U.S. safety inspectors probing the deadly wreck of a passenger train that careened off a bridge onto a highway in Washington state are eager to question the engineer and a conductor-in-training who were in the cab of the locomotive, officials said on Tuesday.
National Transportation Safety Board (NTSB) officials hoped interviews with all crew members would shed light on why Train 501 on Amtrak’s Cascades line was going more than twice the speed limit around a curved stretch of track when it derailed on Monday.
The accident occurred during the train’s inaugural run on a new, slightly quicker route between Olympia and Tacoma, with 86 people aboard, 80 of them passengers, Amtrak said.
NTSB officials said they planned to interview all the crew members in the next two days, once they sufficiently recover from injuries suffered in the wreck, including the conductor-in-training who was with the engineer at the time.
Safety board member T. Bella Dinh-Zarr told reporters that NTSB investigators would seek to determine, among other factors routinely examined, whether the engineer was distracted while driving the ill-fated train.
“Distraction is one of our most-wanted-list priorities at the NTSB,” she said.
She also said investigators had determined that the train’s emergency brakes were automatically activated while the derailment was occurring, rather than engaged manually by the engineer.
In addition, she confirmed that a safety system known as positive train control (PTC), which automatically slows trains if they go too fast, was not installed on the rail line. She said Congress had extended a mandatory deadline for having the PTC system installed on all passenger railways to 2018.
None of the crew has been identified. All were hospitalized, Dinh-Zarr said.
Three people aboard the train were killed when all 12 carriages and one of the train’s two locomotives tumbled off the rails onto Interstate 5 near the town of DuPont, about 50 miles south of Seattle, officials said. Another 100 people were taken to hospitals, 10 with serious injuries.
Some motorists were among the injured, though nobody on the highway died.
Recorded data recovered from the rear locomotive showed the train was going 80 miles (129 km) per hour on a bend in the track where the speed limit was 30 mph (48 kph), NTSB officials said on Monday night. The board said it was investigating whether other circumstances besides speed were involved, such as track conditions, signals, mechanical issues and human factors.
Speaking at an afternoon news conference on Tuesday, Dinh-Zarr said that a conductor “who was getting experience and familiarizing himself with the territory” was present in the locomotive cab with the engineer. NTSB spokesman Peter Knudson described that second Amtrak employee as a “conductor-in-training.”
