Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 27, p. 254. Works number was 25770 in May 1905.
Short-line OR&C only operated this long-lived Mogul for six years before selling it to the San Antonio & Aransas Pass in 1911. The SA & AP renumbered it 168 and ran it for 16 years before it was taken into the Texas & New Orleans
