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 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.

SWP has been vital in the location of several new industries to Fayette and Westmoreland Counties in recent years.
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.
