Is the comparison with international projects after taking into account the higher population density and resultant higher land values and greater need for tunnelling in the UK?
It is now comparable or greater on a per route-km basis than a base tunnel project......
EDIT:
The current HS2 requirement can be met with about 500 route km of tunnels.
At the route-km figure of the Ceneri Base Tunnel that is £61bn
At the turn out cost of the Gotthard Base Tunnel we would be looking at £66bn
At the projected cost of the Koralm Base Tunnel we would be looking at ~£77bn
Whilst at the projected final cost of the Semmering Base Tunnel we would be looking at only ~£50bn
Whilst stations cost a lot of money..... they don't cost £40bn.
Considering the station now only has.... eight, and only five in a city centre?
