The Aliquippa and Ohio River Railroad (reporting mark AOR) is a six-mile short line railroad in Aliquippa, PennsylvaniaUnited States, controlled by Genesee & Wyoming Inc. through its ownership of the Ohio Central Railroad System. It lies between CSX Transportation's ex-Pittsburgh and Lake Erie Railroad line and the Ohio River, extending south from CSX's yard in northern Aliquippa to near the Ambridge-Aliquippa Bridge. Formerly known as the Aliquippa and Southern Railroad (reporting mark ALQS), its owner and primary customer was LTV Steel, which mostly closed its Aliquippa plant in 1985 and sold the line to the Ohio Central in 2002. The AOR now connects the Aliquippa Industrial Park, which occupies the LTV site, with CSX.
