               Report of Independent Certified Public Accountants

The Finance Committee of the Board of Directors
CSX Corporation Capital Builder Plan
CSX Corporation
Jacksonville, Florida

We have audited the accompanying statements of net assets available for benefits
of the CSX Corporation Capital Builder Plan as of December 31, 2002 and 2001,
and the related statement of changes in net assets available for benefits for
the year ended December 31, 2002. These financial statements are the
responsibility of the Plan's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States. Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the financial statements are free
of material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for benefits of the Plan as of
December 31, 2002 and 2001, and the changes in its net assets available for
benefits for the year ended December 31, 2002, in conformity with accounting
principles generally accepted in the United States.

NOTE 1 - DESCRIPTION OF THE PLAN

The following description of the CSX Corporation Capital Builder Plan (the Plan)
provides only general information. Members should refer to the Summary Plan
Description and the Plan document for a more complete description of the Plan's
provisions.

General: The Plan is a defined contribution plan covering certain union
employees of CSX Corporation (CSX) and affiliated companies (collectively, the
Company or Plan Sponsor). The Plan is an Employee Stock Ownership Plan (ESOP)
designed to comply with Section 4975(e)(7) of the Internal Revenue Code of 1986,
as amended and is subject to the provisions of the Employee Retirement Income
Security Act of 1974 (ERISA), as amended.

Contributions: Effective January 1, 2002, the Plan was amended to allow a member
to contribute from 1% up to 50%, (in 1% multiples) of eligible compensation, as
defined by the Plan, on a pre-tax or after-tax basis. Prior to January 1, 2002,
members could contribute a maximum of 15% of eligible compensation. Certain
eligible members may also contribute other compensatory awards to the Plan.
Subject to certain limitations, members may reinvest distributions from another
qualified plan or Individual Retirement Account. Members may change percent of
contribution and investment options daily.

The Company contributes the value of a specified number of shares of CSX common
stock on an annual basis to certain member accounts of the eligible groups, as
defined by the Plan (ESOP Allocation). In 2002, Company contributions were
funded from the CSX Corporation rabbi trust account which holds CSX common stock
and cash. Shares to fund the contributions may be purchased throughout the year
and held by CSX Corporation in a rabbi trust until they are contributed to the
Plan and credited to the members' accounts.

The Plan also provides for a Company matching contribution of stock or cash to
certain eligible members. The amount and timing of the Company contributions
varies according to applicable collective bargaining agreements. All Company
contributions are invested in CSX common stock, except for certain contributions
that can be directed by the members of certain eligible groups as defined by the
Plan.

NOTE 1 - DESCRIPTION OF THE PLAN (Continued)

Diversification: The Plan was amended effective May 1, 2002 to allow all members
to immediately diversify the nonmember-directed contributions to the CSX Stock
Fund to other investment options offered under the Plan. Prior to May 1, 2002,
the Plan was amended effective January 1, 2002 to change the age requirement for
a member to diversify nonmember-directed contributions from age 55 to age 50.

Member Accounts: Each member's account is credited with the member's
contributions and allocations of (a) the Company's contributions and (b) Plan
earnings, and is charged with an allocation of administrative expenses.
Allocations are based on member earnings or account balances, as defined. The
benefit to which a member is entitled is the benefit that can be provided from
the member's account.

Vesting:  Members are 100% vested in their accounts.

Loans: Members may borrow from their account in amounts equal to no more than
the lesser of $50 in an aggregate amount of all loans from the Plan or 50%
of their vested account balance. Members may not borrow from an ESOP account or
the Company match account even though those accounts are used in the calculation
to determine the amount available for the loan. Loan terms range from one to
five years unless the loan is to be used in conjunction with the purchase of a
primary residence. The loans are secured by the balance in the member's account
and bear interest at the prime rate in effect at CitiBank at the beginning of
the quarter in which the loan originated. Principal and interest are paid
ratably through payroll deductions.

Dividends: Dividends paid on shares of Company stock held in a member's account
are reinvested in shares of Company stock. A member or spousal beneficiary may
elect to have dividends paid to them in cash. Any change in an election will
apply only to ex-dividend dates occurring after the date such election is
received. A member who does not make a timely election will have the dividends
paid to their account and reinvested in shares of Company stock.

Payment of Benefits: Upon termination of service, a member may receive a
lump-sum amount equal to the vested value of his or her account, or upon
disability or retirement, elect to receive monthly installments over a 240-month
period. Surviving spouses of retired or disabled members may elect to continue
or initiate monthly installments. A member with an account balance of $5 or
less shall be paid in lump sum.

NOTE 1 - DESCRIPTION OF THE PLAN (Continued)

Plan Termination: Although it has not expressed any intent to do so, the Company
has the right under the Plan to discontinue its contributions at any time and to
terminate the Plan subject to the provisions of ERISA. In the event of Plan
termination, members will remain 100% vested in their accounts.

Administrative Expenses: The administrative expenses of the Plan are paid by the
Company or from Plan funds as the Plan Sponsor directs. All of the
administrative expenses of the Plan during the year ended December 31, 2002 were
paid from Plan funds.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation: The financial statements have been prepared under the
accrual method of accounting in accordance with accounting principles generally
accepted in the United States.

Use of Estimates: The preparation of financial statements in conformity with
accounting principles generally accepted in the United States requires
management to make estimates that affect the amounts reported in the financial
statements and accompanying notes. Actual results could differ from those
estimates.

NOTE 3 - INVESTMENT IN MASTER TRUST

All investments of the Master Trust are held by The Northern Trust Company, the
Master Trust's trustee.

At December 31, 2002 and 2001, the Plan's interest in the net assets of the
Master Trust was approximately 31%.

Investments in CSX Common Stock (stated at fair value) are valued at the last
reported sales price on the last business day of the year. Investments in mutual
funds are measured by quoted market prices and are reported at aggregate fair
value at year-end. Synthetic guaranteed investment contracts (defined on page
10) are reported at fair value, which in the case of such contracts approximates
contract value. Member loans are valued at their outstanding balances, which
approximates fair value.

Purchases and sales of securities are recorded on a trade-date basis. Interest
income is recorded on the accrual basis. Dividends are recorded on the
ex-dividend date.

Note 4 - NONMEMBER-DIRECTED INVESTMENTS

members to reallocate their nonmember-directed contributions to the CSX Stock
Fund. Therefore, as of May 1, 2002 there were no nonmember-directed investments.

in net assets relating to the nonmember-directed investments is as follows:

NOTE 6 - INCOME TAX STATUS

The Plan has received a determination letter from the Internal Revenue Service
dated March 12, 2002, stating that the Plan is qualified under Section 401(a) of
the Internal Revenue Code and, therefore, the related trust is exempt from
taxation. Subsequent to this issuance of the determination letter, the Plan
was amended.  Once qualified, the Plan is required to operate in conformity
with the Code to maintain its qualification. The Plan Sponsor believes the Plan
is being operated in compliance with the applicable requirements of the Code
and, therefore, believes that the Plan, as amended,  is qualified and the
related trust is tax exempt.
