168216, 165003 & 165009 pass Oddington on 1 January 2023 with the 1T16 10:00 Marylebone to Oxford Parkway Chiltern Railways service. This unusual eight coach, three unit, combination seems to be a very extravagant provision for a Sunday morning, especially as it's New Year's Day. A revised timetable was in operation due to RMT industrial action, with just one train per hour, with no trains between Oxford Parkway and Oxford, and no trains leaving London after 16:05.
