An Amtrak train carrying more than 250 passengers derailed on Sunday near Puget Sound in Washington .
Several passengers were injured but no one was believed to have been seriously hurt, the rail service reported.
The locomotive and baggage car of train 506 on the Amtrak Cascades line, running between Vancouver, British Columbia, and Eugene, Oregon, left the tracks at Chambers Bay Bridge in Steilacoom, Washington, just south of Tacoma, Amtrak said
From local news media images of the wreck it appeared that three or four cars of the train were derailed with the engine seen lying on its side a short distance from the shore of Puget Sound near the Chambers Bay Marina.
The cause of the accident was under investigation, said Amtrak.
“All passengers are being evacuated, and emergency responders are on the scene,” the train service said.
Travellers were being provided with alternate transportation.
