A Look at HS2's Old Oak Common Station

Most expensive TGV route so far €15m/km. ~200km London-Birmingham. Therefore ~€3bn for the high speed line itself. €5bn each end for stations? €10bn for tunnels into London? The rest spent on typical British dicking around with procurement, only people worse at wasting money on getting stuff done is the US. I wonder if it’s to do with the way we contract things? Edit: another stat says €20m/km LGV Mediterranean.

There's a lot of tunneling on HS2 - including massive underground stations at Euston and OOC, a new station in Birmingham, and tunnelling in London and Chilterns.

That has to happen whether the trains run at 180mph or 80mph.

LGV Mediterranean has to negotiate the hilly terrain in southern France. Plenty of tunnels and viaducts. €20m/km. Way less than us. The problem is with how we manage construction projects in the UK.

It's hard to compare, the UK is more densely populated, twice as high as France. My guess is a lot went into buying off property owners.

They budgeted £1.1b, but have already spent £2b

You'd be amazed just how poorly dynamite works for making miles of tunnel, in between up to 12 layers of pre-existing tunnels, through wet central London clay.
