Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 54, pp. 127+. Works numbers were 42931 in February 1916 and 43723 in July.
Originally ordered to be produced as stock in December 1914, the 7 was a duplicate of the Panama Railroad's Mogul design (of which 40 were produced in 1907 and are described in Locobase 12183) was taken off the shelf in early 1916 and sold to Agramonte, Cuba-based CU. Although a sugar road, the CU also operated freight service for which this 2-6-0 was a handy size. The 8 joined the 7 five months later. At the time of their delivery, these were the two biggest Baldwin Moguls in Cuba.Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 64, pp. 209. Works numbers were 54069 in November 1920.
Unlike the two earlier Baldwin plantation Moguls shown in Locobase 14404, this oil-burning 2-6-0 was of moderate size and power. The CU was based at San Luis in Oriente Province. When it was nationalized after the 1959 Revolucion, the central was renamed for Rafael Reyes and the 3 renumbered 1581.
