DUPONT, Wash. (AP) — Authorities say a total of 13 train cars jumped the tracks Monday at 7:33-a.m, PST, in the Amtrak  deadly train derailment outside Seattle, south of the city.

The Amtrak train was making the first-ever run along a faster new route hurtled off an overpass and spilled some of its cars onto the highway below, killing at least six people.

Hospital officials say at least two people are in critical condition and 11 others are seriously injured.

Four hospitals say 50 people have been hospitalized but didn’t immediately report all of their conditions. At least one person was in surgery Monday.

Seventy-eight passengers and five crew members were aboard when the train moving at more than 80 mph derailed about 40 miles (64 kilometers) south of Seattle before 8 a.m.

Washington State Patrol spokeswoman Brooke Bova says the train had 12 cars and two engines traveling between Tacoma and Portland, Oregon.

Bova says five vehicles and two semitrailers underneath the train on Interstate 5 were hit when cars came off the tracks from above.

It wasn’t clear how many train cars fell onto the road Monday.

 

The Amtrak train running between Tacoma and Portland, Oregon, derailed south of Seattle as it was making its first run as part of a faster service that local authorities had warned could be dangerous.

The National Transportation Safety Board says it’s sending a team, with the first members arriving Monday afternoon.

Board member Bella Dinn-Zarr told reporters in Washington, D.C., that it’s too early to tell whether speed contributed to the accident.

 

The section of track where an Amtrak train derailed had just been upgraded as part of a $181 million project for a new faster route.

Sound Transit, the public transit system for the Seattle area, owns the track and oversaw construction of the upgrades.

Agency spokeswoman Kimberly Reason says extensive testing was done before the opening of the system Monday but didn’t immediately have further details.

Reason says the project rerouted Amtrak trains that had been taking a slower route along a BNSF Railway line.

Authorities say at least six people died when the train went off the track and sent some cars onto a highway below.
