Cardiff Central and Grangetown (The former is a little run down but the second is very uninviting)
Barmouth and Llanaber (The latter is desolate and everything is rusty from the storm a few years ago. Lovely views if you are looking the other way though!)
St Erth and Lelant Saltings (Lovely location but the station has zero character)
Shrewsbury and Welshpool (The latter has lost more or less all of its facilities since the track was re-aligned years ago)
Abergavenny and Pontypool and New Inn (The only good thing about the latter is that it'd make a great setting for a zombie apocalypse)
Bridgend and Wildmill
Bath Spa and Oldfield Park (Despite having over 300,000 entries and exits, the station has absolutely nothing. Except a help point and a bus shelter)
And as previously mentioned by another user... Bristol Temple Meads and Bedminster, where the best thing would probably be to flatten the latter and start again.
