The river has been used for transportation across the Allegheny Mountains, between the cities of Baltimore and Washington, D.C. in the east and Pittsburgh in the west. Two railroads followed the Casselman River from Meyersdale, Pennsylvania to Confluence. First is the B&O Railroad, running between Baltimore and Pittsburgh, which was completed in 1871, and is currently owned by CSX. Second is the Western Maryland Railway, which ran from Cumberland, Maryland to Connellsville, Pennsylvania. Although the Western Maryland was abandoned in the 1980s, the right-of-way has been converted into the Great Allegheny Passage, a rail trail bicycle and hiking path.
