 On 15 May 1903 the first electrified section from Westminster to Tooting was opened by The Prince and Princess of Wales who rode the route in a specially decorated tramcar, and paid their fares with halfpenny coins minted for the occasion.The last horse tram ran on 30 April 1915.Much of the system used a conduit system of electric current, as the metropolitan boroughs had the power of veto on the installation of overhead wires.
