Sen. Schumer calls for "Do Not Ride" list for trains?

Sometimes I am truly amazed by Sen. Schumer. A "do not fly" list for planes makes a lot of sense in theory because the only way you can knock down a plane is to either be on board, crash another plane into it (something that is probably very difficult given air traffic control), or fire a missile at it (something that isn't readily available). A "do not ride" list for trains is pretty silly because you don't have to be on a train to attack it. There are thousands of miles of track and there is no way that you are going to be able to defend all of it. Given the error rate on the "do no fly" list, a "do not ride" list would be all errors and costs and provide little benefit.

Sen. Charles Schumer is calling for better rail security now that the raid on Osama bin Laden’s compound has turned up plans to attack trains in the U.S.
“Anyone, even a member of al-Qaida could purchase a train ticket and board an Amtrak train without so much as a question asked,” Schumer said. “So that’s why I’m calling for the creation of an Amtrak no ride list. That would take the secure flight program and apply it to Amtrak trains.”
Schumer said Sunday that he will push for the creation of a “do not ride” list for Amtrak. The list would be similar to the no-fly list that keeps those suspected of terrorism from flying into or out of the United States. . . .
