A narrow gauge railway was proposed to ease the cost of supplying the Kempton engines. Construction had begun by May 1914 and by the end of 1915 the railway was ready to be opened.

Coal was brought to Hampton by barge, loaded into a large hopper by a high level crane, and then taken by the railway, in tipper wagons, to the pumping houses.
