66529 passes Uffington on 20 April 2021 with the late running 4Z47 10:30 Didcot to Barry Docks Dow Chemicals freightliner. I wouldn't normally be bother with such a backlit freightliner, but as this suddenly appeared on a short term plan while I was already at the location, and as it is not a train that I had photographed before, I accepted the less than ideal lighting.
