I lived in a flat for a while which was directly above the Glasgow
Underground's Circle line, between Hillhead and Kelvinbridge. Every 30-60
seconds the floor/walls vibrated when a train was passing underneath. I got
used to it after a while and actually miss it now I'm back living in London.
I now live near Clapham Junction and hear overground trains go by every
30-60 seconds.....but it's not the same as living directly above a tube
line.

The glasgow tube has a frequency of 30-60secs?! Wow!

I live right above the East London line, which isn't very deep (around
10ft down?). There's a rumble every few minutes, but to be honest,
after living there just a short while I really don't notice it at all!
(i notice my upstairs neighbour's telly more!!)

I wouldnt like to be still living there when the extension is done
though unless they really sort out the track as it'll be longer,
heavier and more frequent trains!! (and somebody even suggested they
might use it for freight! Aarghhh!)
