During the peak of Monday's rush hour in Washington, DC, around 5 p.m., a transit train collided with the rear of another train that was stopped on the tracks. Less than two hours afterward Homeland Security ruled out any possible terrorism connection.
So far there have been only six people confirmed as deceased with a rising death toll to come; rescue workers will be searching into the night for any possible survivors. At the scene of the crash, rescue workers treated 76 people for injuries.
The speed of the train was not confirmed but "the crash occurred in an area with a sizable distance between rail stations in which trains are allowed to travel at higher speed," said Metro spokeswoman Candace Smith.
