WASHINGTON (Reuters) - Two Washington D.C. subway trains collided during the afternoon rush hour on Monday, killing at least two people, officials said.
The NBC local affiliate said up to 55 people were injured.
The Washington Metropolitan Area Transit Authority, which runs the "metro" subway system for the U.S. capital region, said a six-car Red Line train headed out of town derailed and collided with another train at 5 p.m. EDT/2100 GMT on Monday.
NBC showed the front of one train lying on top of the front of the other train in open-air track in the north of the city. It said emergency workers were trying to free some of those trapped on the trains.
Fox television's local news affiliate showed passengers being escorted from a Metro train outside the Fort Totten station. The station said power to the station was shut off.
A reporter with the station said he saw what appeared to be a body covered with a sheet, and several injured passengers including one wearing a neck brace.
Witnesses said fire department vehicles and ambulances were also at the scene, while television pictures showed rescue officials taking injured people off the tracks.
