PMG Graded Bond, 58 EPQ Choice About Uncirculated. The Western Maryland Railway (reporting mark WM) was an American Class I railroad (1852"1983) which operated in Maryland, West Virginia, and Pennsylvania. It was primarily a coal hauling and freight railroad, with a small passenger train operation. The WM became a property of the Chessie System holding company in 1973, although it continued independent operations until May 1975 after which time many of its lines were abandoned in favor of parallel Baltimore and Ohio Railroad lines. In 1983 it was fully merged into the Baltimore & Ohio Railroad, which later was also merged with the former Chesapeake and Ohio Railroad into the Chessie System in 1987, which is now renamed as CSX Transportation. The original main line began with the chartering of the Baltimore, Carroll and Frederick Railroad in 1852, with the intent of building a rail line from Baltimore west to Washington County, Maryland. The Maryland General Assembly changed the name of the company to the Western Maryland Rail Road Company in 1853, and construction began from Owings Mills in 1857.
