I took a walk today along the Northern Heights from Alexandra Palace to Edgware. Very nice, and along the way I walked under the Dollis Brook Viaduct, which, as everyone knows, is the highest point above ground level that the tube reaches (18m).
This set me wondering. By walking under it, I was 18m below the tube, but how far below the tube can one be?
So, here's the challenge. Where in London can one get, via tunnels presumably, more than 18m below a tube line? I'd imagine that the Victoria going under the SSL would have a good shot.
