66952 passes Uffington on 4 June 2021 with the late running 4L36 07:39 Wentloog to Felixstowe North freightliner. I had gone here specifically to photograph the 5Q11 07:51 Maidenhead to Swindon, and 5Q12 09:49 Swindon to Maidenhead Class 769 EMU test runs. I had made sure that 5Q11 had actually left before I set off, but when I got to Uffington, I discovered that after running 52 minutes late, it was terminated at Reading. Rather than go home without taking a picture, I therefore waited for yet another picture of 4L36, albeit this time from a different angle.
