Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 39, p. 263-264. Works number was 37398-37399 in December 1911.
The little tender behind this little Mogul held 65 bushels of coke. The 2's light construction was dictated by the 15 kg/metre (30 lb/yard) rail.
