59204 passes Challow on 11 July 2018 with the diverted 7C77 12:40 Acton to Merehead Quarry Mendip Rail stone empties. Running 46 minutes late on an afternoon that was getting increasingly cloudy, but like everything else I photographed, passing in full sun! The sighting of this meant that I had seen half of the Class 59/2 sub-class at this location, in just over two hours.
