Data from "New Locomotive for the Powell Duffryn Steam Coal Company", The Locomotive Magazine, Vol VIII (14 March 1903), p. 184
At the time, PD were one of the largest suppliers of Welsh coal to ''the Metropolis" and this class of compact saddle-tankers supported a traffic demand that moved nearly three million tons per year.
Hudswell, Clarke's "workmanship and finish" was pronounced to be "of the best" and reflecting great credit on the Leeds builder, who made" a specialty of locomotives intended for such services as that mentioned above."
