800001 & 800002 pass Challow on 6 April 2017 with the 5X31 10:17 Swindon to Reading West Junction test run. A pity the 'Inspiration Delivered' red logo covered 800002 was not leading, but it can be seen underneath the road bridge. However, the white livery of 800001 certainly shows up well in the early morning sunshine. Sunshine was certainly not predicted by the Met Office!
