                         Report of Independent Auditors



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 plan
benefits, with fund information, of the Tax Savings Thrift Plan for Employees of
CSX Corporation  and Affiliated  Companies (the "Plan") as of September 30, 1998
and 1997, and the related statements of changes in net assets available for plan
benefits,  with  fund  information,  for the  fiscal  years  then  ended.  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  generally   accepted  auditing
standards.  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 plan benefits of the Plan at
September  30, 1998 and 1997,  and the changes in its net assets  available  for
plan  benefits for the fiscal years then ended,  in  conformity  with  generally
accepted accounting principles.

Our audits  were  performed  for the  purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedules of assets held
for investment purposes as of September 30, 1998 and reportable transactions for
the fiscal year then ended,  are  presented  for purposes of complying  with the
Department of Labor's Rules and Regulations  for Reporting and Disclosure  under
the Employee Retirement Income Security Act of 1974, and are not a required part
of the basic financial statements. The Fund Information in the statements of net
assets  available for plan benefits and the  statements of changes in net assets
available for plan  benefits is presented  for purposes of  additional  analysis
rather than to present the net assets  available for benefits and changes in net
assets available for benefits of each fund. The supplemental  schedules and Fund
Information have been subjected to the auditing procedures applied in our audits
of the  financial  statements  and,  in our  opinion,  are fairly  stated in all
material respects in relation to the financial statements taken as a whole.

            TAX SAVINGS THRIFT PLAN FOR EMPLOYEES OF CSX CORPORATION
                            AND AFFILIATED COMPANIES
                          NOTES TO FINANCIAL STATEMENTS
                               SEPTEMBER 30, 1998
                             (Dollars in Thousands)

NOTE 1--SIGNIFICANT ACCOUNTING POLICIES

The  accounting  records of the Tax  Savings  Thrift Plan for  Employees  of CSX
Corporation and Affiliated  Companies ("the Plan") are maintained on the accrual
basis.  All  securities  transactions  of the Plan are  recorded as of the trade
date.

Investments   in   guaranteed   investment   contracts  and   collective   trust
participation  units  included  in the Stable  Interest  Fund are fully  benefit
responsive and, accordingly,  are reported at cost plus accrued interest,  which
is contract value. Contract value approximates fair value. At September 30, 1998
and September 30, 1997, interest rates on guaranteed investment contracts of the
Stable   Interest   Fund  ranged  from  5.37%  to  8.35%  and  5.37%  to  8.35%,
respectively. The average yield on the Plan's investments in the Stable Interest
Fund for the years ended September 30, 1998 and September 30, 1997 was 6.16% and
6.09%,  respectively.  Investments in mutual funds and CSX  Corporation  ("CSX")
common  stock are  presented  at fair  value.  Fair value is based upon the last
reported  sales price on the last business day of the Plan year.  Investments in
loans to participants are carried at their outstanding principal balances, which
approximates fair value. Such loans bear interest at the prime rate in effect at
the beginning of the quarter in which each loan originated.

The preparation of financial  statements in conformity  with generally  accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets, liabilities,  income, expenses, and other
additions to or deductions from net assets. Actual results may differ from those
estimates.

Certain amounts have been reclassified from the 1997 financial  statements to be
consistent with the presentation in the 1998 financial statements.

During 1998, the Plan became a multi-employer  Plan as a result of the change in
participation of American Commercial Barge Line LLC (see Note 5).

NOTE 2--DESCRIPTION OF THE PLAN

A  complete  description  of  Plan  provisions,   including  those  relating  to
contributions,  vesting, withdrawals,  loans and distributions,  is contained in
the Summary Plan Description and the Plan document.  The prospectus  relating to
the Plan,  which  includes  the  Summary  Plan  Description,  was filed with the
Securities and Exchange Commission. Copies of these documents are available from
the CSX Benefits Department. The following summary should be read in conjunction
with the aforementioned documents.

General:  The Plan is a multi-employer  defined contribution plan subject to the
- -------
provisions of the Employee  Retirement  Income  Security Act of 1974, as amended
("ERISA").  The Plan qualifies as a "cash or deferred" arrangement under Section
401(k)  of  the  Internal  Revenue  Code  of  1986,  as  amended  ("IRC").  Plan
participation is voluntary and is limited to full-time salaried employees

affiliated companies (the "Employer").

Investment  Alternatives:  Participant  contributions  may be invested in one or
- ------------------------
more of the following investment funds: (1) the Stable Interest Fund, consisting
primarily of guaranteed  investment  contracts issued by highly-rated  insurance
companies;  (2) the  Fidelity  Equity-Income  and Growth Fund,  consisting  of a
mutual  fund  that  invests  in  various  securities  selected  primarily  for a
combination  of income and capital  growth  potential;  (3) the Vanguard S&P 500
Index  Fund,  consisting  of a mutual  fund that  invests in common and  capital

whole; (4) the Twentieth  Century Select Fund,  consisting of a mutual fund that
invests in various  securities  selected primarily for capital growth potential;
(5) the Twentieth  Century Vista Fund,  consisting of a mutual fund that invests
in the common stocks of small to medium-sized  companies  selected primarily for
capital  growth over time;  (6) the Morgan  Stanley  International  Equity Fund,
consisting  of a mutual  fund that  invests in the stocks of  companies  located
outside the United  States  selected  primarily to achieve  long-term  growth by
participating in the growth of foreign  economies;  and (7) the CSX Common Stock
Fund, consisting of investments in CSX Corporation common stock.

Amounts  allocated to any of these funds may be temporarily  retained as cash or
invested in cash  equivalents to facilitate the  investment or  reinvestment  of
Plan assets and the distribution of account balances to participants.

Participant Contributions: A participant may contribute from 1% to 15% of his or
- -------------------------
her base compensation, in 1% multiples, to the Plan (the "basic contributions").
In  addition,  the Plan  permits  participants  to  contribute  up to 20% of any
incentive compensation to the Plan. All participant contributions may be made on
a before- or  after-tax  basis  within the limits  imposed by the IRC and may be
invested in any  combination of the seven  investment  alternatives.  Investment
direction may be revised by participants daily.

Subject to certain  limitations,  a participant may also reinvest  distributions
received from another qualified plan into the Plan.

Employer Contributions: The Employer matches a participant's basic contributions
- ----------------------
in an amount equal to the lesser of 50% of those  contributions  or 3% of his or
her base compensation.  Employer matching  contributions are made in the form of
cash deposits to the CSX Stock Fund,  which are reported in the  non-participant
directed portion of the CSX Stock Fund in the accompanying financial statements.
A  participant's   incentive   compensation   contributions   are  not  matched.

NOTE 2--DESCRIPTION OF THE PLAN--Continued

Vesting,  Withdrawals,  Loans and  Distributions:  Participants  are immediately
- ------------------------------------------------
vested in all  contributions  made to their  accounts plus  investment  earnings
thereon. Withdrawals,  loans and distributions are controlled in accordance with
the provisions of the Plan.

Participant Accounts: Each participant's account is credited or charged with the
- --------------------
participant's contributions,  the employer's contributions, and an allocation of
the Plan's earnings,  losses and administrative expenses. The benefit to which a
participant  is  entitled is the  benefit  that can be provided  from his or her
account.

Plan  Termination:  Although  it has not  expressed  any  intent  to do so,  the
- -----------------
Employer 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 termination or partial  termination,  the total amount in each  participant's
account will be distributed  to the  participant or continue to be held in trust
for his or her benefit.

Administrative Expenses: The administrative expenses of the Plan are paid by CSX
- -----------------------
or from  Plan  funds  as the Plan  Administrative  Committee  from  time to time
directs. CSX paid a portion of the administrative expenses of the Plan in fiscal
years 1998 and 1997.

assets available for plan benefits.

NOTE 4--PLAN MERGER

Effective  October  1,  1996,  the RF&P  Railway  Company  Employee  Thrift  and
Investment  Plan was merged into the Plan. The merger  resulted in a transfer of
approximately $8,600 of net assets to the Plan.

NOTE 5--CHANGE IN PARTICIPATION OF AMERICAN COMMERCIAL BARGE LINE COMPANY LLC

On June 30, 1998, CSX conveyed its wholly-owned subsidiary,  American Commercial
Lines LLC (ACL), to a joint venture in which CSX holds a 32% interest. Employees
of American Commercial Barge Line Company LLC (ACBLC), a wholly owned subsidiary
of ACL,  previously  participated in the Plan. Pursuant to an Adoption Agreement
signed June 30, 1998,  ACBLC's eligible employees may continue to participate in
the Plan.

Only persons employed by ACBLC on June 29, 1998, or employees hired by the newly
formed  venture after June 30, 1998,  are eligible to  participate  in the Plan.
ACBLC  participants  may  not  invest  in the  CSX  Common  Stock  Fund  and may
reallocate  amounts  previously  invested in the CSX Common  Stock Fund to other
investment alternatives.

NOTE 6--INCOME TAX STATUS

The Internal  Revenue  Service ruled on March 15, 1996,  that the Plan qualifies
under Sections 401(a) of the Internal Revenue Code ("IRC") and,  therefore,  the
related  trust  is not  subject  to tax  under  present  income  tax  law.  Once
qualified,  the  Plan is  required  to  operate  in  conformity  with the IRC to
maintain its qualification. The CSX Administrative Committee is not aware of any
course of action or series of events  that have  occurred  that might  adversely
affect the Plan's  qualified  status.  No  provision  for income  taxes has been
included in the Plan's financial statements.

The Plan  Administrator is not aware of any course of action or series of events
that have occurred that might adversely  affect the Plan's  continued  qualified
status.

NOTE 7--RELATED PARTY TRANSACTIONS

CSX and its subsidiaries provide the Plan with certain management and accounting
services.  During  fiscal  years  1998 and  1997,  the Plan  reimbursed  CSX and
subsidiaries approximately $149 and $121, respectively, for those services which
are  considered  reasonable  and customary  expenses of the Plan.  During fiscal
years  1998 and  1997,  the  Plan  received  $5,695  and  $4,788,  respectively,
representing cash dividends from CSX common stock.

The trustee,  The Northern Trust Company,  routinely  invests Plan assets in the
Collective  Short-Term  Investment  Fund of The Northern Trust Company.  For the
fiscal year ended  September  30,  1998,  transactions  involving  this  account
included 360  purchases  with a total cost of $297,215 and 352 sales with a fair
value of $297,147.  For the fiscal year ended  September 30, 1997,  transactions
involving this account  included 213 purchases with a total cost of $211,919 and
218 sales with a fair value of $215,604.

NOTE 8--CONRAIL TRANSACTION

Due to the  joint  acquisition  of  Conrail  Inc.  by CSX and  Norfolk  Southern
Corporation, approximately 790 former Conrail employees will become eligible for
the Plan on or about June 1, 1999.
