Central San Isidro / Central Santa Isabel 2-8-0 "Consolidation" Type Locomotives

Class Details by Steve Llanso

Class 1 (Locobase 14029)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 44, p. 318 and Vol 64, p. 139. Works numbers were 40224 in July 1913, 52262 in August 1919, and 53864 in October 1920.

This plantation Consolidatoin was ordered by Beguiristain Jose Maria for the San Isidro (more formally, the "Ingenio San Isidro Destileria el Infierno") in Quemado de Guines Province. Six years later, Baldwin produced a nearly identical engine, this time for an order from Compania Azucarera de Sagua. The two changes included increased weight--a 1,500 lb (680 kg) increase in adhesion weight and 2,000 lb (907 kg) in engine weight-- and the more significant switch to oil fuel. The tender now held 1,000 US gallons (3,785 litres) of heavy crude. A second oil-burner arrived a little more than a year later.

The 1 and 12 later operated on the Central Andreita. After the 1959 Revolution, the azucarera took the name Central Mal Tiempo and the 1 was renumbered 1321 and 12 took 1355. 10 remained on the San Isidro, gaining number 1347 when the mill was renamed for Osvaldo Sanchez.

Class 1 (Locobase 14871)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Vol 64, p. 165. Works numbers were 53763 in September 1920 and 53953 in November.

These two stock Baldwin plantation Consolidations came to the Santa Isabel directly from Baldwin and were coal-burners. A third, oil-burning sister took a less direct route; see Locobase 14844.

Class ??? (Locobase 14844)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Vol 64, p. 167. Works number was 54214 in December 1920.

Unlike the earlier two Baldwin plantation Consolidations, this engine was not directly delivered to the CSI. It was in fact ordered by Central Caribe as their #1, but the oil-burner was instead diverted to the Central Guira. This Central was at that moment on the brink of foreclosure, so Eddystone secured a third buyer in the Santa Isabel, which had ordered its two coal burners of identical design only months before (Locobase 14871).

Santa Isabel, then located in Santa Clara Province (renamed Las Villas Province in 1940), was nationalized after the 1959 Revolucion and renamed for Ramon Ponciano.
