this is the answer to a fairly basic pub quiz question. the stairs are also used for endurance training by long distance runners, at least this way they're undercover. I've never been a runner of any sort, but have climbed UP these stairs twice, when I was younger with no mobility problems. why? "because it's there".

clarification of the above; twice on separate occasions, once to see if I could, much later to see if I still could. and at least 10 years younger than dg is now

A fascinating post. I tend to avoid Hampstead station because the lift moves really fast and it makes me feel uneasy, and no way could I walk up 320 steps.

How many stairs are there at Highgate? If it is so deep shouldn't it be in the top 10 longest? Or is the depth taken from the exit next to The Woodman rather than ticket hall?

Note that Covent Garden with its 193 steps, we are told that it's the equivalent of a 15 storey building.

And at Hampstead with its 320 steps its the equivalent of a 15 storey building.

Umm, TfL? *hello?* How stupid are you...?

Also, there's a (valid) rumour that the Station Supervisor at Hampstead has a log book with times in it - it's an initiation ceremony that goes back years. Whenever a new member of station staff comes to Hampstead they're asked to walked up the steps and are timed to see how long it takes them.

So from the table in the spreadsheet you take the average value for the platforms then subtract 100 from that value in the table to get height above sea level (which may be negative). You then subtract that from the Ground Level Outside Station value to get the distance of the average of the platforms below ground level. For this you need to remember that minus minus is plus. This will give you the depth of the average of the platforms below ground level. This figure of course could be minus indicating that the platforms are about ground level (i.e. on a viaduct). What could be simpler?


So in the case of Hampstead it is

108 - ((149.9 + 149.1)/2 - 100) = 58.5 as you correctly state.

By contrast Goldhawk Road is

5 - (111 + 111)/2 - 100) = -6 so the platforms are six metres above ground level.

Agreed. Although I haven't used average platform level, I've used lowest platform level. That's identical at Hampstead, but quite different at Holborn.

What is a typical height between consecutive floors? Say 3 or 4m perhaps? So Hampstead is towards the top end of that range but Covent Garden well below the bottom end. Both have risers of around 18cm.

We discovered the stairs at (I think!) Covent Garden several years ago, and decided to take them down to the platform. How many steps, we thought, can there be?

A lot. But as DG notes, only by taking the stairs do you realize just how far underground you really are.

I see Hampstead station has a clockwise spiral. Queensway which I often walk down, has an anti clockwise spiral, it's surprising how you can get used to one and not other!

How deep are the jubilee platforms at Westminster? As it seems to take forever to get down to them?
