Federal investigators visited a Metro-North train crash site Wednesday where six people were killed and 15 were injured.
A train on the Harlem Line crashed into an SUV Tuesday evening in the Westchester County town of Valhalla, New York. It's considered the worst accident in the history of the rail line.
New York Senator Charles Schumer told reporters Wednesday that the train was traveling at about 58 mph, within the speed limit for the area, which ranges between 60 and 70 mph. Federal investigators gathered other information about whether the train's brakes were applied, and whether its horn sounded as it approached a crossing.
