DUPONT, Wash. — An Amtrak train making the first-ever run along a faster new route hurtled off an overpass south of Seattle on Monday and spilled some of its cars onto the highway below, killing at least three people, injuring dozens and crushing two vehicles, authorities said.
Attention quickly turned to the train's speed. Federal investigators say the train was traveling at 80 mph (129 kph) in a 30 mph (48 kph) zone. Bella Dinh-Zarr, an NTSB board member, said at a Monday night news conference that information from the event data recorder in the rear locomotive provided information about the train's speed.
Dinh-Zarr said it's not yet known what caused the train to derail and that "it's too early to tell" why it was going so fast.
She said federal investigators will likely be on scene for a week or more.
There were 80 passengers and five on-duty crew on board when the train derailed and pulled 13 cars off the tracks. Authorities said there were three confirmed deaths. More than 70 people were taken for medical care — including 10 with serious injuries.
About two hours after the accident, a U.S. official who was briefed on the investigation said he was told at least six people were killed. The official said he had no new information to explain the discrepancy in the numbers.
The official was not authorized to discuss the investigation publicly and spoke to The Associated Press on condition of anonymity.
A track chart prepared by the Washington State Department of Transportation shows the maximum speed drops from 79 mph (127 kph) to 30 mph for passenger trains just before the tracks curve to cross Interstate 5, which is where the train went off the tracks.
