The Pennsylvania Railroad was an American Class I railroad that was established in 1846 and was headquartered in Philadelphia, Pennsylvania. It was so named because it was established in the Commonwealth of Pennsylvania.
The Northeast Corridor (NEC) is an electrified railroad line in the Northeast megalopolis of the United States. Owned primarily by Amtrak, it runs from Boston through Providence, New Haven, New York City, Philadelphia, Wilmington, and Baltimore to Washington, D.C. The NEC closely parallels Interstate 95 for most of its length, and is the busiest passenger rail line in the United States both by ridership and by service frequency as of 2013. The NEC carries more than 2,200 trains daily.
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 Richmond, Fredericksburg, and Potomac Railroad was a railroad connecting Richmond, Virginia, to Washington, D.C. The track is now the RF&P Subdivision of the CSX Transportation system; the original corporation is no longer a railroad company.
The Junction Railroad was a railroad created in 1860 to connect lines west of downtown Philadelphia, Pennsylvania, and allow north-south traffic through the metropolitan area for the first time. The railroad consisted of 3.56 miles of double track and 5.3 miles of sidings. It owned no locomotives or rolling stock. The line connected the Philadelphia and Reading Rail Road line at the west end of the Columbia Bridge over the Schuylkill River, crossed the Pennsylvania Railroad line, ran parallel to Market Street, and turned south to connect with the Philadelphia, Wilmington and Baltimore Railroad at Gray's Ferry.
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 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 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 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 Harrisburg Subdivision is a railroad line owned by CSX Transportation in the U.S. state of Pennsylvania. The line is located in the city of Philadelphia, connecting Greenwich Yard and the Philadelphia Subdivision with the Trenton Subdivision along a former Pennsylvania Railroad line. Much of the Harrisburg Subdivision is the High Line or West Philadelphia Elevated along 31st Street over the 30th Street Station area.
The West Philadelphia Elevated, also known as the High Line or Philadelphia High Line, is a railroad viaduct in the western part of Philadelphia, Pennsylvania. The 8,140-foot (2,480 m) structure spans the railway lines of 30th Street Station, parallel to the main track of the station, in a north-south direction. The 1,045-foot (319 m) long approach made of brick arches is the longest brick bridge and probably even the longest brick building in the United States.
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 P&W Subdivision is a railroad line owned and operated by CSX Transportation, the Allegheny Valley Railroad (AVR), and the Buffalo and Pittsburgh Railroad (BPRR) in the U.S. state of Pennsylvania. The line runs from Rankin north through Pittsburgh to West Pittsburg along a former Baltimore and Ohio Railroad line, once the Pittsburgh and Western Railroad.
The Delaware Extension was a rail line owned and operated by the Pennsylvania Railroad in Philadelphia, Pennsylvania.
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 Amtrak Railroad Anacostia Bridge is a railway-only bridge that crosses the Anacostia River in Washington, D.C. It carries Amtrak's Northeast Corridor and MARC's Penn Line passenger rail traffic. The bridge was damaged by the 1933 Chesapeake–Potomac hurricane, causing the famous "Crescent Limited wreck".
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.
The RF&P Subdivision is a railroad line owned and operated by CSX Transportation. It runs from Washington, D.C., to Richmond, Virginia, over lines previously owned by the Pennsylvania Railroad and the Richmond, Fredericksburg and Potomac Railroad. The line's name pays homage to that railroad, which was a predecessor to the CSX.
The Alexandria Extension is a short rail line in Washington, D.C. and Prince George's County, Maryland. Its northern portion connects the Capital Subdivision to the RF&P Subdivision, allowing freight trains to avoid Downtown Washington. Its southern portion, the Shepherd Industrial Spur, extends south to Shepherds Landing, directly across the Potomac River from Alexandria, Virginia; service on this portion ended in 2001.
The Vandalia Railroad Company was incorporated January 1, 1905, by a merger of several lines in Indiana and Illinois that formed a 471-mile railroad consisting of lines mostly west of Indianapolis.
