The Western Maryland Railway (reporting mark WM) was a small American Class I railroad (1852–1983) that operated in 3 Southern US States, Maryland (Western Region), West Virginia (Eastern Region), and Pennsylvania (Southern Region) in the Allegheny Regions of the Appalachian Mountains. It was primarily a coal hauling and freight railroad, with a small passenger train operation until 1958 when the WM discontinued all of its passenger service. The railroad was headquartered in Baltimore, Maryland.
The WM became a property of the Chessie System holding company in 1973, although it continued independent operations until May 1975 after which many of its lines were abandoned in favor of parallel Baltimore and Ohio Railroad (B&O) lines.
In 1983, it was fully merged into the B&O, which later was also merged with the former Chesapeake and Ohio Railway into the Chessie System in 1987, which then merged with the Seaboard System to form CSX Transportation.
