Baturite


Class Details by Steve Llanso of Sweat House Media

Class 24 (Locobase 12085)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 31, p.207. Works numbers were 16392 in December 1898, 16441 in January 1899, and 32778 in March 1908.

Since the Baturite' bought 3 of these Consolidations over a 9-year span, they satisfied a particular need despite their diminuitive proportions. Even for the narrow gauge, the 24 had a small boiler and firebox. Wood-burning meant a larger than usual grate.

The Baturite' was later taken into the North East Railway of Brazil.
