Class Details by Steve Llanso of Sweat House Media

Class 3 (Locobase 13200)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 26, p. 28. Works number was 22726 in August 1903.

After work in the Brooklyn Navy Yard, the 3 moved on to the locomotive rebuilder/reseller Thomas F Cary. TFC sold the engine to rebuilder/reseller Southern Iron & Equipment, which removed the leading pony truck (thus making it an 0-4-2ST) and sold it in June 1922 to Riverside Lumber Company of Beach, Ga.
