FC Argentine Great Western 2-6-4 Locomotives in Argentina


Class Details by Steve Llanso of Sweat House Media

Class 1 (Locobase 11228)

Data provided by diagram supplied at the [link] site, last accessed 17 April 2010.

This decade of German-built passenger tanks was very similar to the Serie 7 2-6-0s locomotives operated by the AGW at the same time. When the latter were superheated (Locobases 11218 and 11220), they were essentially identical to these 6-axle tanks except for their trailing tenders.

Locobase is not sure whether the Henschels were delivered with superheaters, but given the date, believes that to have been the case.


Class 9 (Locobase 11229)

Data from diagram supplied at the [link] site, last accessed 17 April 2010.

Just two years after North British delivered the last of the basic Serie 8 Prairie tank switchers, it produced 9 more switchers with bigger bunkers, larger cylinders, and taller drivers. Beyer, Peacock supplied 3 in 1910 (works numbers 5319-5321).

Although rated as switchers, these engines had dimensions that suited them for road-engine duties.
