With Bledlow Great Wood visible in the background, 55020 (121020) accelerates away from Little Kimble on 21 March 2017 with the 2A06 07:20 Princes Risborough to Aylesbury Chiltern Railways service. With the prospect of these characterful bubble cars finally being withdrawn from the national network, I was keen to get some more pictures, so a forecast of a sunny morning was too good an opportunity to miss.
