Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 64, p. 207. Works number was 54011 in November 1920.
The Central Ulacia was located in Santa Clara Province. It was named for the brothers who built the mill in 1913-1914 on their own land near Rodrigo and between Santo Domingo and Sagua. They were probably familar with this oil-burning plantation Consolidation design.
The 3 was later sold to the Central Andrieta. After the 1959 Revolucion and nationalization, the 3 was renumbered 1345 and the CA was renamed Mal Tiempo.

This oil-burning plantation Consolidation used 11" (279 mm) piston valves to supply steam to the cylinders. It was sold to the Cuban American Sugar Company, which soon moved it from its CU railway in Santa Clara Province to the Central Tinguaro in Matanzas.
