EF de Canoe / EF de Cantagallo 2-6-0 Locomotives in Brazil


Class Details by Steve Llanso of Sweat House Media

Class 36 (Locobase 11839)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 12, p. 244.

Works numbers were 7777, 7780 in January 1886.

Rated for 90 tons up a 3% grade and around 40-m curves.


Class Jaguaribe (Locobase 12810)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 28, p. 62. Works number was 26256 in August 1905.

Rodrigues Faria & Company was the agent for this off-the-shelf metre-gauge Mogul delivered to its Brazilian client.


Class unknown (Locobase 11827)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 12, p. 75. Works numbers were 7376-7377 in July 1884

See Locobase 11578 for a description of this line. The specification for this pair of Moguls included the requirement to haul 80 tons of train up a 3% grade combined with curves of 40-m radius at 12 kph (7.5 mph). It was also required to achieve 30 kph (19 mph), presumably on the level. These were later converted to metre gauge when the Cantagallo was absorbed by the Leopoldina.
