EF de Cantagallo 4-4-0 Locomotives in Brazil


Class Details by Steve Llanso of Sweat House Media

Class Juturnahyba (Locobase 11578)

Data from Baldwin Locomotive Works Specification for Engines, 1888, as digitized by the DeGolyer Library of Southern Methodist University Vol 15, p. 16.

Works numbers were 9832-9833 in February 1889.

The Cantagallo was a mountain railway using the Fell System of a raised center rail to assist traction when it opened in 1873. By the mid-1880s, however, this oddly gauged line used the Fell System of shoes for downhill braking only and the company began buying Baldwin locomotives.

The last pair to arrive was this brace of Eight-wheelers (the other named Macahe) that are described as being convertible to metre gauge. The specs also show that the tender's tank was to be lettered "E de F Leopoldina"on one line, "Ramal de Macahe" on the second. ("Ramal" means branch.) When the Leopoldina took over the Cantagallo for good in 1911, it renumbered these little engines 83 and 84.
