LCC , London County Council x London County Council

The Council inherited from the Metropolitan Board of Works the power under the Tramways Act, 1870 (which the Board had not in fact exercised) to construct tramways and lease them to operating companies and also to purchase at prescribed future dates the undertakings of the existing tramway companies (of which there were fourteen in 1889). Until the passing of the London County Tramways Act, 1896, the Council's powers did not extend to operating a tramway undertaking itself. The London Street Tramways Company's undertaking was the first to be purchased and released on a short-term basis in 1892 and the arbitration proceedings which ensued set the pattern for subsequent purchases.

When the undertaking of another of the companies, the London Tramways Company, which operated wholly South of the Thames, was purchased with effect from 1 January 1899, the Council decided to operate the system itself, appointing a General Manager of Tramways as the head of a new Department for this purpose and the direct management of other systems followed, as they were purchased or leases expired. Electrification powers were conferred by the London County Tramways (Electrical Power) Act 1900 and the first section of electrified line (running between Westminster Bridge and Tooting) was opened by the Prince of Wales of 15 May 1903. Electrification was completed by 1912, the large generating station at Greenwich being opened in two stages in 1906 and 1910.

The attempt of the Council to continue to operate the horse omnibus service between the south side of Westminster Bridge and Charing Cross which had been maintained by the London Tramways Company was frustrated by litigation and it was not until 1906 after much controversy that Parliament sanctioned the carrying of tramways over Westminster and other Thames bridges and along the Victoria Embankment. The Kingsway subway, designed to link the northern and southern systems was opened between Holborn and Aldwych in 1906 and extended to the Victoria Embankment in 1908.

The question of the financing of the undertaking and the form of accounts was the subject of considerable controversy at the 1907 L.C.C. elections which resulted in a change of party in the majority in the Council Chamber.

Under the London Passenger Transport Act 1933, the Council's tramway undertaking, the undertakings of the omnibus companies and the underground railways were transferred to the newly-created London Passenger Transport Board with effect from 1 July 1933.
