Having read Phil's post and looked at the picture with the Class 66 Loco, I would rule out Frome because I have never known Frieghtliner locos to work Torr Works or Merehead Quarries... It's mainly
EWS▸ , Hanson, Yeomans & Mendip Rail locos that provide the traction for the workings.
However gramhame did point out that Corsham was relevant, So as he says, this is a tricky one!
Although nobody has worked out #9 in my Puzzle Edition 1
