Cardenas & Jucaro / Central Juragua 2-6-0 Locomotives in Cuba


Class Details by Steve Llanso of Sweat House Media

Class 62 (Locobase 12642)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 25, p. 114. See also Mary Elizabeth Speck, Let There be Candy for Everyone: The Politics of Sugar in Cuba, 1902-1952 (UMI Number 3343889, 2009); and "Locomotive Boilers with Combustion Chambers", Engineering News, Volume LVI, No 21 (22 November 1906), pp. 531-534.Works numbers were 21237-21238 in November 1902.

These locomotives were planned to burn "Cumberland Coal in very fine lumps."

Located 17 miles from Habana, Cardenas anchored a network that included a 104-mile branch to Santa Clara, 71 miles to Vaguaramas, 27 miles to Montalvo. Two other short spurs connected Maximo Gomez (14 miles out of Cardenas) with Itabo 13 miles distant and Altamisal (8 miles further out the Vaguaramas branch) to Macagua 20 miles off. A later extension reached Cienfuegos on the southwestern coast.

The C&J was acquired by the United Railways of Havana in 1906.


Class 64 (Locobase 12835)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 28, p. 124. See also "Locomotive Boilers with Combustion Chambers", Engineering News, Volume LVI, No 21 (22 November 1906), pp. 531-534.Works numbers were 26383-26384, 26423-26427, 26440-26441 in September 1905.

As the C&J was ordering its two Eight-wheelers (Locobase 12834), it ordered a nonet of Moguls with the same firebox and the same boiler fitted with tubes shorter by 12 inches. Maintenance certainly must have been easier with so many shared components. The "mushroom head" firebox used a D-head front composed of a flanged tube sheet and a flanged front plate that together moved the tube ends 5" (127 mm) away from direct contact with the firebox's fire.


Class Nicky (Locobase 13071)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 30, p. 155. Works number was 29740 in December 1906.

Many sugar growers operated Baldwin Moguls of this size, although none of the others was named "Nicky".
