Cowans Sheldon twin jib cranes DRC78235 & DRC78266 bring up the rear of the 6M50 07:55 Westbury to Bescot departmental working on 16 September 2013. The two highly colourful Colas track machines are pictured passing Bourton. The train was being worked by 66161. I had photographed the same two cranes, on the same working, earlier in the year, although on that occasion they were at the front, rather than the rear of the train.
