Burma Railways locomotive diagrams posted on Flicker by Florian Grupp, last accessed 3 March 2012.
Data from "Oil-burning Tank Engine for the Burma Railways," The Locomotive & Railway Carriage & Wagon Review, Volume IV (15 October 1899), p. 154; and Nielson diagram No 1429. Boiler pressure is an estimate.
Small tank with a small footprint. In addition to the oil in the tank, which was burned using the Holden System, the bunker held 8 cwt (896 lb) of coal.
