GATINEAU, QC, Jan. 22, 2013 /CNW/ - The Transportation Safety Board of
Canada (TSB) today released its investigation report (R11V0254) into
the 21 December 2011 main-track derailment of a Canadian National
freight train near Cariboo, British Columbia.
The freight train was travelling westward on the Nechako Subdivision
when the train's emergency brakes activated because of a broken wheel.
Nineteen loaded coal cars derailed near Cariboo, British Columbia.
There were no injuries.
The investigation determined that a wheel on one of the cars had
fractured and fallen inside the rails. Once the derailed wheel entered
a spiked section of track, the rail rolled over causing the derailment.
The investigation also found that there is an increased risk of wheel
failures during winter months when wheel deterioration happens quicker.
The TSB is an independent agency that investigates marine, pipeline,
railway and aviation transportation occurrences. Its sole aim is the
advancement of transportation safety. It is not the function of the
Board to assign fault or determine civil or criminal liability.
