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?

Staying overnight in a house in Southgate, some way from the underground
section of the tunnel (which runs under playing fields of the local
college), it is still possible to hear the trains rumble through if you
listen carefully enough late evening or early morning.

Given the location of the house, which was nearly on the High Street,
this is quite surprising.
