AOG, a bit odd, at first glance,that it's not going to St Pancras but St Pancras is one stop on the tube from Euston , or a very short cab ride. But you can imagine, if there's fuss about it going to Euston, how much more,and how much more cost, there would be if it was being built demolishing all the buildings and crossing roads that lie on that alternative route.
Am reminded what the boss of SNCF said,when he was told that we had difficulty building a high speed line from the Channel Tunnel because of local objections: " In France,if we need to drain a swamp, we don't ask permission of the frogs first" [Sounds better in English where 'frogs' is insulting to French people ]
