20312 approaches Lakenheath station with the 1Z61 09:10 Stowmarket to Trowse Rail Head Treatment Train on 27 November 2006, with 20307 bringing up the rear. There was considerable hooting before the train came into view, as the signalman hadn't closed the crossing gates and consequently the signals were at danger, in fact, the signal had only just been pulled off and the train was down to walking speed when I took this picture. It did mean however, that I then enjoyed some Class 20 thrash as they opened up through the station!
