Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 66, pp. 300+. Works numbers were 56124-56125 in January 1923.
The heating surface area in the boilers of these wood-burning Consolidations seems small compared to the just previously delivered Ten-wheelers shown in Locobase 15138. They were certainly meant for longer, heavier trains, but were constrained by the same axle loading considerations as the 4-6-0s.
