Class Details by Steve Llanso of Sweat House Media
Class 10 (Locobase 3729)
Data provided by Carlos Alberto Fern+ndez Priotti in Bryan Attewell ([
] Steam Locomotive simulator program (April 2000) and from Baldwin Locomotive Works Specification for Engines, as digitized by the DeGolyer Library of Southern Methodist University, Volume 20, p. 128. Works numbers were 14855-14856
Class 12 (Locobase 3730)
