43163 speeds past Uffington on 25 February 2016 with the 1A13 10:30 Bristol Temple Meads to Paddington GWR service. I had noted this going west a couple of hours earlier on the rear of the 1C05 08:00 Paddington to Bristol Temple Meads, and a quick check of the diagrams revealed it would return with this train. However, by this time the clouds that the Met Office had correctly predicted were building up rapidly. As I heard it approaching, I could see the fields both in the background, and to the north of the line going dark, as a large cloud enveloped the sun. Miraculously the light held just long enough to get this shot, and at least the clouds give the picture an impressive background.
