Central Constancia Sugar 0-4-2 Locomotives in USA-Puerto_Rico


Class Details by Steve Llanso of Sweat House Media

Class Jesus Maria (Locobase 11758)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 9, p. 163. Works numbers were 4750 in July 1879.

This little tank was sold to Maitland, Phelps and Gene Connelly's tabulation of Baldwin records express expresses uncertainty about its destination. His guess that it was Constancia Sugar Company in Puerto Rico correlates well with the specs.
