The Transportation Safety Board of Canada issued a recommendation, calling for Transport Canada to develop strategies to reduce the severity of derailments involving dangerous goods. The recommendation was issued as part of its investigation into the Feb. 2015 derailment of a Canadian National Railway crude oil unit freight train near Gogama, ON. Twenty-nine tank cars of petroleum crude oil derailed and 19 of these breached, releasing 1.7 million litres of product. The crude oil ignited, resulting in fires that burned for five days. There were no injuries. The TSB wants 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.
