The line was built by the West Virginia Central and Pittsburg Railway (WVC&P) in the 1880s, and originally ran between Cumberland, Maryland and Elkins, West Virginia. The WVC&P merged with the Western Maryland Railway (WM) in 1905. The WM abandoned portions of the line between the 1930s and 1970s.[3] The WM was merged into the Chessie System in 1973, and the latter merged into CSX Transportation in 1980.[4]
