CSX REPORTS STRONG FIRST QUARTER 2005 EARNINGS
Company Produces Record Surface Transportation Operating Income

     JACKSONVILLE, Fla., April 28, 2005 – CSX Corporation (NYSE: CSX) today reported its financial results for the first quarter of 2005.

•   Net earnings were $579 million, or $2.56 per share, including a net after-tax gain of $425 million, or $1.88 per share, resulting from the sale of the Company’s International Terminals business.

•   Earnings per share from continuing operations were 68 cents in 2005 versus 13 cents in the prior year’s quarter, which was reduced by a 14-cent management restructuring charge at the Company’s Surface Transportation units in 2004.

•   Surface Transportation operating income was a record $351 million versus $151 million a year ago, which was reduced by a $53 million management restructuring charge in 2004.

     CSX’s core Surface Transportation businesses produced record operating income, driven by a 10 percent increase in revenue and better cost discipline. On a comparable basis, adjusting for the 2004 management restructuring charge, Surface Transportation operating income for 2005 increased $147 million, or 72 percent, year over year. CSX’s operating ratio for the quarter was 83.3 percent, an improvement of more than 6 points versus the first quarter of 2004.

     “We are very pleased with the 72 percent year-over-year increase in operating income that the employees of CSX produced in the first quarter,” said Michael Ward, CSX Corporation chairman, president and chief executive officer. “CSX continued on its path of consistent, continuous improvement producing year-over-year growth in core earnings for the fifth consecutive quarter.”

     Surface Transportation revenue for the quarter was $2.1 billion versus $1.9 billion in the same quarter last year. Revenue gains in the quarter were led by strength in the Company’s coal and merchandise markets, which produced 20 percent and 8 percent year-over-year revenue gains, respectively.

     Ward added, “A strong pricing environment resulting from high demand contributed significantly to the Company’s year-over-year revenue growth with CSX’s value pricing and yield management initiatives, along with the fuel surcharge program, driving the top line improvements.

     “The Company remains focused on continuing to drive improvements in its operational and safety performance, sustaining its top line performance by pricing our service to market levels, and improving our bottom line performance through better cost discipline,” said Ward.

     Also in the first quarter of 2005, CSX sold its International Terminals business for cash consideration of $1.142 billion, subject to final working capital and long-term debt adjustments that have not yet been determined. CSX recognized an after-tax net gain of $425 million as a result of the sale, including a loss on operations for the quarter.

     CSX’s detailed financial information is contained in the Company’s Quarterly Flash document, which will be posted on the Company’s website, www.csx.com, and filed on Form 8-K with the Securities and Exchange Commission today.

SURFACE TRANSPORTATION OPERATING RESULTS

REVENUE

Merchandise
Merchandise revenue was up 8% on relatively flat volume during the first quarter of 2005. All markets showed year-over-year improvement in revenue per car due to continued price increases and the Company’s fuel surcharge program.

•   Phosphates and Fertilizers – Strength in revenue yield offset volume weakness and mix changes, as overall revenue grew 1%. Domestic phosphate demand was soft, causing interior phosphate revenue to fall by 24% while shorter haul export phosphate revenue grew 15%.

•   Metals – Despite a 1% decline in volume, metals revenue grew 16% due to market pricing and favorable mix changes. Strong demand continues to sustain high levels of steel production, but the sources of the strength are beginning to shift from automotive to construction. Imports have also been strong.

•   Forest Products – Paper markets produced significantly higher revenue despite lower volume in several lines of business. Volume strength in lumber and panel markets was offset by declines in several paper markets. U.S. newsprint demand dropped over 4% during the first two months of the year, while imports continue to affect domestic paper production.

•   Food and Consumer – Volume was favorable by 7%, led by gains in building products and alcoholic beverages. Even stronger revenue gains of 19% were driven by continued yield management success and gains in transportation equipment.

•   Agricultural Products – Volume was flat due to weakness in domestic beans and processed products markets. However, revenue was favorable on strength in export and ethanol shipments, as well as revenue per car increases in feed ingredients, sweeteners and flour.

•   Chemicals – Revenue grew 7% on relatively flat volume. Gains were strongest in textile chemicals, bleach/paper chemicals, and petroleum products. The plastics market experienced volatility during the quarter as buyers reduced existing inventories; but revenue still grew 4%. Sand shipments were down due to car shortages and losses of marginal traffic.

•   Emerging Markets – Volume was favorable overall as strength in most lines of business offset weakness in military shipments. Volume strength was primarily driven by growth in northern aggregates of 32% and salt of 23%. An unfavorable military mix impact drove an overall decline in revenue per car.

Automotive
Revenue increased 3% on flat volume as a result of yield improvements. North American light vehicle production decreased 179,285 units, or roughly 4%, year over year. Inventory levels remain high, at 69 days for most manufacturers and 79 days for the Big 3. Manufacturers are using production downtime and incentives to address excess inventory.

Coal, Coke and Iron Ore
Overall coal, coke and iron ore revenues were favorable 20% year over year. Volume was favorable 9% or 38,000 carloads. Growth was driven by volume gains in export, industrial, coke, and utility north markets. Revenue per car growth was the result of market price increases and the Company’s fuel surcharge program offsetting slightly unfavorable mix. All lines of business reflect favorable year-over-year revenue-per-car gains.

Intermodal

•   Domestic – Volume comparisons were negatively impacted by the Network Simplification Initiative implemented in July 2004 which eliminated 26 weekly train starts, severe west coast weather, and service issues. Offsetting the volume weakness, market rate increases significantly improved revenue per unit.

•   International – Revenue gains were largely driven by increases in traffic on the core network. Decreases in off-core and transcontinental traffic were impacted by marketing changes and the west coast embargo which was caused by severe weather.

•   Other – Overall revenue strength was driven by favorable changes in incentive refund programs, fuel surcharge, and an increase in per diem and supplemental charges related to asset utilization.

EXPENSE

Labor and Fringe expenses increased $17 million in the first quarter of 2005 versus the prior year quarter. The effects of inflation continue to drive labor and fringe expense increases, along with increases in incentive compensation. These costs were partially offset by benefits realized from reduced staffing levels.

Materials, Supplies and Other expenses increased $46 million during the first quarter of 2005 as compared to the prior year quarter. The increase is associated with volume and inflation related expenses as well as an increase in expenses related to the resolution of certain legal matters and higher reserve requirements for uncollectible accounts.

Depreciation increased $43 million for the first quarter of 2005 due to an increased depreciation base, mainly attributable to the Conrail spin-off transaction, as assets previously leased from Conrail are now owned directly by CSX.

Fuel increased $25 million for the quarter versus the prior year due to higher fuel prices, net of hedging benefits.

Inland Transportation decreased $18 million primarily due to decreased Intermodal volume on the western network.

Conrail Rents, Fees and Services decreased $67 million for the quarter primarily due to the Conrail spin-off transaction completed in the third quarter of 2004. This transaction decreased rents paid to Conrail, as assets previously leased from Conrail are now owned directly by CSX.

Restructuring Charge of $53 million represents the 2004 charge for separation expenses related to the management restructuring announced in November 2003 at Surface Transportation.
