Amtrak train thought to be going twice as fast as it should have been
How do all seven cars and the engine of an Amtrak train jump the rails, sending passengers, luggage, laptops and more flying?
One possibility loomed over all others Wednesday: speed.
Authorities haven’t said what caused the derailment of Amtrak Northeast Regional Train 188 in Philadelphia on Tuesday night. But the National Transportation Safety Board said that preliminary data show the train’s speed exceeded 100 mph before the derailment. That would be more than twice the 50 mph speed limit for the curve it was in.
Some 238 passengers and five crew members were on the train when it crashed around 9:30 p.m. Tuesday. Authorities said that at least seven people were killed.
