An unattended 74-car freight train carrying Bakken Formation crude oil rolled down a 1.2% grade from Nantes and derailed downtown, resulting in the fire and explosion of multiple tank cars. Forty-two people were confirmed dead, with five more missing and presumed dead. More than 30 buildings in the town’s centre, roughly half of the downtown area, were destroyed, and all but three of the thirty-nine remaining downtown buildings had to be demolished due to petroleum contamination of the townsite. Initial newspaper reports described a 1-kilometre (0.6 mi) blast radius.
