation. CSX has not "opted out" of the
Affiliated Transactions provisions.

  Virginia law also generally provides that shares of a Virginia corporation
acquired in a transaction that would cause the acquiring person's voting
strength to meet or exceed any of three thresholds (20%, 33 1/3% or 50%) have
no voting rights with respect to those shares unless granted by a majority vote
of shares not owned by the acquiring person or any officer or employee-director
of the corporation. This provision empowers an acquiring person to require the
Virginia corporation to hold a special meeting of shareholders to consider the
matter within 50 days of its request. The Board of Directors of a Virginia
corporation can opt out of this provision at any time before four days after
receipt of a control share acquisition notice.

                        DESCRIPTION OF DEPOSITARY SHARES

  CSX may offer depositary shares (either separately or together with other
securities) representing fractional interests in shares of our preferred stock
of any series. In connection with the issuance of any depositary shares, CSX
will enter into a deposit agreement with a bank or trust company, as
depositary, which will be named in the applicable prospectus supplement.
Depositary shares will be evidenced by depositary receipts issued pursuant to
the related deposit agreement. Immediately following the issuance by CSX of the
preferred stock related to the depositary shares, we will deposit the shares of
preferred stock with the relevant preferred stock depositary and will cause the
preferred stock depositary to issue, on our behalf, the related depositary
receipts. Subject to the terms of the deposit agreement, each owner of a
depositary receipt will be entitled, in proportion to the fraction of a share
of preferred stock represented by the related depositary share, to all the
rights, preferences and privileges of, and will be subject to all of the
limitations and restrictions on, the preferred stock represented by the
depositary receipt (including, if applicable, dividend, voting, conversion,
exchange, redemption and liquidation rights).

  The form of deposit agreement, together with the form of related depositary
receipt, that will be entered into with respect to a particular offering of
depositary shares will be filed as an exhibit to or incorporated by reference
in the registration statement.

  The applicable prospectus supplement will describe the terms of the
depositary shares and the related deposit agreement for a particular issue of
depositary shares, which terms may include the following if applicable to those
depositary shares:

  .  the terms of the series of preferred stock deposited by CSX under the
     related deposit agreement;

  .  the number of depositary shares and the fraction of one share of
     preferred stock represented by one depositary share;

  .  whether the depositary shares will be listed on any securities exchange;

  .  whether the depositary shares will be sold with any other securities
     and, if so, the amount and terms of those securities; and

  .  any other specific terms of the depositary shares and the related
     deposit agreement.

                                       26


                       DESCRIPTION OF SECURITIES WARRANTS

  CSX may issue, either separately or together with other securities,
securities warrants for the purchase of debt securities, preferred stock or
common stock. Each securities warrant will entitle the holder to purchase the
principal amount of debt securities or number of shares of preferred stock or
common stock, as the case may be, at the exercise price and in the manner
specified in the prospectus supplement relating to those securities warrants.
Securities warrants may be exercised at any time up to the date and time
specified in the applicable prospectus supplement.

  Securities warrants will be issued under one or more warrant agreements to be
entered into between CSX and a bank or trust company, as warrant agent. The
material terms and provisions of the warrant agreement for a particular issue
of securities warrants will be set forth in the applicable prospectus
supplement. The form of securities warrant agreement, including the form of
certificates representing the securities warrants, that will be entered into
with respect to a particular offering of securities warrants will be filed as
an exhibit to or incorporated by reference in the registration statement.

  The applicable prospectus supplement will describe the terms of the
securities warrants for a particular issue of securities warrants, which terms
may include the following if applicable to those securities warrants:

  .  the title and aggregate number of the securities warrants;

  .  the designation, aggregate principal amount, currency, currencies or
     currency units and terms of the debt securities purchasable upon
     exercise of the securities warrants; the price, or the manner of
     determining the price, at which the debt securities may be purchased
     upon exercise of the securities warrants;

  .  the designation, number of shares and terms of the series of preferred
     stock purchasable upon exercise of the securities warrants; the price,
     or the manner of determining the price, at which the preferred stock may
     be purchased upon exercise of the securities warrants;

  .  the number of shares of common stock that may be purchased upon exercise
     of each securities warrant; the price, or the manner of determining the
     price, at which the shares may be purchased upon the exercise of the
     securities warrants;

  .  if other than cash, the property and manner in which the exercise price
     of the securities warrants may be paid; and any minimum number of
     securities warrants that may be exercisable at any one time;

  .  the time or times at which, or period or periods during which, the
     securities warrants may be exercised and the expiration date of the
     securities warrants;

  .  the terms of any right of CSX to redeem the securities warrants;

  .  the terms of any right of CSX to accelerate the exercise of the
     securities warrants upon the occurrence of certain events;

  .  whether the securities warrants will be sold with any other securities,
     and the date, if any, on and after which the securities warrants and the
     other securities will be separately transferable;

  .  whether the securities warrants will be issued in registered or bearer
     form;

  .  a discussion of certain material Federal income tax, accounting and
     other special considerations, procedures and limitations relating to the
     securities warrants; and

  .  any other terms of the securities warrants.


                                       27


                              PLAN OF DISTRIBUTION

  CSX may sell securities to one or more underwriters for public offering and
sale by them or may sell securities to institutional investors directly or
through agents who solicit or receive offers on our behalf or through dealers
or through a combination of any these methods of sale. The prospectus
supplement with respect to particular securities will set forth the terms of
the offering of those securities, including the name or names of any
underwriters or agents, the public offering or purchase price and the proceeds
to CSX from that sale, the expenses of the offering, any discounts and
commissions to be allowed or paid to the underwriters or agents, all other
items constituting underwriting compensation, the discounts and commissions to
be allowed or paid to dealers, if any, and the securities exchanges, if any, on
which the securities will be listed.

  Underwriters may offer and sell the securities at a fixed price or prices,
which may be changed, or from time to time at market prices prevailing at the
time of sale, at prices related to prevailing market prices or at negotiated
prices. We also may offer and sell securities in exchange for one or more of
our outstanding issues of debt. We may, from time to time, authorize agents
acting on a best or reasonable efforts basis as our agents to solicit or
receive offers to purchase the securities upon the terms and conditions as are
set forth in the applicable prospectus supplement. In connection with the sale
of securities, underwriters or agents may be deemed to have received
compensation from CSX in the form of underwriting discounts or commissions and
may also receive commissions from purchasers of securities for whom they may
act as agent. Underwriters may sell securities to or through dealers, and
dealers may receive compensation in the form of discounts, concessions or
commissions from the underwriters and/or commissions from the purchasers for
whom they may act as agent.

  Underwriters, dealers and agents who participate in the distribution of
securities and their controlling persons may be entitled, under agreements
which may be entered into with CSX, to indemnification by us against certain
liabilities, including liabilities under the Securities Act, or to contribution
with respect to payments which the underwriters, dealers or agents and their
controlling persons may be required to make in respect of those liabilities.

  If so indicated in the applicable prospectus supplement, CSX may authorize
underwriters or other persons acting as our agents to solicit offers by certain
institutions to purchase securities from us pursuant to contracts providing for
payment and delivery on a future date. Institutions with which those contracts
may be made include commercial and savings banks, insurance companies, pension
funds, investment companies, educational and charitable institutions and
others, but in all cases those institutions must be approved by us. The
obligations of any institutional purchaser under those contracts will not be
subject to any conditions except

  .  the purchase by that institution of the securities covered by the
     contract will not at the time of delivery be prohibited under the laws
     of the jurisdiction to which that institution is subject, and

  .  if the securities are being sold to underwriters, we will have sold to
     the underwriters the total principal amount of the securities less the
     principal amount covered by delayed delivery contracts.

  Each series of offered securities other than common stock will be a new issue
of securities with no established trading market. Any underwriters to whom
offered securities are sold by CSX for public offering and sale may make a
market in such offered securities, but the underwriters will not be obligated
to do so and may discontinue any market making at any time without notice. No
assurance can be given as to the liquidity of the trading market for any
offered securities.

  Any underwriter may engage in stabilizing and syndicate covering transactions
in accordance with Rule 104 under the Exchange Act. Rule 104 permits
stabilizing bids to purchase the underlying security so long as the stabilizing
bids to do not exceed a specified maximum. The underwriters may over-allot
offered securities, thereby creating a short position in the underwriters'
account. Syndicate covering transactions involve purchases of offered
securities in the open market after the distribution has been completed to
cover syndicate short positions. Stabilizing and syndicate covering
transactions may cause the price of the offered securities to be higher than it
would otherwise be in the absence of such transactions. These transactions, if
commenced, may be discontinued at any time.

  Certain of the underwriters, dealers or agents and their affiliates may
engage in transactions with and perform services for CSX in the ordinary course
of business.
