I do wonder if there's room undeneath the roadway for either a huge
long road underpass, or a very shallow subsurface tram or underground
line. The Central line is presumably rather deeper, and although there
will be pipes and cables and things, dealing with these is a matter of
detail (admittedly a very expensive one) rather than a showstopper.

Although the entrances are often in the ground floor of buildings,
aren't all the underground station ticket halls immediately below the
road surface? - relocating those seems rather more than a matter of
detail, I reckon...

Curses, foiled again!

That's the problem with google. You can usually find what you're looking
for with a fairly simple search. It's knowing *which* fairly simple
search out of the millions of possible fairly simple searches you need
to use to find it ;-) -- Paul D
