Carmen Central 0-4-2 Locomotives in USA-Puerto_Rico


Class Details by Steve Llanso of Sweat House Media

Class 1 (Locobase 13756)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 36, p. 230. Works number was 35601 in October 1910.

Like the Central Sucroise Coloso engine delivered in 1906 (Locobase 12951), this was a tiny tank operating on a Puerto Rico sugar plantation over about as narrow a gauge as one might adopt outside of a live-steam event. Curves were as tight as 110 ft radius (33.5 m).
