     This security (the "Security") is one of a duly authorized issue of
securities (herein called the "Securities") of CSX Corporation, a Virginia
corporation (hereinafter called the "Company," which term includes any successor
corporation under the Indenture hereinafter referred to), issued and to be
issued in one or more series under an indenture, unlimited as to aggregate
principal amount, dated as of August 1, 1990 between the Company and The Chase
Manhattan Bank, Trustee (herein called the "Trustee," which term includes any
successor trustee under the Indenture (as hereinafter defined)), 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, to which indenture and all indentures
supplemental thereto (the indenture, as supplemented being herein called the
"Indenture") reference is hereby made for a statement of the respective rights
thereunder of the Company, the Trustee and the Holders of the Securities and of
the terms upon which the Securities are, and are to be, authenticated and
delivered. This Security is one of the series designated on the face hereof,
which series has been issued in an aggregate initial principal amount of
$400,000,000 (FOUR HUNDRED MILLION DOLLARS). 

 
                                       2

This Security represents an aggregate initial principal amount of $200,000,000
(TWO HUNDRED MILLION DOLLARS) (as adjusted from time to time in accordance with
the terms and provisions hereof and as set forth on Exhibit A hereto, the
"Principal Amount") of the Securities of such series, with the Interest Payment
Dates, date of original issuance, and date of Maturity specified herein and
bearing interest on said Principal Amount at the interest rate specified herein.

     The Company, for value received, hereby promises to pay CEDE & CO., or its
registered assigns, the principal sum of $200,000,000 (TWO HUNDRED MILLION
DOLLARS) on October 15, 2008 and to pay interest (computed on the basis of a
360-day year of twelve 30-day months) thereon from October 28, 1998 or from the
most recent Interest Payment Date to which interest has been paid or duly
provided for, or, if the date of this Security is an Interest Payment Date to
which interest has been paid or duly provided for, then from the date hereof,
semiannually in arrears on April 15 and October 15 in each year, commencing
April 15, 1999, and at Maturity at the rate of 6.25% per annum, until the
principal hereof is paid or duly made available for payment.  The Company shall
pay interest on overdue principal and premium, if any, and (to the extent
lawful) interest on overdue installments of interest at the rate per annum borne
by the Security.  The interest so payable, and punctually paid or duly provided
for, on any Interest Payment Date will, as provided in such Indenture, be paid
to the Person in whose name this Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest, which shall be the April 15 or October 15 (whether or not a
Business Day), as the case may be, next preceding such Interest Payment Date.
Except as otherwise provided in the Indenture, any such interest not so
punctually paid or duly provided for shall forthwith cease to be payable to the
Holder on such Regular Record Date and may be paid to the Person in whose name
this Security (or one or more Predecessor Securities) is registered at the close
of business on a Special Record Date to be fixed by the Trustee for the payment
of such Defaulted Interest, notice whereof shall be given to the Holder of this
Security not less than 10 days prior to such Special Record Date, or may be paid
at any time in any other lawful manner not inconsistent with the requirements of
any securities exchange on which the Securities of this series may be listed,
and upon such notice as may be required by such exchange, all as more fully
provided in such Indenture.  Notwithstanding the foregoing, interest payable on
this Security at Maturity will be payable to the person to whom principal is
payable.

     This Security is exchangeable in whole or from time to time in part for
definitive Registered Securities of this series only as provided in this
paragraph.  If (x) the Depository with respect to the Securities of this series
(the "Depository") notifies the Company that it is unwilling, unable or
ineligible to continue as Depository for this Security or if at any time the
Depository ceases to be a clearing agency registered under the Securities
Exchange Act of 1934, as amended, (y) the Company in its sole discretion
determines that this Security shall be exchangeable for definitive Registered
Securities and executes and delivers to the Trustee a Company Order providing
that this Security shall be so exchangeable or (z) there shall have happened and
be continuing an Event of Default or any event which, after notice or lapse of
time, or both, would become an Event of Default with respect to the Securities
of the series of which this Security is a part, this Security or any portion
hereof shall, in the case of clause (x) above, be exchanged for definitive
Registered Securities of this series, and in the case of clauses (y) and (z)
above, be exchangeable for definitive 

 
                                       3

Registered Securities of this series, provided that the definitive Security so
issued in exchange for this Security shall be in authorized denominations and be
of like tenor and of an equal aggregate principal amount as the portion of the
Security to be exchanged, and provided further that, in the case of clauses (y)
and (z) above, definitive Registered Securities of this series will be issued in
exchange for this Security, or any portion hereof, only if such definitive
Registered Securities were requested by written notice to the Security Registrar
by or on behalf of a Person who is a beneficial owner of an interest herein
given through the Holder hereof. Any definitive Registered Security of this
series issued in exchange for this Security, or any portion hereof, shall be
registered in the name or names of such Person or Persons as the Holder hereof
shall instruct the Security Registrar. Except as provided above, owners of
beneficial interests in this Security will not be entitled to receive physical
delivery of Securities in definitive form and will not be considered the Holders
thereof for any purpose under the Indenture.

     Any exchange of this Security or portion hereof for one or more definitive
Registered Securities of this series will be made at the New York office of the
Security Registrar.  Upon exchange of any portion of this Security for one or
more definitive Registered Securities of this series, the Trustee shall endorse
Exhibit A of this Security to reflect the reduction of its Principal Amount by
an amount equal to the aggregate principal amount of the definitive Registered
Securities of this series so issued in exchange, whereupon the Principal Amount
hereof shall be reduced for all purposes by the amount so exchanged and noted.
Except as otherwise provided herein or in the Indenture, until exchanged in full
for one or more definitive Registered Securities of this series, this Security
shall in all respects be subject to and entitled to the same benefits and
conditions under the Indenture as a duly authenticated and delivered definitive
Registered Security of this series.

     The principal and any interest in respect of any portion of this Security
payable in respect of an Interest Payment Date or at the Stated Maturity
thereof, in each case occurring prior to the exchange of such portion for a
definitive Registered Security or Securities of this series, will be paid, as
provided herein, to the Holder hereof which will undertake in such circumstances
to credit any such principal and interest received by it in respect of this
Security to the respective accounts of the Persons who are the beneficial owners
of such interests on such Interest Payment Date or at Stated Maturity.  If a
definitive Registered Security or Registered Securities of this series are
issued in exchange for any portion of this Security after the close of business
at the office or agency where such exchange occurs on (i) any Regular Record
Date and before the opening of business at such office or agency on the relevant
Interest Payment Date, or (ii) any Special Record Date and before the opening of
business at such office or agency on the related proposed date for payment of
Defaulted Interest, then interest or Defaulted Interest, as the case may be,
will not be payable on such Interest Payment Date or proposed date for payment,
as the case may be, in respect of such Registered Security, but will be payable
on such Interest Payment Date or proposed date for payment, as the case may be,
only to the Holder hereof, and the Holder hereof will undertake in such
circumstances to credit such interest to the account or accounts of the Persons
who were the beneficial owners of such portion of this Security on such Regular
Record Date or Special Record Date, as the case may be.

 
                                       4

     Payment of the principal of and any such interest on this Security will be
made at the offices of The Chase Manhattan Bank, as Paying Agent, in the Borough
of Manhattan, The City of New York, or at such other office or agency of the
Company as may be designated by it for such purpose in the Borough of Manhattan,
The City of New York, in such coin or currency of the United States of America
as at the time of payment shall be legal tender for the payment of public and
private debts by check mailed to the registered Holders thereof; provided,
                                                                 -------- 
however, that at the option of the Holder, payment of interest may be made by
- -------                                                                      
wire transfer of immediately funds to an account of the Person entitled hereto
as such account shall be provided to the Security Registrar and shall appear in
the Security Register.

     If an Event of Default with respect to Securities of this series shall
occur and be continuing, the principal of the Securities of this series
(including this Security and the interests represented hereby) may be declared
due and payable in the manner and with the effect provided in the Indenture.
Upon payment (i) of the amount of principal so declared due and payable and (ii)
of interest on any overdue principal and overdue interest (in each case to the
extent that the payment of such interest shall be legally enforceable), all of
the Company's obligations in respect of the payment of the principal of and any
interest on the Securities of this series (including this Security and the
interests represented hereby) shall terminate.

     The Indenture contains provisions for defeasance at any time of (a) the
entire indebtedness of the Company on this Security and (b) certain restrictive
covenants and the related defaults and Events of Default, upon compliance with
certain conditions set forth therein, which provisions shall apply to this
Security.

     The provisions of Article Fourteen of the Indenture apply to Securities of
this series.

     The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities of each series to be
affected under the Indenture at any time by the Company and the Trustee with the
consent of the Holders of a majority in aggregate principal amount of the
Securities at the time Outstanding of each series affected thereby.  The
Indenture also contains provisions permitting the Holders of specified
percentages in aggregate principal amount of the Securities of each series at
the time Outstanding on behalf of the Holders of all Securities of such series
to waive compliance by the Company with certain provisions of the Indenture and
certain past defaults under the Indenture and their consequences.  Any such
consent or waiver by the Holder of this Security shall be conclusive and binding
upon such Holder and upon all future Holders of this Security  and the Persons
who are beneficial owners of interests represented hereby, and of any Security
issued in exchange herefor or in lieu hereof whether or not notation of such
consent or waiver is made upon this Security.

     As set forth in, and subject to, the provisions of the Indenture, no Holder
of any Security of this series will have any right to institute any proceeding
with respect to the Indenture or for any remedy thereunder, unless such Holder
shall have previously given to the Trustee written notice of a continuing Event
of Default with respect to the Securities of this series, the Holders of not
less 

 
                                       5

than 25% in aggregate principal amount of the Outstanding Securities of this
series shall have made written request, and offered reasonable indemnity, to the
Trustee to institute such proceeding as trustee, and the Trustee shall not have
received from the Holders of a majority in aggregate principal amount of the
Outstanding Securities of this series a direction inconsistent with such request
and shall have failed to institute such proceeding within 60 days; provided,
however, that such limitations do not apply to a suit instituted by the Holder
hereof for the enforcement of payment of the principal of (and premium, if any)
or interest on this Security on or after the respective due dates expressed
herein.

     No reference herein to the Indenture and no provision of this Security or
of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional to pay the principal of (and premium, if any) and
interest on this Security at the time, place and rate, and in the coin or
currency, herein prescribed.

     As provided in the Indenture and subject to certain limitations therein and
herein set forth, the transfer of Registered Securities of the series of which
this Security is a part may be registered on the Security Register of the
Company, upon surrender of such Securities for registration of transfer at the
office of the Security Registrar, duly endorsed by, or accompanied by a written
instrument of transfer in form satisfactory to the Company and the Security
Registrar duly executed by the Holder thereof or his attorney duly authorized in
writing, and thereupon one or two more new Securities of this Series and of like
tenor, of authorized denominations and for the same aggregate principal amount,
will be issued to the designated transferee or transferees.

     No service charge shall be made for any such registration of transfer or
exchange of Securities as provided above, but the Company may require payment of
a sum sufficient to cover any tax or other governmental charge payable in
connection therewith.

     Prior to due presentment of this Security for registration of transfer, the
Company, the Trustee and any agent of the Company or the Trustee may treat the
Person in whose name this Security is registered as the owner hereof for all
purposes, whether or not this Security be overdue, and neither the Company, the
Trustee nor any such agent shall be affected by notice to the contrary.

     The Securities of this series of which this Security is a part are issuable
only in registered form without coupons, in denominations of $1,000.00 and any
integral multiple thereof.  As provided in the Indenture and subject to certain
limitations therein set forth, the Securities of this series are exchangeable
for a like aggregate principal amount of Securities of this series and of like
tenor of a different authorized denomination, as requested by the Holder
surrendering the same.

     The Securities of this series shall be dated the date of their
authentication.

     All terms used in this Security which are defined in the Indenture shall
have the meanings assigned to them in the Indenture.

 
                                       6

     Unless the certificate of authentication hereon has been executed by or on
behalf of The Chase Manhattan Bank, the Trustee under the Indenture, or its
successor thereunder, by the manual signature of one of its authorized officers,
this Security shall not be entitled to any benefit under the Indenture or be
valid or obligatory for any purpose.

 
                                       7
