In a new video report, Bomb Trains: The Crude Gamble of Oil by Rail, Vice News investigated the risk of crude oil–carrying trains exploding as they crisscross North America. That isn’t some hypothetical risk that could be realized down the road—it’s already happening. Last summer, forty-seven people were killed when an oil-carrying train exploded in a small town in Quebec, and in the year since, four more trains have gone up in flames in the U.S. and Canada. With so many train lines carrying oil through the hearts of American cities, Vice highlights safety concerns for urban areas and rural alike.

The problem may only get worse, the report suggests. “A continental oil boom and lack of pipeline infrastructure have forced unprecedented amounts of oil onto US and Canadian railroads,” Vice explained on its website. “With 43 times more oil being hauled along US rail lines in 2013 than in 2005, communities across North America are bracing for another catastrophe.” Vice also published a map to see if you live in a “’Bomb Train’ Blast Zone.” If you live in a city, chances are you do.
