Liz, the correct termination is Up Line or Down Line, not Below!
Fond memory of browsing the museum at the Corris terminus. Dear old lady curator spoke to me, asking if I wanted to see the steam train go by. Thinking she was a little daft and that she was referring to another Corris train pulling into the station, I slowly ambled out on to the platform, just in time to miss a Castle headed excursion passing on the main line! Bugger!
