Faster than a speeding bullet train (you know,in Japan) Amtrak, the nation's leading passenger rail line (okay, it's the nation's only passenger rail line) issued notification that they are clamping down on possible terrorist attacks on their trains. Armed guards with bomb-sniffing dogs will patrol platforms and trains in Washington, DC's Union Station, performing random searches on passengers and their baggage.
Remember, it was little more than six years ago (that's only 72 months!) that terrorists used jumbo jets to bring down the World trade Center.
Amtrak officials said the rapid response was necessary to ensure they're dozens of passengers that their security and safety were of utmost importance.
