Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 45, p. 208. Works number was 33958 in October 1909.
The S-A had only been incorporated in March 1909 and this Consolidation arrived very shortly afterward. Its remit was to scale the 3.4% grades and very tight 35-degree curves (equates to radii of 166 feet or 51 metres). A few months later, the S-A bought a very similar engine from the Moctezuma Copper Company; see Locobase 13231.
