165017 & 168005 pass Tackley on 20 March 2021 with the 5U17 11:17 Oxford to Banbury Depot Chiltern Railways ECS. This was running 22 minutes early, passing me 10 minutes before its departure time! The few Chiltern Railways trains on the Cherwell Valley route usually operate during the hours of darkness, so this VSTP (Very Short Term Planning) working was worth recording.
