Ingenio San Agustin 2-8-0 Locomotives in Cuba


Class Details by Steve Llanso of Sweat House Media

Class 3 (Locobase 11708)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 16, p. 147. Works numbers were 11375-11376 in November 1890.

The Central San Agustin for which these little (tiny, practically HO) Consolidations were ordered was the skinniest of several Cuban plantation railroads so named in the late 19th Century. The light rail (30-45 lb/yard) wound some 31 1/4 miles near Las Lajas.
