[1] The corresponding connection (the Chislehurst Loops), allowing transfer of Charing Cross trains to/from the Chatham line was, opened on 19 June 1904.
[1] In the meantime, a new station had been opened at Petts Wood, ⅓ mile (0.5 km) south of Orpington Junction, on 9 July 1928.
[1] The last development of the junction under the administration of the Southern Railway came in 1941, when bomb damage to a wooden signal box required its replacement with an austere flat-roofed brick construction.
[2] Chislehurst Junction benefited in the form of the 1959 Kent Coast Electrification programme, which saw the Victoria-Chatham line quadrupled between Bickley and Swanley.
[2] This assumed the functions of the mechanical signal boxes at Bickley, Chislehurst and Petts Wood junctions on 31 May 1959.
[2] As part of the same project, work was undertaken to modify the junctions in order to increase the speed limit.
[2] The new Down Slow Bickley Loop shares the same alignment as the Up Chislehurst where they pass under the South Eastern Main Line.
