The bright sunny morning of 29 November 2006 sees 20311 approaching Shippea Hill station with the 1Z61 09:10 Stowmarket to Trowse Rail Head Treatment Train, with 20310 on the rear. Needless to say I was glad the train was moving slowly as the 170 unit on the 09:57 Norwich to Liverpool service seen receding into the distance could very easily have blocked the view, as both trains came into view at the same time.
