A New York City commuter train rounding a riverside curve derailed Sunday, killing four people and injuring more than 60 in a crash that threw some riders from toppling cars and swiftly raised questions about whether excessive speed, mechanical problems or human error could have played a role, AP reported. Some of the roughly 150 passengers on the early morning Metro-North train from the town of Poughkeepsie to Manhattan were jolted from sleep around 7:20 a.m. to screams and the frightening sensation of their compartment rolling over on a bend in the New York City borough of the Bronx where the Hudson and Harlem rivers meet. When the motion stopped, all seven cars and the locomotive had lurched off the rails, and the lead car was only inches from the water. It was the latest accident in a troubled year for the second-biggest U.S. commuter railroad, which had never experienced a passenger death in an accident in its 31-year history.
