Dramatic lighting at Princes Risborough on 19 May 2017, as 55034 (121034) & 55020 (121020) start their journey along the single track line to Aylesbury with the 2A50 18:06 Princes Risborough to Aylesbury Chiltern Railways service. This was on the final day of Class 121 operation with Chiltern Railways, which explains the use of both of their units. Throughout the day 55034's destination blind had been turned to various comedy locations. It would be a very long journey from here to Machynlleth!
