The Baltimore and Ohio Railroad was the first common carrier railroad and the oldest railroad in the United States, with its first section opening in 1830. Merchants from the city of Baltimore, which had benefitted to some extent from the construction of the National Road early in the century, wanted to continue to compete for trade with trans-Appalachian settlers with the newly constructed Erie Canal, another canal being proposed by Pennsylvania, the Chesapeake and Ohio Canal, and the James River Canal, which directed traffic toward Richmond and Norfolk, Virginia. At first the B&O was located entirely in the state of Maryland, its original line extending from the port of Baltimore west to Sandy Hook. There it connected with Harper's Ferry across the Potomac into Virginia, and also with the navigable Shenandoah River.
MARC Train Service, previously known as Maryland Rail Commuter, is a commuter rail system comprising three lines in the Baltimore–Washington metropolitan area. MARC is administered by the Maryland Transit Administration (MTA), a Maryland Department of Transportation (MDOT) agency, and is operated under contract by Bombardier Transportation Services USA Corporation (BTS) and Amtrak over tracks owned by CSX Transportation (CSXT) and Amtrak.
The Western Maryland Railway 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 Capital Subdivision is a railroad line owned and operated by CSX Transportation in the U.S. state of Maryland and the District of Columbia. The line runs from near Baltimore, Maryland, southwest to Washington, D.C., along the former Baltimore and Ohio Rail Road (B&O) Washington Branch. The subdivision's Alexandria Extension provides a connection to Virginia and points south.
The Baltimore and Potomac Railroad (B&P) operated from Baltimore, Maryland, southwest to Washington, D.C., from 1872 to 1902. Controlled by the Pennsylvania Railroad, it was the second railroad company to connect the nation's capital to the Northeastern States, and competed with the older Baltimore & Ohio Railroad.
The Philadelphia, Wilmington and Baltimore Railroad (PW&B) was an American railroad company itself a result of merger of four small lines dating from the earliest days of American railroading in the late 1820s and early 1830s, that operated from 1836, until being bought by a larger regional line in 1881, with a merger into a longer Northeast Corridor railway in 1902. It built the first rail line south from Philadelphia into The South.
The Northern Central Railway (NCRY) was a Class I Railroad connecting Baltimore, Maryland with Sunbury, Pennsylvania, along the Susquehanna River. Completed in 1858, the line came under the control of the Pennsylvania Railroad (PRR) in 1861, when the PRR acquired a controlling interest in the Northern Central's stock to compete with the rival Baltimore and Ohio Railroad (B&O). For eleven decades the Northern Central operated as a subsidiary of the PRR until much of its Maryland trackage was washed out by Hurricane Agnes in 1972; after which most of its operations ceased as the Penn Central declined to repair sections. It is now a fallen flag railway, having come under the control of the later Penn Central, Conrail, and then broken apart and disestablished. The southern part in Pennsylvania is now the York County Heritage Rail Trail which connects to a similar hike/bike trail in Northern Maryland down to Baltimore, named the Torrey C. Brown Rail Trail. Only the trackage around Baltimore remains in rail service.
The Old Main Line Subdivision is a railroad line owned and operated by CSX Transportation in the U.S. state of Maryland. The line runs from Relay west to Point of Rocks, and was once the main line of the Baltimore and Ohio Railroad, one of the oldest rail lines in the United States. At its east end, it has junctions with the Capital Subdivision and the Baltimore Terminal Subdivision; its west end has a junction with the Metropolitan Subdivision.
The Baltimore & Annapolis Railroad was an American railroad of central Maryland built in the 19th century. The railroad, the second to serve Annapolis, ran between Annapolis and Clifford along the north shore of the Severn River. From Clifford, just north of the present day Patapsco Light Rail Stop, it connected with the B&O's Curtis Bay branch so that trains could travel to Baltimore. In 1921, when it was called the Annapolis and Baltimore Short Line, it was purchased by the larger Washington, Baltimore and Annapolis Electric Railway (WB&A), and then emerged from the WB&A's 1935 bankruptcy and closure as the Baltimore & Annapolis Railroad. B&A electric passenger operation between the two cities continued until 1950, at which time the rail line became solely a freight carrier, operating buses for passenger service. Freight service to Annapolis continued until June 1968 when the Severn River Trestle was declared unsafe. In the 1980s the line was completely shut down. The right-of-way now serves as part of Baltimore's light rail system and as the Baltimore & Annapolis Trail.
The Metropolitan Subdivision is a railroad line owned and operated by CSX Transportation in the District of Columbia and the U.S. state of Maryland. The line runs from Washington, D.C., northwest to Weverton, Maryland, along the former Metropolitan Branch of the Baltimore and Ohio Railroad.
The Camden Line is a MARC commuter rail line that runs for 39 mi (63 km) between Union Station, Washington, D.C., and Camden Station, Baltimore, Maryland, over the CSX Capital Subdivision, and Baltimore Terminal Subdivision. It is one of the oldest commuter lines in the United States still in operation. The Baltimore & Ohio Railroad began running commuter service from Baltimore to Ellicott City over part of the current line's trackage on May 24, 1830, and the line was extended to Washington on August 25, 1835. The Camden Line is the shortest MARC line and along with the Brunswick Line, is the successor to commuter services operated by the B&O. As of 2019, the Camden Line is a weekday-only service.
The Pope's Creek Subdivision is a CSX Transportation railroad line in Maryland, running from Bowie to Morgantown where the Morgantown Generating Station is located and the Chalk Point Generating Station.
The Ellicott City Station in Ellicott City, Maryland, is the oldest remaining passenger train station in the United States, and one of the oldest in the world. It was built in 1830 as the terminus of the Baltimore and Ohio Railroad line from Baltimore to the town then called Ellicott's Mills, and a facility to service steam locomotives at the end of the 13-mile (21 km) run. The station, a National Historic Landmark, is now used as a museum.
The Bowie Railroad Buildings comprise three small frame structures at the former Bowie train station, located at the junction of what is now the Northeast Corridor and the Pope's Creek Subdivision in the town center of Bowie, Maryland. The complex includes a single-story freight depot, a two-story interlocking tower, and an open passenger shed. The station was served by passenger trains from 1872 until 1989, when it was replaced by Bowie State station nearby. The buildings were restored in 1992 as the Bowie Railroad Museum and added to the National Register of Historic Places in 1998.
The Washington, Baltimore and Annapolis Electric Railway (WB&A) was an American railroad of central Maryland and Washington, D.C., built in the 19th and 20th century. The WB&A absorbed two older railroads, the Annapolis and Elk Ridge Railroad and the Baltimore & Annapolis Short Line, and added its own electric streetcar line between Baltimore and Washington. It was built by a group of Cleveland, Ohio, electric railway entrepreneurs to serve as a high-speed, showpiece line using the most advanced technology of the time. It served Washington, Baltimore, and Annapolis, Maryland, for 27 years before the "Great Depression" and the rise of the automobile forced an end to passenger service during the economic pressures of the 1930s "Depression" southwest to Washington from Baltimore & west from Annapolis in 1935. Only the Baltimore & Annapolis portion between the state's largest city and its state capital continued to operate electric rail cars for another two decades, replaced by a bus service during the late 1950s into 1968. Today, parts of the right-of-way are used for the light rail line, rail trail for hiking - biking trails, and roads through Anne Arundel County.
The Baltimore Terminal Subdivision is a railroad line owned and operated by CSX Transportation in the U.S. state of Maryland. The line runs from Baltimore to Halethorpe along the original Baltimore and Ohio Railroad (B&O) line, one of the oldest rail lines in the United States and the first passenger railroad line. At its east (north) end, it connects with the Philadelphia Subdivision; its west (south) end has a junction with the Capital Subdivision and the Old Main Line Subdivision.
