We look at London's railways during the final decades of steam and provide you with a feast of nostalgia. At Paddington various classes are featured ranging from Collett's Kings to pannier tanks, including the 97xx type, which were fitted with condensing apparatus specifically for working freight traffic over city widened lines. A GWR diesel railcar journeys between Clapham Junction and Ealing Broadway, and part of the West London Line in the early 1950s. The line between Clapham Junction and Waterloo in the harsh winter of 1947, steam locomotives had to be used to rescue electric stock due to ice on the conductor rails. More action follows, included a Lord Nelson 4-6-0, and Bulleid's ungainly Q1s. We also see Bulleid's pacifics. Locomotives at Vauxhall, Nine Elms motive power depot, Clapham Junction, Wimbledon, Wandsworth Town, Barnes and New Cross, for a succession of trains in the 1950s. Maunsell's Schools 4-4-0s. Bulleid's double deck electric unit, long before it was repainted in blue. Steam in action around Wandsworth Road, Clapham, Brixton and Herne Hill. Here we see pacifics working the Golden Arrow and some of Maunsell's W class 2-6-4Ts, together with other types. Amongst these perhaps the most unusual is one of Fowler's condensing 2-6-2Ts. We visit the North London Line when ex-LNWR Oerlikon sets still worked the Watford and Richmond services also a railtour worked by gleaming Park 0-6-0T. The photographer was intent on recording the change of locomotives but fortunately, we also get a good view of the station building. For the centenary celebrations of the London Tilbury and Southend Railway, 4-4-2T No. 41966 assumed its old name of Thundersley. Also at Stratford, we witness some Thompson B1 4-6-0s. LNER express power is represented by a rare sequence of an A4 pacific in unlined wartime black at Marylebone. We also see the preserved A3 Flying Scotsman.
