Reading Blue Mountain and Northern 425 is a G-1 class 4-6-2 light "Pacific" type steam locomotive built by the Baldwin Locomotive Works for the Gulf, Mobile & Northern Railroad. After the GM&N was consolidated into the Gulf, Mobile & Ohio in 1940, the locomotive was renumbered No. 580 and served in passenger service before being retired in 1950. The locomotive is currently owned and operated by the Reading & Northern, based out of Port Clinton, Pennsylvania in excursion service. At the end of 2022, No. 425 was taken out of service for its mandatory Federal Railroad Administration (FRA) 1,472-day inspection and overhaul. It was expected to be returned to service around 2025.
