Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 64, p. 223. 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 53107 in April 1920.
The Ingenio (later Central) Zaza was located at Placetas in the Remedios region of Santa Clara Province. Julian Zulueta, who Ayala describes as "one of the great barons of slavery in Cuban history" (in fn 11 on page 280, built the mill in the late 19th century, later connecting it through a railway with the north Cuban port of Caibarien.
As the sugar boom hit Cuba during and just after World War One, the CZ bought this plantation Consolidation to tackle the impressive 4 1/2% grades and curves with minimum radii of 75 metres (246 feet). See spec page 225 for the impressive list of tools that made up Baldwin's Schedule 71 and were described as "per Cuban Central Railway standard". The kit accompanied the 3's delivery.
Gene Connelly's Baldwin list doesn't record the later career of CZ's number 3. The mill was nationalized after the 1959 Revolucion and renamed for revered Mexican president Benito Juarez.
