During 1974/75, the first section of the control panel in London Bridge ASC was commissioned, gradually replacing redundant signalling locations in the area and principally replacing the old 1923-built London Bridge signal box. Railway track layouts were altered to separate Cannon Street, Charing Cross and London Bridge (Central) traffic. Prior to the London Bridge ASC, Cannon Street and Charing Cross traffic arrived at London Bridge on all lines and was either signalled approaching or leaving London Bridge station to their respective destinations. With the development of London Bridge ASC, all this traffic was sorted out further outside London Bridge, mainly at Parks Bridge but occasionally in the New Cross area. The London Bridge central traffic was kept as a separate working railway from the eastern side.
