Having lived in the area, I would say that Radstock is rather more turned towards Bath, as is Frome. Few people are likely to want to travel between Frome and Radstock or v.v. If you could squeeze a station in behind the Cheese & Grain it would be more convenient for Frome town centre than the existing station, but what then? Do you exist on a train shuttling backwards and forwards or do you go on to Westbury and hope there will be hordes of people who will want to change there for onward destinations? This does sound like an idea on the lines of, “Here’s a line that doesn’t need too much work if we want to rebuild it: let’s rebuild it.”
