Illinois Steel - South Works 0-4-0 Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class 2 (Locobase 4214)

Data from "Recent Narrow Gage [sic] Locomotives for Heavy Service," Railroad Age Gazette, Vol XLV, No 12 (21 August 1908) article (pp. 755-758) covering three recent narrow-gauge engine deliveries. See also DeGolyer, Volume 31, p. 124. Works number was 32361 in December 1907.

This little saddle tank was, according to RAG, "a powerful locomotive for its type, equalling in weight and tractive force, many standard gage (sic) engines." Design limitations included height and weight bounds of 11 ft and 7 ft 1 in, respectively.

After serving Illinois Steel for over 40 years, the #2 was sold in April 1945 to Mexico's Fundidora de Fierro y Acero de Monterrey.
