A relatively small, regional railroad, the Dakota Minnesota and Eastern, has a bold plan to expand its range. The proposal takes the DM&E into the Powder River Basin coal fields and requires more than 250 miles of new track in Western South Dakota and Eastern Wyoming. Opponents have sprung up along that new section of railway. They are ranchers concerned about tracks cutting through their land and Native Americans who say the project will trample all over treaty rights. As our series "Tracking the Plains" continues, South Dakota Public Radio's Joshua Welsh reports another point of opposition may be found just under the surface of the ground.
