Flat and tube line still there, I went back last October for a
visit.......but there is subsidence in that part of the West End of
Glasgow,
close to where 2 lines cross beneath the Great Western Road. A number of
theatres in the city are located above underground lines (Theatre Royal,
Royal Concert Hall, Atheneum, Tron, Kings, Mitchell - during quiet
moments
trains can be heard rumbling nearby. I'm sure it's the same in London
)

It certainly is in Birmingham, where the Repertory Theatre is above the
Monument Lane tunnel into New Street Station. The vibrations can
definitely be felt there!

(Although the nearby Symphony Hall is also above the tunnels and no
vibration is apparent there due to some *very* extensive soundproofing
which sees the hall effectively "float" on rubber insulation.
Expensive but effective.)

Must be the same as/similar to the Royal Concert Hall in Glasgow, it is
directly above the Underground (Circle Line) and was built on rubber 'shoes'
to absorb the vibrations from trains passing underneath. I imagined the
Symphony Hall in Birmingham was the same, good to have it confirmed. Thanks
Ian.

You're welcome. I occasionally get to guide people through there and
have in the past even been lucky enough to go down into the "basement"
and see the insulation itself.

I'm ashamed to say that I've never been inside the Royal Concert Hall in
Glasgow. I hope it's at least as good as "ours"! ;-)

Relatives of mine live in the Walthamstow area, and sure enough every few
minutes there's a heavy rumbling coming through the floor! it's so clear
that you can actually hear what sounds like the wheels running over the rail
joints!
