A train carrying tank cars oil rolled out of control in Lac-Megantic, Quebec, on July 6, exploding in an inferno that killed at least 35 people. This is Canada's worst railway catastrophe in almost 150 years.
Lac-Megantic's devastated downtown remained dangerous for days after the crash as responders put out fires and struggled to keep the remaining oil tankers cool so they wouldn't explode. The hazardous conditions delayed the search for people missing -- and now for bodies. 24 people are confirmed dead and 30 more are missing.
Edward Burkhardt, the head of the train's U.S.-based parent company, blamed the engineer for failing to set the brakes properly before the unmanned Montreal, Maine & Atlantic Railway train hurtled down a seven-mile incline, derailed and ignited in the center of Lac-Megantic early Saturday.
