Klas Irmaos & Cia 2-8-2 Locomotives in Brazil


Class Details by Steve Llanso of Sweat House Media

Class 332 (Locobase 15400)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University,Vol 78, pp. 262+. Works number was 58548 in July 1925.

See Locobase 15397 for a description of this design. These and several others shown in Locobse 15396 were built as parts of a large order of locomotives for the Sao Paulo Rio Grande.

The 332 was produced as part of a stock order for Baldwin Brazil. It was ticketed for the Siqueira & Company, but diverted to . Numbered in the SPRG sequence, it would soon join that railway's roster. Three others went to Argentina's Cordoba railway; see Locobase
