The its-difficult-to-tunnel excuse no longer holds water in the

So we have new geology in the 21st century? What's changed pray?

Tunnelling technology , what do you think? The channel tunnel was
built through dozens of miles of water bearing chalk under the sea so
I don't think the "its nasty chalk not clay" really cuts it any more
as an excuse not to build tunnels in south london.

Huh? Chalk has pretty similar tunnelling characteristics to clay. It's
the sand in south London that's hopeless. Look at how they built the JLE.
