According to CBS News, an Amtrak train derailed while crossing an overpass on Interstate 5 in Washington state near the city of Dupont. Images from drivers, news crews on the scene, and the Washington State Department of Transportation’s nearby traffic camera reveal several train cars went off the overpass with one now dangling down onto the highway, where all lanes of traffic have been stopped.
Local CBS affiliate KIRO 7 is also reporting that emergency personnel on the scene of the derailment are treating it as a “mass casualty incident.” The Associated Press notes that several “injuries and casualties” are being reported (with CNN later adding that at least three people have been killed).
Passengers who spoke with CBS News, as well as KING 5 reporter Alex Rozier, confirmed the train was the newly minted Amtrak 501 line, which reportedly departed with 70 passengers aboard. The new high speed service was only rated for a top speed of 79 mph in the vicinity of the derailment in Dupont. According to data made available by Amtrak’s real-time location service at the time of the accident, however, the train was traveling at 81 mph.
Chris Karnes, who was on the train when it derailed, told CBS News he “felt this rocking and creaking noise” just before the derailment:
“We had just passed the city of DuPont and it seemed like we were going around a curve,” Karnes said. “All of a sudden, we felt this rocking and creaking noise, and it felt like we were heading down a hill. The next thing we know, we’re being slammed into the front of our seats, windows are breaking, we stop, and there’s water gushing out of the train. People were screaming.”
