Electric vehicles

The central power plant of the City of Stoke-on-Trent Electricity Department at Hanley was started up on 10th April 1913. This allowed a three-phase supply in bulk to the undertakings of Burslem, Hanley, Longton and Stoke. Demand was such that the plant was extended in 1919 and 1922. The Electricity Department operated a fleet of electric vehicles as seen in this view from c1920 outside the power house at Hanley.

I have no information about the vehicles and would welcome further details.
