Very fast. And not just that. A big part of the cost and complexity of Crossrail isn't the tunnelling but rather the (re)builds of the stations, the remodelling and reconstruction of the above-ground street areas to increase capacity there too, and many other subtleties that people don't tend to think about.
It's the biggest civil engineering project in Europe, or so they say. And a big part of that is because you don't just massively increase transport capacity into the core of a major metro area. That would just overload all the other infrastructure.

The BBC's documentaries on the Crossrail are great at showing all of the complexity of building the thing and dealing with historic buildings, super-hard brickwork, archaeological discoveries, concert halls and more.
This seems pretty reasonable to me, to be honest. And most of it is done ahead of schedule isn't it?
How quickly do you think it should take from zero to a 21 km tunnel underneath London? It seems insanely fast now I think about it.
