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 benefited 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 Albany-Schenectady Turnpike built in 1797, and the newly constructed Erie Canal, opened in 1825,, 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.
The B&O Railroad Museum is a museum exhibiting historic railroad equipment in Baltimore, Maryland, originally named the Baltimore & Ohio Transportation Museum when it opened on July 4, 1953. It has been called one of the most significant collections of railroad treasures in the world and has the largest collection of 19th-century locomotives in the U.S. The museum is located in the Baltimore and Ohio Railroad's old Mount Clare Station and adjacent roundhouse, part of the B&O's sprawling Mount Clare Shops site begun in 1829, the oldest railroad manufacturing complex in the United States.
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 Philadelphia, Wilmington and Baltimore Railroad (PW&B) was an American railroad that operated from 1836 to 1881. Formed as a result of the merger of four small lines dating from the earliest days of American railroading in the late 1820s and early 1830s, it was purchased by the Pennsylvania Railroad (PRR) in 1881, becoming part of their main line in 1902.
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.
Tom Thumb was the first American-built steam locomotive to operate on a common-carrier railroad. It was designed and constructed by Peter Cooper in 1829 to convince owners of the newly formed Baltimore and Ohio Railroad (B&O) to use steam engines; it was not intended to enter revenue service. It is especially remembered as a participant in a mythical impromptu race with a horse-drawn car, which the horse won after Tom Thumb suffered a mechanical failure. However, the demonstration was successful, and the railroad committed to the use of steam locomotion and held trials in the following year for a working engine.
The Thomas Viaduct spans the Patapsco River and Patapsco Valley between Relay, Maryland and Elkridge, Maryland, USA. It was commissioned by the Baltimore and Ohio Railroad (B&O); built between July 4, 1833, and July 4, 1835; and named for Philip E. Thomas, the company's first president. It remains the world's oldest multiple arched stone railroad bridge.
The Patterson Viaduct was built by the Baltimore and Ohio Railroad (B&O) as part of its Old Main Line during May to December 1829. The viaduct spanned the Patapsco River at Ilchester, Maryland. It was heavily damaged by a flood in 1866 and subsequently replaced with other structures.
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 Belt Line was constructed by the Baltimore and Ohio Railroad (B&O) in the early 1890s to connect the railroad's newly constructed line to Philadelphia and New York City/Jersey City with the rest of the railroad at Baltimore, Maryland. It included the Howard Street Tunnel, the Mount Royal Station for B&O's Royal Blue Line passenger trains, and the first mainline railroad electrification in the United States. The line is currently operated by CSX Transportation as part of its Baltimore Terminal Subdivision.
The President Street Station in Baltimore, Maryland, is a former train station and railroad terminal. Built in 1849 and opened in February 1850, the station saw some of the earliest bloodshed of the American Civil War (1861-1865), and was an important rail link during the conflict. Today, it is the oldest surviving big-city railroad terminal in the United States. A preservation campaign and renovation project completed in 1997 enabled the station to be operated as the Baltimore Civil War Museum for several years. The museum is temporarily closed as of early 2021.
