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.

The EMD SW1 is a 600-horsepower (450 kW) diesel-electric switcher locomotive built by General Motors' Electro-Motive Corporation between December 1938 and November 1953. Final assembly was at EMD's plant at LaGrange (McCook) Illinois. The SW1 was the second generation of 3,402 cu in (55.75 L) switcher from EMD, succeeding the SC and SW. The most significant change from those earlier models was the use of an engine of EMD's own design, the then-new 567 engine, here in 600 hp (450 kW) V6 form. 661 locomotives of this design were built, with a gap in production between March 1943 and September 1945 due to World War II.

Rail transportation in the United States consists primarily of freight shipments, with a well integrated network of standard gauge private freight railroads extending into Canada and Mexico. Passenger service is mainly mass transit and commuter rail in major cities. Intercity passenger service, once a large and vital part of the nation's passenger transportation network, plays a limited role as compared to transportation patterns in many other countries due to the advent and widespread popularity of jet airplanes on major U.S. routes, and the completion of the Interstate Highway System, which resulted in the sharp curtailment of passenger service by private railroads. The United States has the largest rail transport network size of any country in the world, at a total of approximately 160,000 miles (260,000 km).
