Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 19, p. 30. Works number was 13804 in October 1893..
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. In 1924, the B & W sold it to Georgia Car & Locomotive, which scrapped it in October 1924.
