Two subway trains collided Monday in the US capital-Washington, leaving four people dead and scores injured, Mayor Adrian Fenty said. The accident occurred around 5 pm (2100 GMT) near Washington's border with the state of Maryland, on a section of track above ground. One train had apparently stopped between stations before being struck from behind by a second train. Local news footage showed one heavily damaged carriage pushed up on top of another. The force of the collision tore the floor out of the moving train as it vaulted onto the stopped carriage. The driver of the moving train was reported among the dead, according to a report of DPA.
