Data from "Railway Noters-Kowloon-Canton Ry.," The Locomotive, Volume 16, No 220 (15 December 1910), p. 259. See also Railway & Locomotive Engineering, Vol XXV (April 1911), pp. 142-143.
This was a big, sturdy tank engine with a short Belpaire boiler, water tanks on both sides from the middle driver set to the cab (these held 1,960 Imp gallons/2,352 US gal) and a bunker tank over the trailing bogie that held 540 Imp gal (648 US gal).
