Amtrak's board called a meeting for Wednesday and plans to fire President David Gunn, according to Sen. Charles Schumer, D-N.Y.

Gunn has clashed with the Bush administration since assuming the post in 2002. He has said Amtrak can't survive without federal subsidies while the administration has pushed to eliminate them.

The board scheduled a meeting for 2 p.m. and plans to fire Gunn, Schumer told The Associated Press, citing "a very high and reliable source."

Schumer called Gunn's removal "a crushing blow to Amtrak's hopes for success and reform," and praised him as "a brilliant manager."

Gunn, who came to Amtrak after having headed transit systems in New York City, Washington and Toronto, could not be reached to comment. A call to Amtrak's chairman David Laney was not immediately returned.

In September, Amtrak's board approved a resolution authorizing splitting off the Northeast Corridor, which accounts for the largest share of the railroad's ridership. That region could be operated by a federal-state consortium.

The Bush administration favors the idea, but critics say it will destroy Amtrak.

Amtrak has never made money in its 34-year history and an operating loss of more than $550 million was expected for the fiscal year that ended Sept. 30. The railroad has a debt of more than $3.5 billion.

The White House has called for an end to subsidies for Amtrak, but the House has approved an appropriation of nearly $1.2 billion for this budget year.

In recent months, Amtrak has been besieged by problems up and down the line, from equipment breakdowns to big-ticket budget woes.

Earlier this year, Amtrak suspended all high-speed Acela service between Washington, New York City, and Boston, due to cracks discovered in the brakes.

A report issued last week by the Government Accountability Office, the auditing arm of Congress, said the company needs to improve the way it monitors performance and oversees its finances in order to reach firm financial footing.

"The company is likely to need outside help in developing a comprehensive approach to address internal control weaknesses and improve the financial information for management and external stakeholders," the report found.

The GAO recommended that the transportation secretary direct the Federal Railroad administrator to: require Amtrak to submit a plan laying out specifically how it will improve its financial operations; provide Amtrak with direction on how to do so; and monitor the railroad's performance and report to Congress on Amtrak's progress.

Transportation Secretary Norman Y. Mineta later called the report "unusual, if not unprecedented, in the scope of its review and the severity of its indictment." He urged the board to "stop and take a fresh look on how to proceed in the face of this nonpartisan, objective report of systemic failure."
