Amtrak Engineer Made No Report of Object Hitting Windshield Before Crash

U.S. federal investigators have found no record that the engineer of the Amtrak commuter train that crashed in Philadelphia last week reported an object hit his locomotive in the minutes before it derailed, a U.S. official said on Sunday. The comment by Sumwalt comes as investigators are looking to explain what caused a circular pattern of damage found on the locomotive's windshield after the accident. The engineer, Brandon Bostian, 32, who suffered a concussion in the crash, has told investigators he has no memory of what occurred after the train pulled out of the North Philadelphia station, just before the crash. The train, which was barreling north at double the 50-mile-per-hour speed limit when it entered a sharp curve and derailed, was traveling from Washington to New York with 243 people on board. Before Friday's disclosure about possible projectiles, the probe was focusing on why the train accelerated to 106 mph from 70 in the minute before it derailed. The NTSB has not ruled out mechanical issues, human error or a deliberate act by the engineer, among other factors.
