Some residents who live above the proposed line of the Crossrail tunnels
are concerned about possible noise and vibration in their homes when the
trains are running. Is there anyone on utl who lives or works directly
above an existing tube (not sub-surface) tunnel? If so, do you experience
any noise and vibration?

I don't live above a tube tunnel. However the Crossrail tunnels are
likely to be far deeper than tube tunnels. They will also be constructed
to far higher standards than any tube line in London barring the recent
DLR and JLE tunnels. While I don't think anyone can provide a guarantee
that there will be no noise I would say the risk from modern
infrastructure design and modern rolling stock will be low. Obvious
areas of potential environmental harm will have to be identified and
mitigated / removed in order for the project to proceed.

Similarly, have you had any cracks and subsidence? There was a report in
March 2002 that the land above the line of the JLE had sunk by the odd
centimetre.

Not aware of any JLE subsidence but there are provisions in the
legislation that allowed construction to put right any damage that is
demonstrably caused by the line. Such provisions are standard practice
and usually put in place to deal with issues raised by objectors to the
scheme.
