Just over two weeks after 165030 travelled north over the Cotswold Line, en-route for rectification work at Long Marston, the Chiltern Railways interloper headed back south on 4 August 2020, running as the 11:40 Long Marston to Aylesbury DMU Depot ECS. It is pictured here passing Cornbury Park, just to the south of Charlbury. The start of the double track section of the Cotswold Line can be seen behind the train, and the tower of Charlbury's church can just be seen poking above the treetops in the background.
