Nope...
Seascale?

If it's not Wales I'll eat my hat. Til-phil and Bargoed being #2 and #3 (or #3 and #2) would certainly suggest that Pontypridd was #1. I would have assumed that it's an ATW 142 anyway, without even thinking about ATN.
N.B.: I don't have a hat.
Treherbert
I don't need a hat; I said I'd eat it if this station was not Welsh! My map suggests that it cannot be Treorchy because of the road layout, and that Ynyswen - though possible - is unlikely because where those houses are is a school.

Advice noted. Only it isn't in South Yorkshire.
