1858 - THE WESTERN MARYLAND RAILROAD - $500

The Western Maryland Railway (WM signage) was an American Class I railway (1852–1983) operating in Maryland, West Virginia, and Pennsylvania. It was primarily a railroad for transporting and transporting coal, with a small passenger train.

WM became the property of the Chessie System holding company in 1973, although it continued to operate independently until May 1975, after which many of its lines were abandoned in favor of the parallel lines of Baltimore and Ohio Railroad. In 1983 it was fully merged with the Baltimore & Ohio Railroad, which was later merged with the Chesapeake and the Ohio Railroad into the Chessie System in 1987, which has now been renamed CSX Transportation.
