70805 Challow 21 March 2016

70805 passes Challow on 21 March 2016 with the 6M50 07:55 Westbury to Bescot engineers train. Unfortunately this corresponded with the start of half an hour's worth of unforecast cloud. The sun was just disappearing as the train came into view, although had it passed at the correct time, rather than 19 minutes early, it would have been much darker!
