Jim Connor takes us on a tour of four city lines including Broad Street station, Dalston Junction, Camden Road station on the North London line, Highbury, Silvertown station and Richmond. Two have closed, one is going to close and one is going through a great change. The widened lines are seen at Kings Cross, Farringdon, Moorgate, and Shoreditch. Film-makers capture the emptiness of Broad Street station, populated only by pigeons. With scenes in 1984, John Moss takes us on a cab ride, passing sprawling Dalston Junction and stopping at Camden Road. Tony Travis filmed the trains and stations of the North London line. The beautifully restored Camden Road station copes well with todays crowds, more than you could say about the 'garden shed' station at Highbury. North Woolwich starts in steam days, then a museum is established. DMUs enter service. Jim's tour passes old Blue (LNER) signs at the old Silvertown station and the tunnel beyond. 4472 makes a royal visit. Electric trains take over the service extended to Richmond. We feature the last day on 9th December 2006 and next day when a special appeared to close the line. The widened lines are seen at Kings Cross when N2s pound up the tunnels on each side of the station. Steam is also seen at Farringdon and Moorgate. The last days feature DMUs and specials on the route before it was taken over by suburban trains from Luton and Bedford. Thameslink trains ran until 9th December 2007 when the old station at Kings Cross closed and the new St Pancras International platforms opened. The East London line using Brunel's old Thames tunnel has always had a damp, dripping atmosphere. A good many train types ran on it during its life with the Underground, we see most of them. Shoreditch closes, then after a tour by 1938 tube stock the whole line closes for major refurbishment and upgrading.
