A New York City passenger train derailed, killing four people, injuring more than 60 and 11 critically wounded.
Four people killed were identified as New York residents as federal authorities say they will examine data recorders to try to determine whether excessive speed, mechanical problems or human error could have played a role in the accident.
There were roughly 150 passengers on the early morning Metro-North train from the town of Poughkeepsie to Manhattan.
Some were jolted from sleep around 7.20am 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 carriages and the steam engine had swayed off the rails, and the lead carriage was only inches from the water.
It was the latest accident in a troubled year for the second-biggest US commuter railroad, which had never experienced a passenger death in an accident in its 31-year history.
May the soul of the departed rest in perfect peace!
