Data from "The Demand for Railroad Equipment in South America and Other Countries", Railway and Locomotive Engineering, August 1919, p. 162; and "Goods Tank Locomotive-Central Argentine Railway",Robert Stephenson & Co catalogue (1922), last accessed in Flickr's Historical Railway Images 29 December 2024. Works numbers were 3606-3620 in 1912.
Data provided by Carlos Alberto Fern+ndez Priotti in Bryan Attewell ([] Steam Locomotive simulator program (April 2000).
These were used in freight and heavy switching duties.
Data from 1946 Beyer, Peacock catalogue hosted on Martyn Bane's website at [] (accessed 21 May 2006).
These were builders numbers 6304-6313 and were cross-compounds with Belpaire fireboxes. Carlos Alberto Fernandez Priotti in Bryan Attewell ([] Steam Locomotive simulator program (April 2000) notes that one of these was converted to a simple-expansion locomotive.
