jfc. Even if you allocate cost of all of Crossrail's 120km route to the 21km central tunnels it only works out as £0.7bn/km

And that's heavy rail which is innately more expensive (tunnels are 6.2m dia vs 3.8m for london underground deep level tube)
-
uh what "The line's tunnels will largely consist of twin tunnels with diameters of up to 23.5 feet (7.2 m)."

why are new york *subway* tunnels bigger than uk heavy rail tunnels?
