Data provided by Carlos Alberto Fern+ndez Priotti in Bryan Attewell ([] Steam Locomotive simulator program (April 2000).
Data from Vulcan Catalogue, ca. 1920 preserved at website [] (26 November 2004). See also "Compound Passenger Loco, Buenos Ayres [sic] Great Southern Ry," The Locomotive Magazine, Volume XII [12] (15 May 1906), pp.77-78; "Compound Locomotive for the Buenos Ayres [sic] & Rosario Ry", Volume 13 (15 July 1907), pp. 120-121; and "New Engines, Buenos Ayres Great Southern Ry," Locomotive Magazine, Volume 18 [XIII] (15 July 1912)
Very much the image of a British six-coupled of the same period, this two-cylinder compound design featured a Belpaire firebox, outside cylinders, and inside motion. Vulcan Foundry and Beyer, Peacock contributed engines to this class. See the LM report for a detailed description of the compounding system.
See Locobase 9924 for the superheated update of this class.
