43196 passes Baulking on 30 March 2015 with the 1A13 10:30 Bristol Temple Meads to Paddington First Great Western service. The bridge in the background, by the site of Uffington station, was at this time closed for work in connection with the Great Western Mainline electrification. Note the severe double incidence of ballast 'pumping', where water underneath the ballast causes the track to move under passing trains, pumping up dirty water that then gets spread along the line in the direction of travel.
