4th Nov: Colas Rail Plasser Theurer 08-16/4x4C 100-RT Tamper DR73919 working on 686T from Horsham Up T.C. to Dorking. 686T was routing Horsham-Crawley-Redhill-Dorking Deepdene/West-Guildford-Leatherhead and then Dorking (main). I guess there might be some engineering work at a section between Dorking and Horsham and could not pass through ? Seen here at Dorking West just only less than a mile away from Dorking (main) !
