Funilense 4-6-0 Locomotives in Brazil


Class Details by Steve Llanso of Sweat House Media

Class 4 (Locobase 13439)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 32, p. 75. See also Clodomiro Pereira, Railroads in the state of Spo Paulo (Secretaria da Agricultura, CommTrcio e Obras Publicas, 1903), p. 33. Works number was 33219 in February 1909.

This wood-burning Ten-wheeler went to a railroad that according to Pereira "...the object of the concession obtained by the Companhia C. A. Funilense was to develop the territory traversed by the road and create traffic." The result included "the precarious economic conditions of the Funilense road, which lies between the Mogyana road on the right and the Paulista on the left. It was constructed under great difficulties and would not have been completed except for two subsidies from the state government which were to be paid back after the road had been in operation 3 years."

Pereira explains: "The government was moved to this by the necessity of maintaining a settlement which existed at the farther end of the line."

Three more with Walschaert outside constant-lead radial valve gear were delivered in 1912; see Locobase 13440.


Class 5 (Locobase 13440)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 39, p. 229. See also Clodomiro Pereira, Railroads in the state of Spo Paulo (Secretaria da Agricultura, CommTrcio e Obras Publicas, 1903), p. 33. Works numbers 37509-37511 in February 1912.

Wood-burning Ten-wheeler that rolled along 14.9-kg/metre (30 lb/yard) rails up 2 1/2% grades and around 100-metre curves. Originally fitted with a Radley & Hunter balloon stack, but according to the specs "Hereafter ....R R Co. has extended smoke box 13" applied straight stack and netting to suit ...."
