The Transportation Safety Board of Canada (TSB) says a train that derailed near Field, B.C. on Monday, killing its three-person crew, began moving on its own.

The train was travelling west to Vancouver when it derailed near the Alberta-B.C. border at around 1 a.m. M.T., claiming the lives of conductor Dylan Paradis, locomotive engineer Andrew Dockrell and conductor trainee Daniel Waldenberger-Bulmer. All three men were from Calgary.

At a Tuesday morning news conference, TSB senior investigator James Carmichael said Canadian Pacific Railway (CP Rail) train 301 had been stopped with air brakes applied at Partridge, the last station before the entrance to the Upper Spiral Tunnel, for about two hours when “the train began to move on its own.”

“A change-off between crews had occurred at this station as the previous crew was closing in on their maximum hours of service,” he said. “The ‘occurrence crew’ had just arrived and boarded the train but were not yet ready to depart.

“We’re going to try and determine why the brakes didn’t stay in place.”

The train was composed of 112 covered hopper cars and three locomotives positioned at the front, middle and rear of the train. In total, 99 cars and two locomotives derailed.

After the crash, only 13 of the train cars remained on the tracks. The lead locomotive and some of the cars derailed on a curve before a bridge, coming to rest in a creek. Several of the derailed cars came to rest on an embankment. The remaining cars, including the mid-train locomotive, piled up behind.

Event recorder data from the lead locomotive isn’t yet in the possession of the TSB as the locomotive was severely damaged. Some data has been recovered from the tail-end locomotive and work is underway to get data from the mid-train locomotive.

“It is too early to say what the causes and contributing factors to this accident might be,” Carmichael said. Tweet This

Two TSB investigators remained at the site of the derailment Tuesday to collect data, examine the wreckage and conduct interviews.

Waldenberger-Bulmer’s twin brother, Jeremy, also worked at CP Rail as a conductor and said his career is what led Daniel to become a trainee. He said his brother started with CP in November and “loved the job so far.”

“We had big plans of living out our careers with CP Rail and retiring together to golf all over the world,” he said.
