Hearing on train derailment zeroes in on curves

An Amtrak train derailed south of Tacoma in December.

But beyond questions about the engineer’s qualifications, National Transportation Safety Board officials raised concerns at an investigative hearing this week about how the problematic curve in the new Point Defiance bypass route fits into the larger narrative of derailments caused by dangerous curves.

Safety board officials were met with silence by a room full of agency officials responsible for the bypass where the derailment took place. Officials from Amtrak, Sound Transit, the Federal Railroad Administration and the Washington Department of Transportation could not answer a question about whose responsibility it was to mitigate problems with the curve that required trains traveling 80 mph to slow to 30 mph.

NTSB chairman Robert Zumwalt pointed to the 2015 Amtrak derailment in Philadelphia, another incident in 1990 at Boston’s Back Bay station and yet another near the Spuyten Duyvil station in New York City in 2013. Each of those incidents included dangerous curves.

“You would think that curves would be very much on the radar so to speak of a railroad these days,” Zumwalt said. “And so I’d love to see what you did to assess the risk associated with this.”

The curve near Tacoma, at around milepost 19 on the new bypass, has since been identified by the agency responsible for reviewing designs for the bypass as the one curve in the route that would particularly benefit from an automatic braking technology known as Positive Train Control, or PTC. The technology is meant to slow or stop speeding trains automatically.

The NTSB has advocated for the technology for years, with much resistance from railroads and freight companies that complained about the complex nature of the undertaking.

Congress pushed back a federal deadline requiring the installation of PTC on all Class I railroads to this December.

“Positive Train Control will help everywhere,” said Martin Young, program manager with Sound Transit. “But there was one curve in particular that will be helped. And that one is at (milepost) 19.8.”

Michael DeCataldo, Amtrak’s vice president of operations, said Amtrak has since strengthened the qualifications required for train operators.

Qualifications for operating on certain train routes will depend on the difficulty of the route. Locomotive engineers will be required to do a minimum of four round trips over an entire route before they can qualify to operate on the route.

The engineer operating the Amtrak 501 train had operated just one round trip over the new territory, telling the qualifying conductor that the Dec. 18 trip was “a learning experience for him,” according to investigative documents.

“Looking back, we have seen gaps in our qualification process and we will address those,” DeCataldo said.

NTSB has requested a review of medical records outlining predicted injuries on the train versus actual injuries. They’ve also asked the Washington Department of Transportation for safety documents needed to complete the federal grant used to pay for the new bypass.

Amtrak says its on track to implement PTC ahead of the December federal deadline. The bypass is expected to reopen this fall.
