In that case, copy foreign lines. Problem solved.
How do they reduce the operating noise? Is it by running mainly
through open countryside, tunnelling under towns, or what?

The Stuttgart-Ulm project in Germany contains a staggering amount of
tunnel - it's virtually a long-distance Tube line.

Weren't we also trying to work out why the UK spent twice as much as any
foreigners on new lines. Are we spending twice as much as that line?

The bits that aren't in tunnel are alongside an autobahn.
