Allegheny Branch

The Allegheny Branch, also known as the Allegheny Subdivision, is a partially-abandoned railway line in the United States. It was built between 1852 and 1870 by the Allegheny Valley Railroad as that company's main line. It became part of the Pennsylvania Railroad network in 1900. At its fullest extent the line ran 132 miles (212 km) between Pittsburgh, Pennsylvania, and Oil City, Pennsylvania. Today, the Allegheny Valley Railroad, unrelated to the original company, owns the section between Pittsburgh and Arnold, Pennsylvania, while a small section in Oil City belongs to the Norfolk Southern Railway and is leased by the Western New York and Pennsylvania Railroad. The remainder has been abandoned. Much of the former right-of-way has been converted to rail trails.
