Norte do Parana 2-6-0 Locomotives in Brazil


Class Details by Steve Llanso of Sweat House Media

Class 1 (Locobase 13146)

Data from Baldwin Locomotive Works Specification for Engines, as digitized by the DeGolyer Library of Southern Methodist University, Volume 30, p. 244. (Many thanks to Emmanuel Fernandez da Silva for his 12 August 2021 email asking about the works numbers for this class and for providing information about the #1's preservation.) Works numbers were 31091-31092 in June 1907.

These were both sold to Monsieur Gaston. de Cerjat on behalf of the E de F de Nord du Parana, a southestern Brazilian road owned by French interests. It was a short line that only amounted to 27 miles (43.5 km) by 1915. By this time it was part of the larger Brazil Railway Company.

Emmanuel Fernandez da Silva notified Wes Barris and me to tell us the buyer was "Monsieur Cerjat (his real name was Gaston de Cerjat) in 1907." da Silva added: "[T]his locomotive is actually still standing, well, at least as a museum exibition in the "Museu do Contestado" in Catador, estate of Santa Catarina, in southern Brazil."
