Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Vol 66, pp. 290+ and 72, pp. 157+. Works numbers were 52689 in December 1919 and 57635 in February 1924.
Tiny wood-burning saddle tanks headed for the light rail (36 lb/yard//18 kg/metre) and tight curves (radii of 124 feet/37.8 metres) of a sugar plantation. The engines were topped by Rushton Improved spark-arresting cabbage stacks. The second one weighed 250 lb (113 kg) more than the first.
