It certainly had direct trains from Paddington a few years ago. I remember getting off an HST there, having travelled from Reading to go walking on the Malverns. No one else got on or off, so even though it wasn't a request stop, it still felt as if the HST had stopped just for me . Quite a contrast with Reading!Does Colwall still have trains to both Birmingham and Paddington? It used to I think.
Freshford, Avoncliff, Dilton Marsh, Thornford and Yetminster offer similar contrasts to Bristol Temple Meads
