The Amtrak Cascades Train 501 left Seattle Monday morning at about 6:00 a.m., headed for Portland, on its inaugural trip. About 40 miles south of Seattle, at about 7:30 a.m., the train derailed on a bridge over Interstate 5, with some cars falling below.
The train was carrying about 80 passengers and seven crew members. On the freeway it landed, there were five vehicles and two semi-trucks damaged from the falling train cars and debris. About 100 people were taken to local hospitals, at least six train passengers have died.
The tracks are owned by Sound Transit, which managed recent track-upgrade work under an agreement with the Washington State Department of Transportation.
The cause of the derailment is under investigation. Bella Dinh-Zarr, a National Transportation Safety Board member, said at a Monday night news conference that information from the event data recorder in the rear locomotive showed the train was traveling at 80 mph in a 30 mph zone when it derailed at 7:34 a.m.
