In 2013, a runaway train with no crew, no lights, and 72 tank cars of crude oil tore into Lac Mégantic, Quebec — triggering Canada’s deadliest modern rail disaster.
At 1:14 a.m. on July 6th, 2013, a silent, unmanned train derailed on a curve in Lac Mégantic. The resulting firestorm — fueled by six million liters of volatile Bakken crude — leveled the downtown, claimed 47 lives, and left a permanent scar on the town and rail safety history.
In this An Ounce disaster case study, we break down the chain of mechanical failures, human decisions, and systemic weaknesses that led to the catastrophe — and the lessons still unlearned.
If you think the systems we rely on are fail safe, this story might change your mind.
