Medium-sized, well-traveled Vauclain compound Eight-wheeler with a small grate that soon was rebuilt with 18" x 24" simple-expansion cylinders. In 1902, #1 went to the Pittsburgh, Johnstown, Ebensburg & Eastern, the Buffalo & Susquehanna in 1903, where it operated for 14 years before being disposed of to the locomotive rebuilder/reseller Southern Iron & Equipment, which sold it to the Bonlee & Western.
