Much of the original WM west of Big Pool has been abandoned including the summit of the Allegheny Mountains and the Eastern Continental Divide near Deal, Pennsylvania. In addition to CSX, portions of the former WM are now operated by Durbin & Greenbrier Valley Railroad, the Maryland Midland Railway (MMID), Western Maryland Scenic Railroad, Pennsylvania & Southern Railway and York Railway. A portion of the former WM roadbed in Baltimore is now used by the Baltimore Metro Subway going northwest from downtown to Owings Mills, Maryland in Baltimore County.
