55034 (121034) & 55020 (121020) approach Monks Risborough 19 May 2017 with the 2A46 17:00 Princes Risborough to Aylesbury Chiltern Railways service. This was on the final day of Class 121 operation on the line, which explains the highly unusual use of both of Chiltern's single car units. The displayed destination seems a bit optimistic!
