Waterborne and Rail Transport of U.S. Crude Oil [PDF ebook] 
Elements and Issues

New sources of crude oil from North Dakota, Texas, and western Canada have induced new routes for shipping crude oil to U.S. and Canadian refineries. While pipelines have traditionally been the preferred method of moving crude overland, they either are not available or have insufficient capacity to move all the crude from these locations. While rail has picked up some of this cargo, barges, and to a lesser extent tankers, also are moving increasing amounts of crude in domestic trade. This book discusses the Waterborne and rail transport of United States crude oil.
