Goyaz 0-4-4 Locomotives in Brazil


Class Details by Steve Llanso of Sweat House Media

Class Major Bulhoes (Locobase 13341)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 34, p. 377. Works numbers were 34822-34885 in June 1910.

The other one of these two wood-burning tanks was the Jose Jardin. For some reason, Baldwin didn't calculate the grate area, so Locobase used the firebox dimensions.
