Triple expansion pumping engine at Nottingham Corporation's Boughton Pumping Station. Built by Ashton Frost & Co. of Blackburn in 1907. This pair of engines were of unusual design having a horizontal HP cylinder and vertical IP and LP cylinders. They were sometimes called 'Manhattan' engines because engines of the same configuration drove the generators supplying the New York Subway in its earliest days. They pumped 3 million galls per day from 342 ft and had cylinders 25", 41" and 65" diameter controlled by Corliss valves. Stroke was 4 ft. Another photo of this engine appears in George Watkins' "The Steam Engine in Industry" Vol. 1. Photo donated by Michael Paul, previously Deputy Superintendent of Papplewick Pumping Station.
