Goyaz 2-8-0 Locomotives in Brazil

Class Details by Steve Llanso of Sweat House Media

Class Francisco de Salies (Locobase 13342)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 39, pp. 259-262, Vol 66, pp. 276+ and 309+, and Vol 72, pp. 143+. Works numbers were 37079-37080 in October 1911, 37790-37791 in June 1912, 54408-54409 in January 1921, 54917-54918 in July, 58178-58179 in January 1925.

It's a little unusual for such a small Consolidation design to have such relatively tall drivers with as much cylinder volume as installed here, but the boiler was up to it as was the deep wood-burning firebox. A note on the second pair says that the name of the 9 would be Goncalves Barboza and Braz Abrantes for #10.

The two 1921 additions were essentially duplicates but put 5,500 lb (2,495 kg) more on the drivers. The resulting 82,500 lb (37,421 kg) raised the factor of adhesion to 4.10. Engine weight grew by 3 full tons, reaching 94,000 lb (43,638 kg). Tender capacity was 5 tons of coal or 2 1/2 cords of wood. The 1925 pair duplicated these figures.

Six months later, Baldwin delivered another pair that had the same power and heating surface dimensions, but split the difference in weights. Weight on the drivers was specified to be an even 80,000 lb (36,287 kg) and engine weight was confined only to 91,000 lb (41,277 kg). And the tender grew considerably in both fuel and water capacity.

At that point, rail weight was 46 lb/yard (23 kg/metre). Maximum grades were 2% and curve radii were as tight as 394 feet (120 metres).
