This tiny little saddle tank seems to have been the first locomotive to operate on this Yorkshire quarry railway. L. G. Charlton says this was believed to be works number 1446. In service, it was credited with a trailing load of 12 to 14 tons. It was withdrawn in 1920 in favor of a gasoline-powered Whitcomb engine.
So small was the engine that when it was offered to the Festinog Railway in October 1924, the latter declined because it saw no need for such a peanut.
