1883 The company's installation of electric lighting at the Notting Hill Gate, Edgware Road and Aldgate stations of the Metropolitan Railway was powered by a steam-powered Siemens generator at Edgware Road Station; the generator developed alternating current that was fed to the other stations through a transformer and along cables run through the tunnel to transformers at the other stations.[1].
1884 John Dixon Gibbs was a director of the National Company for the Distribution of Electricity by Secondary Generators.[2]; presumably Lucien Gaulard was another.
