Uniao Dos Refinadores 0-4-2 Locomotives in Brazil


Class Details by Steve Llanso of Sweat House Media

Class Monte Alegre (Locobase 13986)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 44, pp. p. 184. Works number was 39191 in January 1913.

Unlike many of the other narrow-gauge engines that traveled from Baldwin to Brazil, this engine did not serve the sugar industry. Instead, it operated on a coffee plantation.
