 The distinctive signal box overlooking Norwood Road and a similar signal box at the northern end of the station were demolished in 1956 and replaced by a single signal box adjacent to the north junction. The replacement signal box was in use from June 1956 until December 1981, when its functions were transferred to Victoria; the building still exists and is used by railway staff. The signalling at Herne Hill was upgraded from semaphores to colour lights on 8 March 1959 as part of the Kent Coast electrification plan.
