Death toll grows to 37 in Canadian runaway train catastrophe

(CNN) -- The death toll grew to 37 on Tuesday as crews recovered two more bodies in last week's devastating train derailment in the Canadian town of Lac-Megantic, said Genevieve Guilbault, spokeswoman for the Quebec coroner's office.

An unmanned 73-car train that had been parked in the neighboring town of Nantes on July 6 suddenly rolled into motion after the engineer went to a hotel.

The train slammed into the center of Lac-Megantic, and tank cars full of oil exploded and burned in the heart of the commercial district.

The rail company said the train's engineer failed to set the brakes properly, but the engineer said he reported to managers that he set 11 hand brakes on the train cars before they broke away from their engines.
