Central Pilar / Central Providencia 2-6-2 Locomotives in Cuba


Class Details by Steve Llanso of Sweat House Media

Class 1 (Locobase 12729)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 27, p 157. Works number was 24839 in November 1904.

Locobase was momentarily confused when he found orders for two locomotives for the same railroad, each of which was to be numbered 1. The other #1 is shown in Locobase 12727 and it operated on the CP's sugar-cane 30-inch railway. The current #1 was intended for standard-gauge service. It certainly wasn't a very big locomotive for its gauge, but it was still in existence in 1996.


Class Domingo Leon (Locobase 14845)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 64, pp. 95. Works number was 53594 in August 1920.

As with his other properties, the locomotives operating on this Central's railway (located near Gaspar in Camagney Province) bore the name of the head of the Compania Azucarera Central, Senor Domingo Leon. So this plantation Prairie joined the others in being so decorated.
