The engineer of an Amtrak Cascades Service train that derailed on Monday near Olympia, Washington, may have been distracted shortly before that accident that left three passengers dead.
Federal investigators have said the train was traveling 80 mph in a 30 mph zone and left the tracks where the route curves to cross Interstate 5.
The distraction may have been caused by the presence of an employee in the lead locomotive who was being trained.
Investigators are focusing on why the engineer lost situational awareness.
National Transportation Safety Board member Bella Dinh-Zarr said that the train’s emergency brakes were activated automatically and not manually set off by the engineer
Dihn-Zarr said that skid marks from the train’s wheels show where it left the tracks.
However, Dinh-Zarr said investigators still have not concluded why the train derailed or why it was going too fast.
Investigators plan to interview the engineer and other crew members as well as review the event data record from the lead locomotive and an engine on the rear of the train. They also will seek to get images from two on-board cameras that were damaged in the crash.
The second person in the cab of the Charger locomotive was described as a conductor trainee making a trip to become familiar with the route.
Cascades Service No. 501 was making Amtrak’s first revenue service trip over the Point Defiance Bypass.
Officials have not identified the engineer, but he was bleeding from the head after the crash and his eyes were swollen shut.
No. 501, which was traveling from Seattle to Portland, Oregon, had 85 passengers and crew members aboard at the time of the crash. More than 70 people were injured in the derailment of which 35 were hospitalized, 21 of them in critical or serious condition.
Dinh-Zarr said Amtrak crew members had been making test runs over the route for two weeks before scheduled service on it began. The route is owned by Sound Transit and had recently been rebuilt.
Two of the victims were identified as passenger rail advocates Jim Hamre, a retired civil engineer with the Washington State Transportation Department; and Zack Willhoite, a transit agency customer service employee. Both were members of All Aboard Washington.
In the meantime, Amtrak has resumed operating between Seattle and Portland over its previous route.
Cascades No. 502, the morning run from Portland to Seattle, was canceled but trains were to run as scheduled.
It is now known how long it will be before Amtrak can resume using the Port Definance Bypass. In the interim, Amtrak will also use is former station in Tacoma at 1001 Puyallup Ave.
