Tony, replying to your question about the railway in Swalcliffe seen from the 3A bus, this railway is my own private garden railway. The first track was laid 5 years ago and it is still being constructed. It uses a track gauge of 10 1/4" and is inspired by the "minimum gauge" railways of Sir Arthur Heywood. It is called The Barn Well Hill Railway, it is a private railway and does not open to the public or operate commercially though we welcome visitors by arrangement. We have a Facebook page, search for it by its name.
(BTW, it has nothing to do with the Swalcliffe Barn identified in another reply.)
