The Edinburgh Airport Rail Link was scrapped because basically there was no money to do it – too much going on those wonderful Edinburgh Trams – which won’t actually now reach the airport apparently.
It is a pity, because the EARL project would have linked over 60 stations in Scotland to the airport. You would think that if Warsaw can manage to do it (driven by the European Football competition Poland is sharing with Ukraine), that we just might manage it in Scotland.
And do you know how close the actual railway is to the airport? It is this close, and this is not a zoomy picture. The next set of landing lights is on the other side of the train.
