The one I'm thinking of it a bit higher
Not a lot of wiggle room there as I think Corrour is about 410m...Hmmmmm...

Correct - at 1401 feet or 427 metresI think it is the next station up the P&B line..
... Waunavon

in the Severn Tunnel?
Hampstead Heath will surely be well above sea level though deep below the ground surface
I'll go fo part of the Piccadilly Line in Central London.
London Bridge Northern line platforms. As the Thames is tidal, I'd wager that it's below sea level (but might not be the lowest...)
Bank on the same line?
Let's try the Jubilee Line platforms at Westminster - having now read the question properly
Bank's platforms are 136ft below street level. Is the City really over 31ft above the Thames at street level?
Westminster was verified from London Underground web site.
I have walked many times from Cannon Street station along "Walbrook" which seems to be a slow steady incline. Cannon Street station is high above the "Thames".

Wasn't arguing with the answer, apologies if it seemed that way, I was more surprised that the City is so far above the Thames as I thought the reason for building the Thames Barrier was to stop City traders from getting wet feet...
......
Correct.
Your turn.
I'll take colour light signals. They were however mostly not three aspect but instead simply displayed the aspects that semaphores would have done.3-aspect colour-light signals?
