Underground line under house - experiences pls!

[Mangosoup]

I am considering purchasing a property that has a tube line running underneath and was hoping to get advice/feedback on what it’s like to live in such a property in terms of noise levels/vibrations/any other issues to be aware of. We can hear a low
level hum/whooshing sound in the basement and a couple of stories up, though it’s loudest in the basement of course.
Didn’t bother us too much during the viewing.
But we wouldn’t know whether it’s more noticeable in evenings - especially with 24 hour service on weekends - or if it caused any minor vibrations/movement (assume this would cause actual physical damage over time and therefore should be a known issue in the area?).
Having checked google maps & other sources, it’s more common than I’d realised in the area (though doesn’t seem to affect property values) and it’s unclear if it runs right under the house (if that makes any difference to anyone’s experience!).

First question is which tube line! Some lines are just under the surface, others are many tens of meters deep underground, which I imagine would make a huge difference.

I once lived in a house above the Northern Line, not particularly deep at that point. There was vibration but you got used to it.

I use to live in a flat in a building over the northern line (near Stockwell). We were 2nd floor but it was mostly noticeable at night / Sunday evening, when there was obviously less background noise around. It basically sound like the washer was constantly running - a low level hum. This was pre night tube so i cant say how disturbing it was, but i definitely noticed its absence when we moved out.

Funnily enough I used tio live in Stockwell too - our 1st and 2nd floor flat in converted house was over the Northern Line too (I think -- although it may have been Victoria as we were close to the station and I'm not exactly sure of the route). We could certainly hear it late at night from time to time and first thing in the morning - however it didnt ever wake us up it was just that could hear the sound every so often. I actually really enjoyed hearing it - it made me think of the exciting life I was living in London!

The bigger issue for us was the Heathrow approach - when we first moved there at 5:30-6 every morning the planes starting their desecent over South London used to wake me up fairly regularly. In a big city theres always noise...

We used to live directly above the Northern line. Panicked when we first moved in but we were completely used to the noise within about two weeks.

We had the ground and lower ground floors. It was definitely more noticeable on the lower ground, which is where our bedrooms were, but was still only ever a low level, distant rumbling sound, it reminded me a bit of thunder.

Weirdly I grew to find the noise quite relaxing. Like a white noise type of thing at night.

Our opinion was that if you want to live in central(ish) London, there will inevitably be some kind of noise. We has previously lived on a fairly busy road with a lot of traffic and buses. That was 100x worse than the regular rumble of the tube.

Many houses in inner London will be over a tube line and given the age of both the tube network and the housing stock, they're likely to have co-existed a long time. If there's no sign of cracking or damage then it's unlikely that any will be caused in the future. Whether you can deal with the vibrations eg is something only you can decide. I suspect you'd get so used to them, in time you would hardly notice.
