Allegheny Branch
railway line in Pennsylvania

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.
History
The Allegheny Valley Railroad completed its initial line between Pittsburgh, Pennsylvania, and the Kiskiminetas River in October 1855 for a distance of 29 miles (47 km). The line followed the east bank of the Allegheny River. A further 13 miles (21 km), completed on December 11, 1855, extended the line to the mouth of the Crooked Creek, south of Kittanning, Pennsylvania.
This brief starts where responsible research should: with the source description of “Allegheny Branch” as railway line in Pennsylvania. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as railway line in Pennsylvania. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Feb 9, 2026. The linked authority identifier is Q134874706. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1852, 1870, 1900 and 1855.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
