FC Rosario a Puerto Belgrano 4-4-0 Locomotives in Argentina
Class Details by Steve Llanso of Sweat House Media
Class 21 (Locobase 3738)
Data provided by Carlos Alberto Fernandez Priotti in Bryan Attewell ([
] Steam Locomotive simulator program (April 2000). See also the builder's photo "Rosario Railway, Argentine" on Flickr's "Historical Railway Images" photostream at [], last accessed 27 April 2024. Works numbers 4117-4129 in 1908.
Fernandez says these engines were based on the Outrances that ran on the Nord in France.Their place in Argentine rail history is secured by the fact that they introduced the use of the Schmidt superheater.
