SUDBURY, Ont. – The Transportation Safety Board of Canada (TSB) is calling for Transport Canada (TC) to study the factors that increase the severity of outcomes of derailments of trains carrying dangerous goods and develop new strategies to reduce potential disaster. The recommendation came alongside a new TSB report, published on Feb. 16, on a derailment of a Canadian National train carrying petroleum crude oil near Gogoma, Ont. on Feb. 14, 2015. When 29 of the train’s 100 tank cars derailed that day, 19 of them spilled 1.7 million litres of crude, igniting fires that burned for five days, the report stated. The TSB investigation determined that failure of the track’s joint bars had contributed to the derailment. The train was moving at well below TC’s maximum allowed speed at the time. “The current speed limits may not be low enough for… unit trains carrying flammable liquids,” TSB chair Kathy Fox said at a press conference in Sudbury on Feb. 16. “We are also calling for Transport Canada to look at all of the factors, including speed, which contribute to the severity of derailments, to develop mitigating strategies and to amend the rules accordingly.” No one was injured in the 2015 derailment.
