Central Teresa / Central Tinguaro / Central Triunvira 2-6-0 Locomotives in Cuba


Class Details by Steve Llanso of Sweat House Media

Class 5 (Locobase 12833)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 27, p. 95, Volume 28, p. and Volume 31, p. 74 . Works numbers were 24565 in August 1904 and 26466 in August 1905.

The specs for these sugar-plantation Moguls stressed that the weight on the drivers be "...as much as practicable without total weight exceeding 104,000 lb." They would serve the 23 miles (37 km) of railway that connected the mill to Pijuan on one line and linke Climete and Zarabanda on another.

The mill, part of the Cuban American Sugar Company holding owned by R B Hawley, was located at Colón in Matanzas Province. It grew to be one of the biggest in Cuba. By the end of 1912, it reported itself ready to make between 170,000 and 175,000 sacks (27,625-28,437 short tons/25,114-25,852 tonnes) of sugar per year.


Class 6 (Locobase 14173)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 49, p. 40. See also United States General Staff, Military notes on Cuba (Washington, DC: US Government Printing Office, 1909), pp. 94-95. Works number was 40775 in October 1913.

Although also a sugar railroad in Cuba, this 14.4-mile (23.2-km), 3-foot gauge line is not the same as the Central Santa Teresa, which rolled on the smaller 2' 6"gauge. The CTR connected the wharf at Ceiba Hueca near Manzanillo with the CT sugar mill and on into the fields near Los Muchachos on the Tana River.

Broker Hugh Kelly arranged for the purchase of the 6.


Class 8 (Locobase 14901)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Vol 64, pp. 279. See also See also John Paul Rathbone, The Sugar King of Havana: The Rise and Fall of Julio Lobo, Cuba's Last Tycoon (New York: Penguin Press, 2010), esp. pp. Works numbers were 52204 in August 1919.

Rail weights had risen to 56 and 60 lb/yard (28 and 30 kg/metre) on the CT, considerably higher than in the days when the first Baldwin Moguls came on the line (Locobase 12833). The new engine put 4 tons more on the drivers, but concentrated that weight on a wheelbase measuring 3 feet (914 mm) less.

A standard oil-burning Baldwin plantation engine, the 8 later served the Unidad Sugar Company.

The Tinguaro was the favorite mill in Julio Lobo's sugar empire according to John Rathbone, who paints a fascinating word portrait of a sugar baron known for keeping in touch with the workers on his plantations and for his "scrupulous honesty". Describing the first meeting between Lobo the "arch capitalist" and Guevara, the "Stakhanovite"in October 1960, Rathbone presents the moment when Guevara reported that the Castro government's review of Lobo's accounts turned up "Not a stain, or a blemish", Lobo notes that it was to be expected. But Guevara then said, "Because of that, we have left you to last."

The nationalized CT would be renamed for Sergio Gonzalez.


Class Triunvirato (Locobase 12012)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 17, p. 176. Works number was 13080 in December 1892.

After working on the CV for some time, the 2 went to the North American Sugar Company, which later sold it to the Central Narcisa. That railroad rebuilt the engine to the 2' 9" gauge (or the 2' 7 1/2" gauge) and, as the Central Obdulio Morales, awarded it the grandly scaled 1227 as its road number.
