Possibly the first visit of a Class 168 to the Cotswold Line? Chiltern Railways' recently converted hybrid battery/diesel 168329 passes Chilson on 20 June 2022 with the 5Q68 10:27 Aylesbury DMU Depot to Long Marston ECS. The unit was to be used on Honeybourne to Long Marston shuttles during the Rail Live event, although in the event the RMT rail strikes meant that it would only work on one day. This was running over 20 minutes late, due to the extreme late running of the previous passenger train.
