"A train loaded with crude oil rolls past the Shenango Inc. coke works near Pittsburgh, PA. The U.S. Environmental Protection Agency describes coke oven emissions as ""among the most toxic of all air pollutants."" The train is carrying crude oil from the Bakkan oil field in North Dakota. These trains have derailed numerous times across the U.S. causing extreme air and water pollution. The oil they carry will be burned for energy, causing further release of fine particulates. The trains themselves become air polluters along the route.  © Scott Goldsmith/TDW 2015"
