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.
