Warrenton 0-4-4 "Forney" Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class 3 (Locobase 12967)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 21, p.268. See also Roy V Wright (Ed.) 1912 Locomotive Cyclopedia of American Practice, Sixth Edition (New York: Simmons-Boardman Publishing Company, 1912), p. 158. Works number was 27916 in April 1906.

This little 3-mile line connected Warrenton with the Raleigh & Gaston Railroad. It was built in preference to allowing the R & G to run through the town itself. Opened in 1884, it offered passenger service for part of its time, while freight service continued to be available until 1985.

The 3 was sold in 1924 to locomotive rebuilder/reseller Southern Iron & Equipment. The SI & E sold the engine to Enterprise Whiteville Lumber Company as their #1.
