The Maryland and Pennsylvania Railroad (reporting mark MPA), familiarly known as the "Ma and Pa", was an American short-line railroad between York and Hanover, Pennsylvania, formerly operating passenger and freight trains on its original line between York and Baltimore, Maryland, from 1901 until the 1950s. The Ma and Pa was popular with railfans in the 1930s and 1940s for its antique equipment and curving, picturesque right-of-way through the hills of rural Maryland and Pennsylvania. Reflecting its origin as the unintended product of the merger of two 19th-century narrow gauge railways, the meandering Ma and Pa line took 77.2 miles (124 km) to connect Baltimore and York, although the two cities are only 45 miles (72 km) apart in a straight line.
Passenger service was discontinued on August 31, 1954, and the section from Baltimore to Whiteford, Maryland (just south of the Mason-Dixon line demarcating the Pennsylvania-Maryland border) was abandoned in June 1958. Most of the remaining original railroad line was abandoned by 1984. The Maryland and Pennsylvania Railroad acquired a former 19-mile (31 km) Pennsylvania Railroad (PRR) branch line between York and Hanover in the 1980s, now operated by a successor corporation, York Railway.
The Maryland and Pennsylvania Railroad was formed from two earlier 19th-century 3 ft (914 mm) narrow gauge railways: the Baltimore & Delta Railway, later the Baltimore & Lehigh Railway, and the York and Peach Bottom Railway, later the York Southern Railroad. Construction of the Baltimore & Delta Railway started in 1881, and passenger trains between Baltimore and Towson, Maryland began on April 17, 1882. Later that year the company was merged into the Maryland Central Railroad. The line was extended northward to Bel Air, Maryland on June 21, 1883, and the following January, the line was completed to Delta, Pennsylvania.
