A high-speed Amtrak train derailed in Washington state Monday morning in what law enforcement is calling a “mass casualty” event.
According to officials, the train left Tacoma, Washington, Monday morning heading southbound. At least three cars derailed from an overpass above Interstate 5 near Dupont, Washington, around 7:40 a.m. local time.
One witness told CNN that a passenger train car had “crushed” vehicles on the road below, and that railcars had fallen off both sides of the track. According to law enforcement, no one on the ground was killed. “Multiple people” riding in the train were killed, according to officials.
The train is believed to have been on its maiden run of a new high-speed service on the route. It was headed south to Portland, Oregon.
Facts about Amtrak
Amtrak was created by Congress in 1970 to take over the intercity passenger rail services previously operated by private railroad companies in the United States. Operations began on May 1, 1971.
The name "Amtrak" results from the blending of the words "America" and "track." The railroad is officially known as the National Railroad Passenger Corporation.
In 2016, 31.3 million customers used Amtrak. On an average day, nearly 85,700 passengers ride more than 300 Amtrak trains.
Amtrak is a federally chartered corporation, with the federal government as majority stockholder. The board is appointed by the president of the United States and confirmed by the U.S. Senate. Amtrak is operated as a for-profit company, rather than a public authority.
Amtrak is the only railroad in North America to maintain right-of-way for service at speeds in excess of 125 mph (201 kph), and its engineering forces maintain more than 350 miles of track for 100+ mph (160+ kph) service.
