Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Vol 60, pp. 142. Works numbers were 52710-52711 in December 1919.
This mining company's railway used 60 lb/yard (30 kg/metre) rails on a forgiving profile that included maximum grades of just 0.66% and curve radii of 400 meters (1,312 feet) or 4 1/2 degrees.
