Bloomberg is reporting that there is a resurgence in the use of railroads to transport oil produced out of the Bakken and Three Forks shales (see here - http://www.businessweek.com/ap/financialnews/D9LUG0RG0.htm). "Trains have quickly become a huge part in hauling crude from North Dakota's oil patch with producers shipping barrels to more profitable markets not served by pipelines." Very interesting.
