How deep does the london underground go?

Question

Does anyone know how deep, in meters preferably, does the tube go?
How far under the weight of London do we actually travel?
I've checked the Transport for London sight and it doesn't give this information.

Also what is the maximum speed the trains do travel at?

Answer 1

It varies. The 'big train lines' like the Met and District are not very far below street level. They were built on the 'cut and cover' principle whereby a street was lifted, the trench dug to take the railway, and then the street reinstated on top. The depth of the true 'tube' lines varies considerably, there is no uniform depth. They go deep enough to avoid the usual services, gas, water, sewerage pipes, electrical and telephone cables etc. The deepest station is Hampstead on the Northern line lying 58.5 metres below street level. I am not sure if any running lines beat this

Hi. Northern line near Hampstead. The old ears go pop on surfacing. Check out the 3D map thing from London Underground. It confirms the ear-popping scenario. Cockfosters is nice, rolling across the feilds overground, but I digress. Oh, what was the other question, then ? Happy travelling on the system. Bob.

Answer 4

Here's what I found on Wikipedia:

The deep-level or "tube" lines, bored using a tunnelling shield, run about 20 m below the surface (although this varies considerably), with each track in a separate tunnel lined with cast-iron rings. These tunnels can have a diameter as small as 3.56 m (11 ft 8.25 in) and the loading gauge is thus considerably smaller than on the sub-surface lines. Lines of both types usually emerge onto the surface outside the central area, except the Victoria Line, which is in tunnel except for its depot, and the very short Waterloo & City Line, which has no non-central part and no surface section. Only 45% of the Underground is in tunnel.

Answer 5

On the Metropolitan line, trains can reach over 60 mph. The deepest lift shaft is Hampstead - 55.2m/181ft
