Data from "The Government Railways of North China, the Pekin-Mukden Ry", Locomotive Magazine, Volume XXII [22] (15 August 1916), p. 165.
This mixed-traffic Mogul had a sloping grate which caused the builder to set the rear axle 2 1/4 ft (686 mm) further away from the second axle than the second was from the first. A straight boiler led back to a slightly bigger firebox. Outside cylinders were fed by inside valves.
