Perhaps a word could be had with HRH The Duke to see if the Duchy might be inclined to contribute to the financing of a "Nansleden Platform/Nansleden Road/Gorsaf Nansleden".
I think this has been discussed elsewhere, but Quintrell Downs station is about a mile away and given the short distance, there's little sense in adding an extra station between there and Newquay.
Of course what would really make a difference is trams - the airport alone gets 400k passengers/year and has 500 people working around it. If the Duchy could somehow kick that off, even with an electric bus "virtual tramway" - that would surely make a huge difference to the town.
