I disagree. If you're both suggesting that the stadium is going to be on the side of Dyce near the station then Dyce will be gridlocked by those not taking the train, away fans etc... as there is no decent road infrastructure on that side of the airport. If the stadium goes on the airport side, nearer the link to the AWPR then that would be better for those travelling by car or bus, but it would be nowhere near the train station so nobody could get there by train.
Dyce doesn't make sense IMHO.
