Having just reversed at Basingstoke, Network Rail MPVs DR98965 & DR98915 pass Potbridge on 11 November 2016 with 3S86 05:23 Effingham Junction to Effingham Junction Rail Head Treatment Train. This had previously visited Wimbledon, Shepperton, Kingston, Twickenham, Windsor and Staines. My main reason for visiting this location was to get a picture of 47812 hauling a Class 442 unit from Eastleigh to Ely. However, shortly after taking this picture, the train was reported as cancelled, so it was a 100 mile round trip for a MPV RHTT picture!
