Data from "Contractors' Tank Locomotive, Shanghai-Nanking Ry", The Locomotive Magazine, (15 June 1906), p. 101.
Sir J Wolfe Barry of Morrison & Barry had final say on the construction of these two saddle-tankers as his firm built the S N R.
The locomotive wasn't particularly big nor replete with innovation, but it didn't need more than it had to support construction work.
NB: Tube length is an estimate based on the calculation of tube surface area by subtracting reported firebox heating surface from reported total evaporative heating surface.
