60063 runs along the down relief line at Denchworth on 7 May 2013 with the 6B33 13:00 Theale to Robeston Murco oil empties. Although the sun is very high in the sky during the middle part of the day during May, and consequently not the best quality of light, at least a day with nearly 100% blue sky meant no constant looking to see where the next cloud was coming from!
