Hello to You all, I'm new here too.
You have not mentioned from where you intend to run the train from, or approximately when. It is possible I may be interested in the trip if it doesn't collide with all my other commitments
I knew Ludgershall very well till 1971 and would Love a revisit, though google earth shows there's not much left of what I knew..
For those interested in the line there I would recommend
