70805 passes Challow on 28 November 2017 with the 6M50 07:55 Westbury to Bescot engineers train. This short train is the ideal length to fit between the masts at this location! I was extremely lucky with the sun here, as the foreground was still in cloud when I saw it appear in the distance, and the sun only finally came out from behind the cloud just as it passed underneath the bridge!
