Funilense 2-6-2 Locomotives in Brazil

Class Details by Steve Llanso of Sweat House Media

Class 1 (Locobase 12987)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 29, p. 128. See also Clodomiro Pereira da Silva, Railroads in the state of Spo Paulo (Brazil). Spo Paulo (Brazil : State). Secretaria da Agricultura, CommTrcio e Obras Publicas, (Sao Paulo, Brazil, 1903). Works numbers were 28564, 28592 in July 1906

The Funilense was built on the 60-cm gauge between much larger railways -- Mogyana on the right and the Paulista on the left -- a location which Pereira da Silva in 1903 described as "precarious" and pointed out that its 41.2-km (25.6-mile) length between A. Negueira and Carlos Botolho generated gross receipts that were "...not sufficient to pay expenses of operation."
