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 Baltimore, which had benefited to some extent from the construction of the National Road early in the century, wanted to do business with settlers crossing the Appalachian Mountains. The railroad faced competition from several existing and proposed enterprises, including the Albany-Schenectady Turnpike, built in 1797, the Erie Canal, which opened in 1825, and the Chesapeake and Ohio Canal. 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, Maryland, opened in 1834. There it connected with Harper's Ferry, first by boat, then by the Wager Bridge, across the Potomac River into Virginia, and also with the navigable Shenandoah River.
The Pennsylvania Railroad, legal name The Pennsylvania Railroad Company also known as the "Pennsy", was an American Class I railroad that was established in 1846 and headquartered in Philadelphia, Pennsylvania. It was named for the commonwealth in which it was established. At its peak in 1882, the Pennsylvania Railroad was the largest railroad, the largest transportation enterprise, and the largest corporation in the world.
MARC is a commuter rail system in the Washington–Baltimore combined statistical area. MARC is administered by the Maryland Transit Administration (MTA) and operated under contract by Alstom and Amtrak on track owned by CSX Transportation (CSXT) and Amtrak. In 2022, the system had a ridership of 2,815,900, or about 11,800 per weekday as of the first quarter of 2023, less than pre-COVID-19 pandemic weekday ridership of 40,000.
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 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 that operated independently from 1836 to 1881.
The Baltimore and Philadelphia Railroad was a railroad line built by the Baltimore and Ohio Railroad (B&O) from Philadelphia, Pennsylvania, to the Maryland-Delaware state line, where it connected with the B&O's Philadelphia Branch to reach Baltimore, Maryland. It was built in the 1880s after the B&O lost access to its previous route to Philadelphia, the Philadelphia, Wilmington and Baltimore Railroad (PW&B). The cost of building the new route, especially the Howard Street Tunnel on the connecting Baltimore Belt Line, led to the B&O's first bankruptcy. Today, the line is used by CSX Transportation for freight trains.
The Pittsburgh and West Virginia Railway was a railroad in the Pittsburgh, Pennsylvania, and Wheeling, West Virginia, areas. Originally built as the Wabash Pittsburgh Terminal Railway, a Pittsburgh extension of George J. Gould's Wabash Railroad, the venture entered receivership in 1908 and the line was cut loose. An extension completed in 1931 connected it to the Western Maryland Railway at Connellsville, Pennsylvania, forming part of the Alphabet Route, a coalition of independent lines between the Northeastern United States and the Midwest. It was leased by the Norfolk and Western Railway in 1964 in conjunction with the N&W acquiring several other sections of the former Alphabet Route, but was leased to the new spinoff Wheeling and Lake Erie Railway in 1990, just months before the N&W was merged into the Norfolk Southern Railway.

The Northern Central Railway (NCRY) was a Class I Railroad connecting Baltimore, Maryland with Sunbury, Pennsylvania, along the Susquehanna River.

The CSX Susquehanna River Bridge is a railroad bridge that carries CSX's Philadelphia Subdivision across the Susquehanna River between Havre de Grace and Perryville, Maryland, via Garrett Island. It was built in 1907-10 by the Baltimore and Ohio Railroad (B&O) on the same alignment as an 1886 B&O bridge. Like its predecessor, it was the longest continuous bridge on the B&O system.
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.

The line is currently operated by CSX Transportation as part of its Baltimore Terminal Subdivision.
