DC Metro chief: First train stopped, second hit it

WASHINGTON — The general manager of the Washington Metro says the two-train collision occurred when one train stopped at a platform near the Fort Totten station, and a second train hit it from behind.

John Catoe told reporters Monday that for reasons we do not know the second train plowed into the back of that train. He spoke at a news conference near the scene about two hours after the crash.

The National Transportation Safety Board is currently the lead investigating agency on the crash.

At least four people died in the crash, including the operator of the trailing train, which occurred shortly after 5 p.m. Nearly 70 were injured, including two seriously.
