GATINEAU, QC, June 25, 2013 /CNW/ - A number of factors led to the
derailment of 10 empty tank cars on a Canadian Pacific Railway siding
just south of Innisfail, Alberta, on 21 April 2012. These are the
findings of an investigation report (R12C0051) released by the
Transportation Safety Board of Canada today. During the accident, one
of the tank cars was punctured and a small amount of glycol leaked out.
One of the derailed cars struck the lead locomotive of a second train,
which had come to a controlled stop to allow the accident train to
manoeuvre onto the siding.
The investigation found that there were no issues related to the
handling of the train. Citing a combination of factors including track
that was not level near the turnout and a mismatch in the height of
couplers between cars, the Board found that the wheels on the first
derailed car likely climbed over the rail and began a derailment that
involved 10 cars and a locomotive.
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.
