Just ahead of an approaching storm, C811 (51801 & 51519) approaches Purton (between Kemble and Swindon) with the 10:30 Cheltenham to Swindon service on 20 July 1985. This unit was withdrawn in 1989 and cut up at Mayer Newman at Snailwell the following year. In common with a lot of Western Region units it had already lost its intermediate trailer (59548) by the mid 1980s.
