DUPONT, Wash. Careening around a curve at almost three times the speed limit, an Amtrak train derailed and hurled passenger cars off an overpass and onto rush hour traffic below killing three people and injuring more than 100 others.
felt a little bit of a jolt, and then at a certain point we could hear crumpling of the train car, and we were catapulted into the seats in front of us, passenger Chris Karnes said.
Yet Positive Train Control technology that automatically slows down and stops a speeding train wasn activated, much to the dismay of the NTSB official.
were able to get the information about the speed from a data recorder retrieved from the rear locomotive. But the front locomotive more difficult to access, Dinh Zarr said.
train engineer has not yet been interviewed, but the NTSB hopes to have all interviews completed the next day or so, Dinh Zarr said.
was installed in the segment of tracks where the derailment happened, but wasn operational yet. The target date to have it working was spring quarter of 2018, said Geoff Patrick, the spokesman for Sound Transit which owns tracks where the train derailed.
All the deaths were contained to the train, said Ed Troyer, the Pierce County Sheriff Office spokesman. in DuPont, about 20 miles south of Tacoma, near the Billy Frank Jr. Nisqually National Wildlife Refuge. One rail car dangled precariously over the highway.
Several motorists in vehicles that were struck by the fallen train cars suffered injuries, but no one on the road was killed, the sheriff office said. Five cars and two semi trucks were involved in the crash, Washington State Patrol spokeswoman Brooke Bova said at a news conference. Investigators will likely look at several factors including the track, human performance, operations and mechanics of the train.
These are the questions investigators will be asking about the derailment
Most of the route was graded for a maximum speed of 79 mph; the speed limit on the curve where the crash occurred is 30 mph, said Rachelle Cunningham with Sound Transit.
Witnesses said they saw the train traveling at a fast speed.
Daniel Konzelman, who was driving on Interstate 5 at the time, said the train and his car were of parallel and was going faster than us. the technology that automatically slows down and stops a train if it senses that it going too fast or might get into an accident, had been installed on the track, but wasn operational yet, said Geoff Patrick, Sound Transit spokesman.
For PTC to be fully operational, it needs to be installed in trains, because a computer system links the train cars and tracks together, he said. The target date for having the PTC operational for that segment of the track had been the second quarter of 2018.
Amtrak has equipped 49% of its locomotives and 67% of its tracks with PTC, according toFederal Railroad Administration datafrom the second quarter of 2017.
The biggest obstacle to PTC: cost.
In response to a 2008 head on collision that killed 25 people near Los Angeles, Congress passed a law ordering the nation railroads to adopt PTC by December 2015. But the railroad industry has opposed PTC because of its high cost and technological issues.
As 2015 came to a close, several railroad companies threatened to shut down services unless Congress gave them more time, maintaining the deadline wasn realistic given the complex technology.
So Congress extended the deadline, giving companies until December 31, 2018, with extensions up to 2020 if certain requirements are met.
The Association of American Railroads estimated that as of March 2017, freight railroads had spent $8 billion and passenger railroads $3.5 billion to meet the PTC mandate.
