The London Underground tube station scenes were filmed on the disused Jubilee Line platforms, at the Charing Cross underground tube station. When all the new Jubilee line platforms opened on 1st May 1979, the newly combined station was given the replacement name of Charing Cross. All the Jubilee line services from Green Park, to the Jubilee line terminus station at Charing Cross, ended on 19th November 1999. However the Jubilee line platforms and the connecting track to/from Charing Cross are fully maintained by TfL for operational reasons, and a cross-over junction to the west of the platforms, enables trains to terminate and to start from both platforms. The new extension of the Jubilee line opened 20th November 1999, with the Jubilee line extended from Green Park, outwards via Westminster and Waterloo, terminating at Stratford.
