Cranes salvage the last car from from a train derailment in the Bronx section of New York, Monday, Dec. 2, 2013. Federal authorities began righting the cars Monday morning as they started an exhaustive investigation into what caused a Metro-North commuter train rounding a riverside curve to derail, killing four people and injuring more than 60 others. A second "event recorder" retrieved from the train may provide information on the speed of the train, how the brakes were applied, and the throttle setting, a member of the National Transportation Safety Board said Monday.

YONKERS, N.Y. (AP) - The National Transportation Safety Board says a train that derailed in New York City was traveling 82 mph as it approached a 30 mph zone.
The Metro-North Railroad commuter train jumped the tracks Sunday morning along a sharp curve where the speed limit drops from 70 mph to 30 mph. Four passengers died.
National Transportation Safety Board investigators on Monday mined the train's data recorders, shedding light on such things as the train's speed and the use of its brakes. NTSB member Earl Weener says he's unaware of any problem with the train's brakes.
The investigators have also sought to question the engineer and conductor for clues. The rail employees union says engineer William Rockefeller was injured in the wreck and is cooperating with investigators.
