Rio Grande do Sul 2-8-0 Locomotives in Brazil


Class Details by Steve Llanso of Sweat House Media

Class 264 (Locobase 12919)

Data from Baldwin Locomotive Works Specification for Engines, 1903, as digitized by the DeGolyer Library of Southern Methodist University Volume 28, p. 237. works numbers were 27409-27413 in February 1906.

NB: see Locobase 13987 for an overview of the RG do Sul as described by Lionel Wiener in 1912.


Class 301 (Locobase 10640)

Data from "The Locomotive Works of A Borsig, Tegel", The Locomotive Magazine, Vol XIV (15 February 1908), p. 29-31. See also Lionel Wiener, "Locomotives of the Rio Grande do Sul", Volume 19 (14 June 1913), p. 150-151; and Lionel Wiener, Les chemins de fer du Breñsil (Paris: H. Dunod et E Pinat, Editeurs, 1912), p. 121.(Thanks to Teemu Koivumaki whose 2023 email included a comprehensive spreadsheet of Brazilian steam locomotive builders, works numbers, and owners.) Works numbers were 6269-6274 in May 1907,6275-6276 in June, 6547-6551 in January 1908, 6552-6557 in February, 6558 in March, 6575-6577 in March 1909, 6578-6583 in April, 6584-6588 in May, and 7381 in December 1910.

Jens Merte's Borig production compilation gives the full French name of the RG do Sul as "Cie Auxiliaire de Chemins de Fer au Bresil, Brüssel, für Rio Grande do Sul, Brasilien"

Consolidations made up the bulk of the 67-locomotive order from Borsig in 1906, which is described in Locobase 20225. Wiener offered an extended discussion of the reason for the relatively large heating surface area in these engines. After noting that the original intent was to use them "on lines where it might necessary or advisable to be able to develop extra power during a short time." But actual service use required such "extra power" for longer periods.

But, Wiener continued, a locomotive's tonnage rating is limited either by steaming capacity or adhesion weight. One could reduce steam demand by relining the cylinders, reducing volume, or increase adhesion weight. The RGdeS chose the second option by installing placing five tons (short, long, or metric, Wiener doesn't say) on the drivers.

He criticized the Consolidation for too long a rigid wheelbase. "It had originally been intended to build the fourth axle on the Golsdorf system, which would have been getter ...There's too much strain on the existing wheelbase, and in consquence too much wear and tear."

Class 335 (Locobase 20855)

Data from "The Locomotive Works of A Borsig, Tegel", The Locomotive Magazine, Vol XIV (15 February 1908), p. 29-31.

Class unknown (Locobase 20856)

Data from Lionel Wiener, Les chemins de fer du Breñsil (Paris: H. Dunod et E Pinat, Editeurs, 1912), pp. 118-121.

These Ten-wheelers were the last of the 67-engine order from Borsig delivered to the Rio Grande do Sul. They came in two versions (saturated boiler shown here and superheated in Locobase 20857) both using Borsig patent Hochwald piston valves. A boiler identical to earlier Borsig is described as having "exceptional power/puissance exceptionelle"
