Few will forget that horrific day, July 6, 2013, when a crewless, runaway Montreal, Maine & Atlantic crude oil train with five locomotives and 75 loaded DOT-111 tank cars carrying volatile Bakken crude rolled into Lac-Mégantic, Quebec and derailed. The resulting fireballs and explosions (contrary to popular belief, the derailed cars did not explode; their contents ignited after the tanks had been breached) killed 47 people, and a large section of the downtown area was destroyed. The tragedy’s aftermath, as well as accidents involving other CBR trains in the U.S. and Canada, led to a long regulatory process resulting in the stronger DOT 117 tank car as well as several changes to CBR operating regulations.
