Norte Guatemala 4-6-0 Locomotives in Guatemala


Class Details by Steve Llanso of Sweat House Media

Class Rufino Barrios (Locobase 12100)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 19, p. 75 Works number was 13966 in March 1894.

Specifications included the ability to scale 2% grades and get around 14-degree (82-metre/269-ft) curves. Rufino Barrios retained its road number as its railroad transformed into the Guatemala Railway in 1903, then into International Railway of Central America in 1913. It was finally condemned in 1939.
