Unlike air travelers, railroad passengers don't have to go through electronic scanners or have their luggage searched before boarding.
U.S. officials said information seized from al-Qaida leader Osama bin Laden's compound last week included a plan to try to disrupt rail transportation on the 10th anniversary of the Sept. 11, 2001, terror attacks in the United States, the Christian Science Monitor reported Monday.
Bin Laden was killed May 2 in a raid by U.S. forces in Pakistan.
"We're going to look at all these security matters," Transportation Secretary Ray LaHood said during a news conference in New York. "We're going to look at everything and then we'll make a judgment with our friends in Congress and decide what direction we should go."
As part of its budget-cutting work for fiscal year 2011, Congress lopped $50 million from a $300 million grant program meant to enhance rail security.
Given the information uncovered among bin Laden's documents, Sen. Charles Schumer, D-N.Y., suggested lawmakers may want to revisit the cut.
"I think we ought to re-examine that and try to restore that money and maybe make it go a little further," said Schumer, who joined LaHood at the news conference, which was called to announce $2 billion in high-speed rail awards.
Schumer said he though Amtrak could begin to instituting a no-ride list since the carrier knows the names of the people traveling on each train.
"It does not seem that difficult to do," Schumer said. "They are looking at it right now, looking at the feasibility."
