Air Marshals May Also Work on Trains

The Washington Post reports that "teams will take positions in public areas along Amtrak's Northeast Corridor and Los Angeles rail lines; ferries in Washington state; and mass transit systems in Atlanta, Philadelphia and Baltimore."

This doesn't bother me a whole lot provided it doesn't slow down train boardings too much.
