New Niquero Sugar Company 2-4-2 Locomotives in Cuba

Class Details by Steve Llanso of Sweat House Media

Class 5 (Locobase 13630)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 54 p. 37. See also Cesar J Ayala, American sugar kingdom: the plantation economy of the Spanish Caribbean 1898-1934 (University of North Carolina Press, 1999). Works number was 41675 in September 1914.

Identical to a pair of locomotives delivered to Brazil almost 20 years earlier (Locobase 12166), the only real change in the 5 was an increase in boiler pressure. New Niquero was another of the Cuban American Sugar Company's many plantations. Ayala notes (p. 81) that it was a big estate, controlling about 67,000 acres of land (and 8,500 acres of colono cane) near Manzanillo in eastern Cuba. Its internal railroad system, on which the 5 served, led directly to its own seaport.

After the 1959 Revolucion and nationalization, the Nuevo Niquero would be renamed for Roberto Ramirez Delgado.
