Central Naranjal / Central Narcisa 2-8-0 Locomotives in Cuba


Class Details by Steve Llanso of Sweat House Media

Class 3 (Locobase 14924)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Vol 64, p. 367. Works number was 53800 in October 1920.

This oil-burning plantation Consolidation was ordered as one of a pair by the CN, which sold the other one to the Central Miranda (Locobase 14923). The 3 remained with this mill, which presented a profile that included 1 1/4% grades and curve radii as tight as 461 feet (140.5 metres).


Class Don Alvaro (Locobase 12826)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 28, p. 87. Works number was 26253 in August 1905.

A plantation Consolidation, this engine was later sold to another plantation line, the Central Obdulio Morales.


Class Lina (Locobase 14020)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 54, p. 182. Works number was 44065 in September 1916.

Although lettered for the Caibarien a Moron, the Lina originally served on this oddly gauged Central., which ran on 40-lb/yard (20-kg/metre) rails, scaled 2-3% grades and curves as tight as 24 degrees curvature (74 metre/242-ft radii). A note in the specs says that the engine was to be designed to allow conversion to the 3-foot gauge later if necessary. Locobase notices that the boiler tubes were to be electrically welded in the back tube sheet and that the firebox was to be set "above back frame rails so all staybolts can be repaired without removing slab frames."
