Central San Agustin / Central San Antonio / Central Santa Amalia / Central Santa Ana 2-8-0 Locomotives in Cuba


Class Details by Steve Llanso of Sweat House Media

Class 2 (Locobase 14469)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 54, p 189. Works number was 43684 in July 1916.

After only a few years, the CSA sold this plantation Consolidation to the nearby Central Toledo, which was located at Marianao in Havana Province.


Class 4 (Locobase 15352)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 78, p. 46+. Works number was 58791 in October 1925.

Baldwin produced plantation Consolidation designs in several sizes and weights. This was one of the skinny-gauge engines that weighed about 29 tons ready for operation. The Baldwin spec included a long list of detail parts on page 48 that were to be packed separately and forwarded by ocean freight, most likely to avoid damage or loss if they remained on the engine.

The San Antonio, located at Madruga in La Habana Province, later sold the 4 to the Central Dos Rosas at Cardenas in Matanzas Province, where she may have been renumbered 9. The CDR was renamed after the 1959 Revolucion and expropriation for Humberto Alvarez. At that point, 4 was renumbered 1242


Class 5 (Locobase 15254)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Vol 72, p. 47+. Works number was 57972 in August 1924.

This oil-burning plantation Consolidation was a typical sugar-mill engine. It was later owned by the Central Sugar Company.


Class 6 (Locobase 13842)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Vol 39, p. 195 and Vol 64, pp. 124. Works numbers were 37081 in October 1910 and 52914 in January 1920.

The Ingenio San Agustin had a main line of 11 km (6.8 sm) rolling on rails weighing between 40-50 lb/yard (20-25-kg/metre). Whereas the 1910 locomotive burned coal, the 1920 trailed a bigger tender that held 1,500 US gallons (5,678 litres) of water and 800 gallons (3,028 liters) of heavy Tampico oil. Fully loaded, the new tender weighed 33,500 lb (15,195 kg).


Class Amalia Maria (Locobase 14867)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Vol 64, p. 157. Works number was 53801 in October 1920.

The CSA bought this stock oil-burning Baldwin plantation Consolidation at the same time its sister was supplied to the Central Progreso.


Class Angelina (Locobase 14468)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 54, p. 164. Works number was 43729 in July 1916.

There were two Centrales named San Agustin. The narrow-gauge railway that took delivery of this plantation Consolidation operated in Caibarien in Santa Clara Province. The line had 45 lb/yard (22.5 kg/metre) rail and 11 3/4-degree curves (radii of 492 ft/150 metres). Compared to several other 2-8-0s of about the same size, this design had a shallower firebox.


Class Digna (Locobase 14853)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 64, p 120. Works numbers were 52632 in December 1919 and 53846-53847 in October 1920.

By the time these plantation Consolidations arrived at its Santa Clara railway, the line had been improved. Now the lightest rail weighed 40 lb/yard (20 kg/metre), presented a maximum grade of 2.8% over a 4 kilometre (2.5 mile) run, and minimum curves bending a gentler 200 metres (656 feet) in radius.
