Mass lineside trespass 1980s style! A4 4-6-2 4498 Sir Nigel Gresley speeds past Kingsey on 11 May 1986 with the Cambridge University Railway Club 1Z27 Cambridge to Banbury railtour. Even as late as the 1980s steam trains on the mainline would still result in families with children invading the lineside in a way that would bring out the BT Police now. This section of the Chiltern Line has now been redoubled.
