In the Lac-Mégantic #rail #disaster on July 6, 2013, an unattended 73-car #MMA freight train carrying crude oil rolled down a 1.2% grade and derailed in the Canadian town Lac-Mégantic. Multiple tank cars exploded, killing 47 people and destroying roughly half of all buildings in the town centre. It is the deadliest #freight #train #accident in #Canada's history.
