Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 36, p. 164 and Volume 39, pp. 1 and 201. Works numbers were 35330 in October 1910, 37126 in October 1911, 37271 in November, and 52911 in January 1920.
Locobase is surprised by the substantial increase in the weight from an essentially identical pair of Consolidations built for the Virginia-Carolina in 1906 and 1908 (Locobase 12917). Perhaps the GS simply wanted more adhesion. Whatever the source of the increase, it constituted seven tons of additional weight on the drivers (almost 15%) and 7 1/2 tons gained in engine weight.
The GS apparently felt it had found a good design so it procured three more. Two came in the next year but the third didn't arrive for almost ten years.
