Update:  A National Transportation Safety Board official says the engineer of an Amtrak train that derailed in Philadelphia applied the emergency brakes just before the crash. National Transportation Safety Board member Robert Sumwalt said that the train was traveling at 106 mph when the engineer hit the brakes.  The derailment took place as the train entered a curve where the speed limit is 50 mph. The speed limit on the track just prior to the curve is 70 mph. (Associated Press)

Original Story:  Philadelphia police officials say the engineer of the Amtrak train that crashed, killing seven people and injuring more than 200, declined to provide a statement to investigators.

They say the engineer also had an attorney when he left a meeting today with investigators at a police precinct. The engineer has not yet been identified.

Investigators are trying to determine why the train slipped off the tracks while rounding a sharp curve Tuesday night northeast of Philadelphia's city center.

Authorities say the locomotive's data recorder has been recovered and that it should yield critical information, including the speed of the train.

The speed limit just before the curve was 70 mph and on the curve it was 50 mph.

The Federal Railroad Administration says Amtrak inspected the tracks just hours before the derailment and found no defects.
