CSX Announces Internet Availability of Proxy Materials

Effort Will Save 25 Million Pages of Printing

JACKSONVILLE, Fla., March 24 /PRNewswire-FirstCall/ -- CSX Corporation (NYSE:
CSX) today announced that the proxy materials for its 2009 Annual Shareholders
Meeting, including its proxy statement and 2008 Annual Report, are now
available to shareholders via the Internet under the Securities and Exchange
Commission's Notice and Access rules.

Last year CSX distributed nearly 190,000 annual reports. This year, the
company is demonstrating its commitment to the environment and cost control by
mailing copies by request only and posting the same information online. The
company expects to reduce printing by more than 25 million pages.

Pursuant to the SEC's Notice and Access rules, CSX is delivering a "Notice
Regarding the Availability of Proxy Materials" (the "Notice") to its
shareholders of record instead of paper copies of its proxy materials. The
Notice contains instructions regarding how to access and view the proxy
materials over the Internet and how to vote electronically over the Internet
and in other ways. Shareholders may obtain paper copies of the proxy materials
by following the instructions provided on the Notice. In addition, this
process provides shareholders the opportunity to join with CSX in continuing
to enhance its role in protecting the environment.

CSX's 2009 Annual Shareholders Meeting will be held on Wednesday, May 6, 2009
at 10:00 a.m., (EDT) at the Baltimore Marriott Inner Harbor at Camden Yards,
110 South Eutaw Street, Baltimore, MD 21201-1608.

In his annual letter to shareholders, Michael Ward, chairman, president and
CEO noted that the change in distribution of CSX's 2008 annual report
"represents a small but important example of our environmental leadership."
CSX was the first railroad to join the EPA's Climate Leaders Program and is
committed to developing long-term, comprehensive climate change strategies.
