NTSB: Train was speeding up for 1 minute before it derailed
PHILADELPHIA (AP) – Federal investigators say it’s unclear why the Amtrak train that derailed in Philadelphia sped up from 70 mph to just over 100 mph in the final full minute before it left the tracks at a sharp curve.
A member of the National Transportation Safety Board says the speed was determined by a camera mounted on the front of the train.
It went dark after the train crashed, killing eight people.
The engineer has agreed to speak with investigators.
