Class Details by Steve Llanso of Sweat House Media

Class 7 (Locobase 3732)

Data provided by Carlos Alberto Fern+ndez Priotti in Bryan Attewell ([] Steam Locomotive simulator program (April 2000).

The balanced arrangement and relatively high drivers show that this design was intended for two-way passenger traffic out of Buenos Aires.
