Something like a cross between HS1+2, Thameslink and Castlefield Corridor and Hauptbahnhof and Takt ...? London Great Central (LGC)?
A new station under Hyde Park (in place of car park?) with tunnels under eg Edgware Road, Oxford Street, Vauxhall Bridge Road, Brompton Road, Bayswater Road, with 'Tube-like' but Express (TPE/ TGV ish) services linking eg Cardiff, Bristol and Heathrow (Old Oak?), LGC- Sheffield-Leeds- Newcastle-Edinburgh- Glasgow; Southampton/ Ptsmth- Heathrow- LGC- Birmingham- Liverpool/ Manchester; and Dover (for the Continent)- LGC- Birmingham- Holyhead for Ireland.
What do you think?
