Guatemala Central 2-6-0 Locomotives in Guatemala


Class Details by Steve Llanso of Sweat House Media

Class 23 (Locobase 13622)

Data from Baldwin Locomotive Works Specification for Engines, as digitized by the DeGolyer Library of Southern Methodist University, Volume 27, p. 83. Works numbers were 24471-24473 in July 1904.

Wood-burning Moguls bound for the 3 1/2% ruling grades and 15-degree curves of this Central American railway. Later the road would be renamed the Guatemala Railway (and this trio renumbered 80-82) and still later the International Railway of Central America.
