Class Details by Steve Llanso of Sweat House Media

Class Carmita (Locobase 14175)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 49, p. 44. Works number was 40540 in September 1913.

This was one of the smallest Consolidations to operate on the 3-ft gauge. Five axles spread the engine's weight over a longer section of 40 lb/yard (20 kg/metre) rail.
