I contacted Crosscountry and they are updating their service for Saturday on Wednesday but definitely no train between Birmingham and Cardiff, travelling from Aber we can get to Leicester via Brum but looks as if last train back is 17:18 so won’t get to station in time after game, unless we miss last 10 minutes or so of match . So Will have to travel back Leic>Derby>crewe>Shrew>Aberystwyth
