FC Central Argentino 2-8-2 Locomotives in Argentina
Class Details by Steve Llanso of Sweat House Media
Class C7 C - saturated (Locobase 9497)
Data from "The Demand for Railroad Equipment in South America and Other Countries", Railway and Locomotive Engineering, August 1919, p. 162.
Class C7 CS (Locobase 3691)
Data provided by Carlos Alberto Fern+ndez Priotti in Bryan Attewell ([
] Steam Locomotive simulator program (April 2000). Works numbers were 3606-3620 in 1912.
These were used in freight and heavy switching duties.
Class CS8 (Locobase 3694)
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.
