London Electric Railway Company

The Underground Electric Railways Company of London Limited was a holding company made up of three separate companies, the Baker Street and Waterloo Railway; Charing Cross, Euston and Hampstead Railway and the Great Northern, Piccadilly and Brompton Railway. These railway companies founded sections of the Bakerloo Line, Northern Line and Piccadilly Line respectively. From 1908 they referred to themselves as the Underground Group andintroduced fare agreements. In 1910 the London Electric Railway Amalgamation Act was passed, merging these three companies into the London Electric Railway Company.

The London Electric Railway Company purchased the London General Omnibus Company in 1912, and also had joint ownership of the London and Suburban Traction Company which operated many tramways. In 1933 the Company was liquidated and nationalised, and services came under the control of the London Passenger Transport Board.
