19th century
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.[4] An existing Northern Central Railway branch line terminating at Owings Mills was used to connect into Baltimore.
The railroad was completed to Westminster in 1861 and Union Bridge in 1862. Further expansion was delayed because of the Civil War. Westward construction resumed in 1868 under Chief Engineer Joseph S. Gitt, and the line was completed to Hagerstown in 1872. This section became the East Subdivision. The company's first major car shops were established at Union Bridge.[5]
In 1873, the WM built its own line from Owings Mills to Fulton Junction in Baltimore, and obtained trackage rights from the Baltimore and Potomac Railroad (B&P) for the remaining two miles of the route eastward to Calvert Street Station (Later replaced by Union Station (which still later was called Penn Station)). It built a branch east of Union Station to Hillen Station, which opened in 1876 and became the company headquarters. The WM built a connection from Hagerstown to Williamsport, in order to access coal traffic from the Chesapeake and Ohio Canal.[5]
Under the leadership of company president John Mifflin Hood, the railway made its first extension into Pennsylvania by leasing a line from Edgemont, Maryland, to Waynesboro and Shippensburg. This line became the Lurgan Subdivision and was leased from the Baltimore and Cumberland Valley Railroad in 1881, and was connected to the Harrisburg and Potomac Railroad in 1886.[4]
A second route into Pennsylvania, the Hanover Subdivision, was acquired by the WM when it gained control of the Baltimore and Hanover Railroad, and the Gettysburg Railroad, in late 1886. This line connected to the WM main at Emory Grove, proceeded north to Hanover and Gettysburg, then southwest to connect again to the WM at Highfield, Maryland, near the Pennsylvania border. A branch from Porters to York, Pennsylvania was completed in 1893; this became the York Subdivision.[4]
The West Virginia Central and Pittsburgh Railway (WVC&P) began as a narrow gauge line in 1880, its name and gauge changed in 1881 and in the ensuing years it opened a huge swath of timber and coal territory in the Allegheny Highlands of West Virginia. The railroad was directly responsible for the creation of such towns as Davis, Thomas, and Parsons.
The WM established a connection with the B&O in 1892 with the opening of the Potomac Valley Railroad, controlled by WM, between Williamsport and Big Pool, Maryland. This connection brought a major increase in through-freight traffic.[5] Construction of an extension from Hagerstown to Cumberland began in 1903 and completed in 1906. This became the West Subdivision. To service the expanded system, the WM built a major shop complex at Hagerstown in 1909, with a roundhouse, machine shops and related facilities. Rail yards at Hagerstown were also expanded.[5]
The WVC&P established the Coal and Iron Railway (C&I) in 1899 to reach logging operations and a connection with the C&O Railway. The route left Elkins, West Virginia and the Tygart Valley River drainage by way of a tunnel under Cheat Mountain, followed the Shavers Fork river upstream and then the West Fork Greenbrier River down from its headwaters to Durbin in Pocahontas County, where it connected with the C&O Greenbrier Division.
20th century
The Fuller Syndicate, led by George Gould, purchased a controlling interest in the WM in 1902 and made plans for westward expansion of the system.[4] In 1904, the WM completed construction of a large marine terminal at Port Covington, on the Patapsco River in Baltimore, to support the Gould organization's expansion plans. The terminal facilities included coal, grain and merchandise piers, overhead cranes, eleven rail yards, warehouses, a roundhouse, a turntable and a machine shop. During the 1920s, rotary dumpers for coal and coke were installed, and a large grain elevator.[5]
Construction to Durbin was complete by 1903. With the acquisition of the WVC&P in 1905, the C&I became part of WM and this line became the Durbin Subdivision.[4]
In 1907, the syndicate acquired several railroad companies, including the George's Creek and Cumberland Railroad (GC&C), which had built a line west through the Cumberland Narrows, and then south to Lonaconing, Maryland.[4]
