165033 & 168323 pass Charlton-on-Otmoor on 24 May 2023 with the 1T52 17:45 Marylebone to Oxford Chiltern Railways service. Until recently I had only seen a handful of trains worked by Class 165s and 168s in multiple, but now the practice seems to be much more common. Presumably the Class 165's top speed of 75mph, as opposed to the Class 168's 100 mph was the reason they weren't formerly used together. Note the two rabbits enjoying the evening sunshine next to the road on the left.
