Argentine Transandine 2-8-4 Locomotives in Argentina
Class Details by Steve Llanso of Sweat House Media
Class unknown (Locobase 6378)
Data from Vulcan Foundry catalogue, ca. 1920 ([
]) and [], which gives the information that these three tanks were VF works #2398-2400.
Obviously meant to spread out a useful amount of adhesive weight over a long wheelbase, these locomotives had long relatively thin side tanks.
