We need to build more, but at the moment the UK has some of the highest infrastructure costs in the world.

Britain overpays for transport infrastructure. On a per-mile basis, HS2 is the world’s most expensive railway under construction costing more than twice as similar projects elsewhere. Madrid was able to build an entire metro-system for £4bn, it cost us £18bn to build Crossrail – more than ten times more on a per mile basis.
