CBS: "Al Qaeda's Goal: Cripple Amtrak's Northeast Corridor"

The Mumbai terror attacks included hitting the main train station in the city, the Chhatrapati Shivaji Railway Station, where 10 people were shot and killed and many others wounded. Any terror attack anywhere in the world would most certainly include main transportation hubs. Philly and NY are the third and first busiest train stations in the US respectively. They are targets, no question.

The CBS story from November 26th states:
"Uniformed officers, including this NYPD Counter Terrorism Squad members and Amtrak cops with M-16s, flooded Penn Station Wednesday after the FBI said it had received a 'plausible but unsubstantiated' report that Al Qaeda operatives discussed a plan two months ago to bomb New York City's mass transit system"

This is scary but Philly and NY have the police resources with the equipment and experience to respond and prevent terror attacks before they arise. I take the NYC subway everyday and I generally feel OK and safe doing so. I'd feel the same on Amtrak as well if I was still a regular commuter.  "See Something, Say Something":  this is all over the place in the NYC subway system; it's applicable for Amtrak commuters as well.
