55020 (121020) approaches Little Kimble on 24 May 2010 with the 09:40 Aylesbury to Princes Risborough Chiltern Railways service. This picture was taken two days after the final slam door EMU trains ran on the national network, and proves there are still doors to be slammed! Just a couple of Pressed Steel 121s soldier on lightly loaded branch services. The unit is just crossing over a farm occupation underbridge, the wooden gateposts for which have provided a nest site for a pair of blue tits. Obviously the trains passing within a few feet of the nest did not worry them.
