Released: Jul 31, 2008

Jacksonville, FL - July 31, 2008 - CSX Corporation (NYSE: CSX) today announced that IVS Associates, Inc., the inspector of election for CSX's 2008 annual meeting of shareholders, issued its final report, showing that four of the TCI Group's nominees received a larger number of votes than four of CSX's nominees.

CSX will continue to work diligently in an effort to resolve all remaining issues with respect to the meeting vote. The Company hopes that all such issues will be resolved before September 24, 2008, the date the Company will reconvene the annual meeting. CSX said the final outcome of the director election remains uncertain for two reasons, one involving a judicial appeal and the other involving questions in the vote count.

Two of the Board seats involving TCI Group nominees, Timothy O'Toole and Christopher Hohn, will be determined by an appeal before the Second Circuit Court of Appeals. In that case, CSX has asked the Court to prevent the TCI Group from voting 6.4 percent of the outstanding shares of CSX. A Federal District Court determined that those shares were acquired by the TCI Group while it was engaged in illegal conduct with respect to CSX securities. If the Court decides in favor of the CSX position, Mssrs. O'Toole and Hohn will not have the votes needed to be elected to the Board. The Second Circuit has scheduled the case for expedited hearing on August 25, 2008. The case goes to the integrity of the election, and the Company is hopeful that it will be completed before the September 24, 2008 meeting and before the next regularly scheduled Board meeting in October.

One of those two seats, involving Mr. Hohn and CSX nominee, Dr. Frank Royal, is also the subject of controversy surrounding the tabulation of votes from other shareholders. Despite serious challenges, the inspector determined that Mr. Hohn received 790,412 more votes than Dr. Royal, a margin of less than three tenths of one percent of the votes cast.

Among other things, the Company challenged the inspectors' failure to count more than half a million votes cast under three union-sponsored 401k plans, notwithstanding the clear intention of the plan trustee to cast those votes for Dr. Royal. If these and other challenged votes were counted as the Company believes they should have been, Dr. Royal would have received more votes than Mr. Hohn, regardless of the outcome of the pending litigation in the Second Circuit appeal. The Company is considering its options with respect to these challenged votes.

The IVS preliminary and final reports indicated that Gilbert H. Lamphere and Alexandre Behring would be elected as directors of the Company. The Board promptly offered seats to Messrs. Lamphere and Behring, who joined the Board effective July 28, 2008.
