FC de Sagua la Grande 2-6-0 Locomotives in Cuba

Class Details by Steve Llanso of Sweat House Media

Class 16 (Locobase 11572)

Data from Baldwin Locomotive Works Specification for Engines, 1888, as digitized by the DeGolyer Library of Southern Methodist University Vol 15, p. 9. Works numbers were 9800-9801 in February 1889.

What did the RF&P, a small railroad in Alabama, and a sugar road have in common? Well, a look at Locobases 11570-11572 show at least two shared qualities: The engines were built nearly seriatum in Philadelphia in 1889 and they all used the same grate. Firebox areas differed a little and the boiler more so, but all were 6-drivered freight engines.

The two Moguls shown in this entry went to a sugar-tobacco road of moderate size (137 km/85 miles, 70,000 tons of sugar, 2,100 tons of tobacco, and 230,000 passengers) in western Cuba.
