Class Details by Steve Llanso of Sweat House Media

Class 5 (Locobase 13740)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 36, p.196. See also Willis Fletcher Johnson, The History of Cuba, Volume 5 (New York: B F Buck & Company, 1920), pp. 179-180 and Alan Dye, Cuban sugar in the age of mass production: technology and the economics of the Sugar Central 1899-1929 (Stanford, Calif: Stanford University Press, 1998), p.92. Works number was 35462 in October 1910.

Andres Gomez-Mena owned two Centrales in the southeastern part of Havana Province; these were dubbed Amistad and Gomez-Mena and had been developed from an area that included swamp land below and almost arid terrain above. The solution, according to a 1920 account, was to drain the swamps and irrigate the highlands.

Sugar-plantation Moguls like the 5 were often bought for the Centrales by dealers. In this case, the company was Czarnikow Rionda & Co. See its biography at [], last accessed 16 January 2012.

Central Amistad would be the first Central introduce multiple milling in 1914 and substantially upgrade grinding efficiency. Gomez-Mena sold both of those Centrales in 1920 to Warner Sugar Refining Company of New Jersey for $16,000,000.


Class 6 (Locobase 14811)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Vol 64, pp. 20. Works numbers were 53822-53823 in October 1920.

Warner Sugar Company, which had bought the Gomez Mena processing mills in 1920, also bought these two oil-fired plantation Moguls as one of its first acts. They were a bit bigger than the 5 that had served the two Centrals for a decade (see Locobase 13740). 6 was later sold to the Central San Antonio, which was renamed after the 1959 Revolucion and 14811
