Matanzas 2-6-0 Locomotives in Cuba

Class Details by Steve Llanso of Sweat House Media

Class 29 (Locobase 12041)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 18, p.54. Works numbers were 12891-12892, 12948, 12953 in September 1892. See also Oscar Zanetti Lecuona, Alejandro Garcfa Alvarez, Sugar & railroads: a Cuban history, 1837-1959 (U of North Carolina Press, 1998 (translation)), pp. 236, et seq.

The Matanzas ran along the North Coast of Cuba north of Havana. Operating in a lush sugar-growing region, the railroad also cooperated with the sugar companies "in an optimal way" like nowhere else in Cuba, according to Zanetti and Garcia. Run by Tirson Mesa, the only Cuban to head up a Cuban railroad, the lines were well-built on a gentle profile.

These relatively large Moguls might be seen to reflect the prosperity of the Matanzas in the decade preceding the Cuban Revolution that accompanied the Spanish-American War.
