43035 pases Chilson on 25 August 2017 with the 1P21 07:10 Moreton-in-Marsh to Paddington GWR service. Luckily the fog was only obscuring the background, and not interfering with the sun where I was stood, although it looks like it was a good idea that I decided not to go to Ascott-under-Wychwood on this particular morning!
