EF de Cantagallo 0-6-2 Locomotives in Brazil

Class Details by Steve Llanso of Sweat House Media

Class 33 (Locobase 11838)

Data from Baldwin Locomotive Works Specification for Engines, 1888, as digitized by the DeGolyer Library of Southern Methodist University Voumel 12, p. 245. Works numbers were 7790, 7793, 7797 in February 1886.

This design as a relatively big radial tank, especially for the time, and was designed for 65-lb/yard (32.5 kg/m) rail. Given that these 0-6-2Ts were to share the track with a rack-system train, the specs writer inked in large capital letters: "EVERYTHING TO CLEAR CENTRAL RAIL." Baldwin's guarantee for was for this locomotive to haul 40 gross tons up an 8 1/2% grade while managing 40-m curve radii.

Locobase believes the locomotive was not a 2-6-0T (as shown in Connelly's Baldwin list) because of some special instructions in the specs. In recognition of the steep grades on this line, the specs had a special note about the trailing truck: "Guiding wheels on back [sic] of engine as near as pos. to the axle to guide Eng. aroung curves when required to descend backwards."

Note the relatively square (and relatively rare) cylinder dimensions.

At least one was rebuilt by the Leopoldina as an 0-6-0T after that large system took over the Cantagallo.
