Barra Bonita-Rio do Peixe 4-6-0 Locomotives in Brazil

Class Details by Steve Llanso of Sweat House Media

Class T1 (Locobase 15138)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 66, pp. 298+. See also the Centro-Oeste website's description of this railway at [] number was 55351 in April 1922.

This design was an exact duplicate of two Noroeste locomotives delivered in 1910 by Baldwin (Locobase 13293). The only difference in this wood-burning Ten-wheeler was a short ton more in adhesive weight.

The BB-RdP was part of the RVPSC (Rede de Viatpo Paraná - Santa Catarina), organized in the 1930s to merge serveral railways including the Estrada de Ferro Paraná, Estrada de Ferro Norte do Paraná, ItararT-Uruguai, Ramal de Spo Francisco, and Paranapanema. The Barra Bonita had three locomotives in 1936--this Baldwin and two similar Ten-wheelers from Hanomag (works numbers 6533 in 1921 and 6856 in 1922 and later renumbered 340-341).
