In a 'money is no object' world, would there be merit in running HS2 through London to a south terminus rather that Euston? I can't see the benefit, but that could just be a Scottish view that 'London is London'.So, in my view, the crazy things about HS2 are that it goes to Euston rather than the south of the river and for example it goes to to the south of Manchester than the north. These are the places that could be "opened up" by faster services.
