Domingo Ramirez 2-4-0 Locomotives in Cuba


Class Details by Steve Llanso of Sweat House Media

Class 2 (Locobase 14359)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 54, pp.32+.

Locobase cannot identify the sugar central for which this six-wheeler was intended. The specs say that the curves would have a 100 foot (30.5 metre) radius (over 50 degrees) and used 40 lb/yard (20 kg/metre) rail, "same as on Central Lino Lines." On the sides of the tender, says another note, will be the following text:
