Yesterday, Canada’s Transportation Safety Board (TSB) concluded their investigation of the Lac-Mégantic, Quebec train derailment that occurred on July 5, 2013. According to the final report, the accident was caused by a runaway train carrying crude oil that was parked at the top of a hill for the evening, but upon its brakes failing, slid down the tracks and crashed near the center of town resulting in an explosion killing 47 people. The TSB determined that eighteen factors led to the catastrophe, but emphasized a “weak safety culture” as one of the major causes.
TSB found that the rail operator, Montreal, Maine & Atlantic Railway (MMA), which has since filed for bankruptcy, had a weak safety management system and lacked effective training and maintenance procedures. Their report also criticized the transportation ministry, Transport Canada, for a lack of management and regulation. The investigation found that Transport Canada was aware that MMA carried a higher risk of accidents in recent years due to an increase in the transportation of crude oil, yet performed few audits and failed to follow up when it uncovered problems.
The report recommends more comprehensive audits and improved technology to prevent runaway trains caused by brake failure. In January, the safety boards of Canada and the U.S. collaborated on suggestions to improve safety, given that crude oil transportation by train has increased considerably in the last ten years due to advanced technology and the subsequent shale boom. New Democrat Member of Parliament Hoang Mai has attributed the accident to the fact that “conservatives have left companies to monitor themselves,” and other opposition politicians have also blamed the federal government for the disaster.
