Ohio River & Columbus 2-6-0 "Mogul" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class 500 (Locobase 12783)

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
