Goyaz 4-6-0 Locomotives in Brazil


Class Details by Steve Llanso of Sweat House Media

Class Felix Bulhoes (Locobase 13339)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 34, p. 379 and 39, p. 257. Works numbers were 34886 in June 1910, 34993 in July; and 35190-35191 in September.

These wood-burning Ten-wheelers were identical to 4-6-0s delivered to the Dourado and the Oeste de Minas within a year previous to the first quartet's arrival. These were followed a year later by 4 more. All had names:

Doutor Corumba 4

Senador Caiado 5

Amador Bueno 6

Francisco Salles 11

Wencesldu Braz 12

Bueno Brandao 13


Class unknown (Locobase 13340)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 49, p. 159 Works numbers were 41062-41064 in January 1914, 41169-41170 in February.

Almost four years after the first Baldwin Ten-wheelers arrived on the Goyaz (Locobase 13339), five more wood-burners with ever so slightly different firebox dimensions were produced to a new order. For some reason, Baldwin doesn't record the engine numbers and these locomotives had no names.
