Data from "Six-Coupled Side Tank Enginer", Locomotive Magazine, Volume VI [6] (July 1901), p. 125. Works number was 911. Driver diameter is missing, so the figure given is an estimate.
Locobase bases his identification of the operator of this locomotive based on later buys by the ADR of Barclay tanks. The author repeats "Messrs Barclay" assertion that "The rigidity of framing is one of the features [they] believe in for tank engines, maintaining that all roads and conditions of running should be such as to allow of stiff framing to be used if possible."
An interesting point of view, given the preference in much of North American railroading for locomotives that could "work a bit" on indifferent track and still do the job.
