Amtrak passengers will see more police at stations and on trains from New Hampshire to Virginia as part of a drill to test counterterrorism and incident response capabilities.
Amtrak says Thursday's drill is not a response to any particular threat.
The company says passengers can expect heightened patrols, increased security on trains, explosive-sniffing dogs and random bag inspections.
The drill was scheduled for the morning and afternoon rush hours.
