'' WALTHAM, Mass.—Firefighters in Waltham say they will practice responding to a train crash on Sunday in a rescue drill that will cause a traffic detour.
The training drill will happen at the city's Beaver Street railroad crossing near Waverly Oaks Road starting at 7:30 a.m. Sunday.
Authorities say a portion of Beaver Street will be closed for about five hours.
The exercise will simulate a crash involving a car, a tractor-trailer and a MBTA commuter rail train.''
