20314 & 20107 make a terrific racket as they pull away from a crew change at Banbury on 1 July 2016 with the 7X10 02:16 Amersham to Derby Litchurch Lane, conveying London Underground S8 units for modifications. At 05:56 the sun is obviously extremely low in the sky, but it was only as the train pulled into the station that it actually appeared from behind the clouds, revealing that the foreground shadows were worse than I expected, which resulted in a swift lens change. 20905 & 20096 are on the rear of the train, hidden by Banbury's 1950s station building.
