Two stations in Great Britain, about 85 miles apart, on the systems of different railway companies pre-nationalisation, and different BR regions after. They have borne the same (one-word) name; but did so simultaneously, for only three years. One of the two carried a different (two-word) name for 104 years, including an eleven-year closed interval followed by reopening -- ten years after which, it resumed the former one-word name; its counterpart of that name 85-odd miles away, having closed to all traffic 29 years previously.
Please identify, and indicate locations of, the two stations / names concerned.
Hint: the one with the chequered history, which has carried two different names, is in the flat-and-low-lands; the other is up in the hills.
