Brakes compromised by ice in runaway train that killed worker
Transportation CN fatality New Brunswick Train
New Brunswick CN employee died in 2018

EDMUNDSTON, N.B. — A report into the 2018 death of a New Brunswick CN worker says the brakes of two runaway railcars were compromised by ice before the cars collided.
The Transportation Safety Board of Canada says two cargo cars running uncontrolled in opposite directions along tracks at a CN yard in Edmundston collided on the morning of Dec. 4.
The crash killed a conductor trainee who was trapped on the footboard of the locomotive.
Investigators concluded in the report released today that the two cargo cars, which rolled down a slight grade, had been temporarily left with only their emergency brakes engaged.
Ice, snow reduced brake effectiveness
The report says crew at the yard had believed the cars to be in a so-called “attended” state, adding that investigators discovered the effectiveness of the wheel brakes had been reduced because of ice and snow accumulation.
“The brake effectiveness…was reduced because of ice contamination on seven of its eight brake shoes,” the report says of one of the railway cars in its findings section.
The second car “was also compromised by the contamination of its brake shoes from snow and ice that had probably built up as it was moved through the yard,” the report adds.
CN Rail workers ratify agreement that focuses on employee fatigue
It says if the CN employees had suspected the cars to be “unattended,” they would have been required under railway regulations to apply hand brakes to both cars and to conduct brake tests.
The report notes that the safety board had issued a notice a month before the incident reminding CN employees to remove ice from the trains’ wheel brakes, a process referred to as “brake conditioning.”
The notice stated that snow and ice accumulation on breaking surfaces “can dramatically reduce the effectiveness of train brake systems.”
CN spokesman Jonathan Abecassis said in an email Tuesday that in response to the incident, the railway company has reinforced its securement requirements and has modified its winter operations.
“Safety is a core value at CN and it is a critical part of everything we do,” Abecassis said. “As such, we learn from every event on our network to make CN a safer railroad for our employees, the public and the communities where we operate.”
