66850 David Maidment OBE passes Challow with the lengthy 6M50 07:55 Westbury to Bescot on 2 January 2014. It has just moved across onto the up relief line, and will wait at Wantage Road, while the 1A10 09:00 Bristol Temple Meads to Paddington First Great Western HST overtakes it. The bridge in the background is living on borrowed time, as the forthcoming Great Western Mainline electrification will see its demolition.
