In 1876, it bought part of the New York and Oswego Midland Railroad's Auburn Branch, extending from Freeville on the Utica, Ithaca and Elmira Railroad to Scipio, and was operated by the UI&E.
[1] On November 2, 1889, the line between Auburn and Dougal Road was bought at foreclosure by the Lehigh Valley subsidiary Auburn and Ithaca Railway, which built a line diverging from the IA&W at Genoa Junction (just west of Auburn) to Cayuga Junction on the Geneva and Sayre Railroad, another subsidiary.
The rest of the line, however, was redundant to the Southern Central, and passed through sparsely settled and unprofitable country.
The small portion preserved by the Lehigh Valley was abandoned in 1971.
The grade from Genoa Junction to Mapleton is now a power line right-of-way.
