Data from "Tank Locomotive for the Indian Public Works Department", Locomotive Magazine, Volume XXI [21] (15 December 1915), p. 266.
LM's report says nothing about its intended work environment, but the narrow gauge and small dimensions, as well as the owner, suggest an industrial setting. The heavy plate frame hid most of the valve gear's components, even though both the cylinders and valves were outside. The pistons drove the rear axle. The tall steam dome sat precisely over the middle axle and the side tanks extended from firebox to smokebox. A tall capped stack and open cab with canopy top completed the picture.
