Jim Chisholm remarked:
Eight boring machines have been cutting their way through earth to
create 26 miles (42km) of tunnels."

That's the new tunnels, plus the exciting machines which re-did the
kilometre of Connaught tunnel.
And isn't it a shame that these boring machines and their expert
workforce cannot now move directly to start CROSSRAIL2?

Not really, much of them will be worn out, and it's a real issue getting
them out of the ground. They'll salvage any useful bits they can for the
manufacturer to reuse wherever the next *funded* project is about the
start tunnelling (which isn't Crossrail 2).
