43003 Isambard Kingdom Brunel passes Aynho on Sunday 7 April 2013 with the diverted 1Z15 06:50 Paddington to Swansea First Great Western service. Due to engineering works at Reading, trains were travelling to the west via a reversal at Banbury. This train was running 32 minutes late, which was unfortunate, as at the booked time it was a fine sunny morning, with the remnants of the overnight frost in the field. However, high cloud soon appeared leading to very flat lighting, which persisted for most of the rest of the day.
