Central Reforma / Cuba Railroad 4-6-0 Locomotives in Cuba


Class Details by Steve Llanso of Sweat House Media

Class 3 (Locobase 14018)

Data from DeGolyer, Volume 44, p. 264. Works number was 37172 in November 1911.

This relatively small standard-gauge Ten-wheeler served a sugar mill and its plantation in Caibarien Province.

After the 1959 Revolution, the Reforma was renamed the Central Marcelo Salada and the 3 was renumbered 1342.


Class 40 (Locobase 13004)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 29, p 175. Works numbers were 29081, 29115 in September 1906; 29333-29334 in October; 29391-29392 in November.

This sextet of Ten-wheelers for the Cuba Railroad featured a relatively long firebox that permitted a larger grate than usual. A specific instruction required "total outside width of firebox to be such as to allow of boiler being removed without disconnecting same [sic; Locobase thinks "firebox") and without removing expansion plates."

One detail caught Locobase's interest: the whistle was to be "deep-toned ...a low G."


Class 46 (Locobase 20192)

Data from "Catalogue 10036--Locomotives for Export", American Locomotive Company (New York City, April 1910), pp. 42-43. Works numbers were 41405-41410 in October 1906.

Baldwin supplied the first six 4-6-0s to this railroad in 1906 (Locobase 13004) and Dickson's Scranton Works put out the next half-dozen.
