Amtrak's board of directors has fired the president of the passenger railroad, David Gunn.
Gunn has repeatedly clashed with the Bush administration, especially over federal subsidies for the program.
Amtrak has never made money in its 34-year history.
Board Chairman David Laney says Amtrak requires a leader who will aggressively tackle the company's financial, management and operational challenges.
Gunn has been on the job since 2002, after heading transit systems in New York City, Washington and Toronto.
