165003 & 165033 pass Brookfurlong Farm, Islip, on 2 January 2021 with the 1T19 09:20 Marylebone to Oxford Chiltern Railways service. With the prospect of some superb winter light (at least during the morning), and nothing else of interest in the locality, I decided to get some more pictures of Class 165s, which were monopolising the trains to Oxford, due to one of Chiltern Railway's periodic amended timetables, which sees Class 165s replace Class 168s.
