Actually the Crossrail tunnel from the Great Western main line to Chiswick
will be 17 - 18 metres below the surface, which I think is about average
for tube tunnels in London.

Even in Central London, the Crossrail tunnels will run *above* the Jubilee,
Northern, Central, and Piccadilly lines in the Oxford Stret/Holborn area.
There is a vertical section through the central part of the route at

yes - I did say "likely to be", not definitely.

anyway - are you collating these comments as some sort of evidence to
mount a challenge to the Crossrail or to stop a challenge?

Crossrail have said that they will design the tunnels and tracks "with the
aim that noise levels in overlying buildings will be below the significance
criteria of 40 dB(LAmax,S)". That doesn't mean much to most people, and I
wanted to find out what was being experieced at present. No comments so
far from the JLE, which would be interesting as an example of a modern
line.
