Released: May 2, 2008

Jacksonville, FL - May 5, 2008 - CSX Corporation (NYSE: CSX) today announced that it has filed an investor presentation with the Securities and Exchange Commission ("SEC") in connection with the company's 2008 annual meeting of shareholders, which is scheduled for Wednesday, June 25, 2008.

"CSX's Board of Directors has driven extraordinary shareholder returns, financial and operational performance, and excellence in corporate governance and offers a compelling future outlook," said Michael J. Ward, CSX chairman, president and chief executive officer. "We look forward to meeting with CSX investors to discuss our track-record of success and concrete plans to continue to create value for all shareholders. We believe that the block of TCI group nominees, if elected, may seek to implement an agenda that would damage CSX's future success and returns to shareholders."

The CSX Board of Directors recommends that shareholders re-elect its experienced and highly qualified directors and support the Board's efforts to create additional value by promptly voting the WHITE proxy card by telephone, Internet or mail. CSX also strongly urges shareholders to disregard any blue proxy card sent by The Children's Investment Fund ("TCI") or other members of TCI's group, including 3G Capital Partners.

The investor presentation is available in the "Investor Presentation" section of the company's annual meeting website at 2008annualmeeting.csx.com or at the SEC's website at www.sec.gov. CSX shareholders who have any questions or need assistance voting their WHITE proxy card should contact Innisfree M&A Incorporated, which is assisting the Company in this matter, toll-free at 877-750-9497.
