43251 passes a fine selection of autumn colours at Radley on 16 November 2021, as it heads south with the 1Z01 09:38 Derby RTC to Exeter Riverside Network Rail test train. 43272 was bringing up the rear. This is the plain line pattern recognition train, which includes overhead line inspection coach 975091 Mentor. Not much use here for that at the moment, as the electfrication between Didcot and Oxford has been temporarily abandoned.
