Class Details by Steve Llanso of Sweat House Media

Class A S HARRIS (Locobase 10015)

Data from the website celebrating the activities of Colonel Hollman Fred Stephens and in particular the PD & SWJR -- [link], last accessed 26 March 2009.

This side tank (works 2697) was the third locomotive delivered to the PD & SWJ in 1907. Like the radial tanks (Locobase 10014), the Harris was given an L & SW number, but only had it applied when the Southern Railway took over the former in 1923. From then on, 756 worked switching (shunting) duties and occasional turns as a pilot engine until its retirement and scrapping in late 1951.
