I've seen the future and it doesn't work, Sydney has a lot of tunnels. Many are under-used and all involve massive land take and community severance at the access points. The London plan has 10 access points, something like this in Poplar east London
Imagine that at Highbury Corner, Old Kent Road, Camden, St.John's Wood, Shoreditch, Battersea park etc.
