U.S. Plans Law Enforcement 'Surge' On Trains

U.S. authorities plan a law enforcement surge this week along Amtrak routes, an exercise called RailSafe, and the heads of the country's biggest mass transit systems were briefed today on the possible terror threat, all part of what is being called an abundance of caution.

Amtrak is holding a high-security exercise Friday in which uniformed officers will be a visible presence on national transit routes. RailSafe will include all the local police agencies along the Amtrak routes involved in the exercise.
