               Report of Independent Certified Public Accountants

The Pension Committee
Tax Savings Thrift Plan for Employees of
CSX Corporation and Affiliated Companies
CSX Corporation
Richmond, Virginia

We have audited the accompanying statements of net assets available for benefits
of the Tax Savings Thrift Plan for Employees of CSX Corporation and Affiliated
Companies (the Plan) as of December 31, 2001 and 2000, and the related statement
of changes in net assets available for benefits for the year ended December 31,
2001. 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, 2001 and 2000, and the changes in its net assets available for
benefits for the year ended December 31, 2001, in conformity with accounting
principles generally accepted in the United States.

NOTE 1 - DESCRIPTION OF THE PLAN

The following description of the Tax Savings Thrift Plan for Employees of CSX
Corporation and affiliated companies (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 controlled and affiliated services group defined
contribution plan covering all full-time salaried employees and certain
non-union hourly employees of CSX Corporation (CSX) and adopting affiliated
companies (collectively, the Company or Plan Sponsor). Effective January 1,
2002, CSX established the Plan as an Employee Stock Ownership Plan (ESOP)
designed to comply with Section 4975(e)(7) of the Internal Revenue Code of 1986,
as amended (Code) and be subject to the provisions of the Employee Retirement
Income Security Act of 1974 (ERISA), as amended. The designation of the Plan as
an ESOP had no material impact on the Plan provisions except as noted below.

Contributions: Each year, members may contribute, in 1% increments, up to 15% of
pre-tax or after-tax annual compensation, as defined by the Plan. Members who
are not eligible to participate in the Company's Supplementary Savings and
Incentive Award Deferral Plan may also contribute up to 25% of any incentive
compensation to the Plan. Subject to certain limitations, members may reinvest
distributions received from another qualified plan. Members may change
investment options daily. After December 31, 2001, a member may defer up to 50%
of his or her eligible compensation instead of 15%.

The Company contributes amounts equal to 50% of the first 6% of the member's
pre-tax or after-tax annual contributions, as defined by the Plan. Company
contributions are made in the form of cash deposits to the CSX Common Stock
Fund. Member incentive compensation contributions are not matched. Additional
amounts may be contributed at the option of the Company's Board of Directors.

Members who have attained age 55 may reallocate their interest in the non-member
directed CSX Common Stock Fund, in multiples of 1%, to other investment
alternatives offered under the Plan. The Plan was amended on May 1, 2002 to
allow all members diversification of the non-member directed contributions to
the CSX Stock Fund.

NOTE 1 - DESCRIPTION OF THE PLAN, Continued

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. The
benefit to which a member is entitled is the benefit that can be provided from
the 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 $50,000 in an aggregate amount of all loans from the Plan or 50%
of their vested account balance. 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 a rate commensurate with local prevailing rates as determined by the Plan
administrator. Principal and interest are paid ratably through payroll
deductions.

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
monthly installments or to initiate monthly installments. A member with an
account balance of $5,000 or less shall be paid in lump sum.

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 or partial 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, 2001 were
paid from Plan funds.

NOTE 1 - DESCRIPTION OF THE PLAN, Continued

Diversification: Investment diversification is offered to members close to
retirement so that they may have the opportunity to move part of the value of
their investment in Company stock into investments which are more diversified.
Members who are at least age 55 may elect to diversify their company match
contributions. Effective May 1, 2002, all restrictions were removed and members
may diversify their accounts immediately.

Dividends: Dividends paid on shares of Company stock held in a member's account
are reinvested in shares of Company stock. Effective January 1, 2002, a member
may elect to have dividends paid in cash to the member or his or her
beneficiaries. 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.

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

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 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.
