London Underground
Greater London Council era

On 1 January 1970, responsibility for public transport within Greater London passed from central government to local government, in the form of the Greater London Council (GLC), and the London Transport Board was abolished. The London Transport brand continued to be used by the GLC.

On 28 February 1975, a southbound train on the Northern City Line failed to stop at its Moorgate terminus and crashed into the wall at the end of the tunnel, in the Moorgate tube crash. There were 43 deaths and 74 injuries, the greatest loss of life during peacetime on the London Underground. In 1976, the Northern City Line was taken over by British Rail and linked up with the main line railway at Finsbury Park, a transfer that had already been planned prior to the accident.

In 1979, another new tube, the Jubilee line, named in honour of the Silver Jubilee of Elizabeth II, took over the Stanmore branch from the Bakerloo line, linking it to a newly constructed line between Baker Street and Charing Cross stations. Under the control of the GLC, London Transport introduced a system of fare zones for buses and underground trains that cut the average fare in 1981. Fares increased following a legal challenge but the fare zones were retained, and in the mid-1980s the Travelcard and the Capitalcard were introduced.
