43272 brings up the rear of the 1Q23 06:43 Bristol Kingsland Road to Derby RTC Network Rail test train at Chilson on 10 July 2025. 43357 was leading, slowing down prior to stopping near Ascott-under-Wychwood, as it was closely following the 1W02 11:52 Paddington to Hereford GWR train. I could see the stationary train in the valley as I drove home, but there wouldn't quite have been enough time to get to Ascott for another picture before it moved off.
