Bomb Trains on the Hudson

The sight of long trains, made up of one hundred-plus black, cylindrical cars, rolling slowly through cities and towns across North America – often within yards of office buildings, hospitals and schools -- has become commonplace. Few who see them know what these sinister-looking cars carry: A highly flammable mixture of gas and oil from the shale fields of North Dakota. At thirty thousand gallons per car, each of these trains carries more than three million gallons of highly flammable and toxic fuel.
