What is the purpose of the "open" buttons on the doors of the London
Underground carriages? On every Underground train I've used, the doors
open automatically at every station. Is/was there a time or place where
they don't open automatically and the buttons must be used?

Yes - the past. It used to be the case, AIUI, that the driver didn't open
all the doors when the train stopped at a station on the surface, at least
if it was cold and/or wet and not too busy. Then, you'd have to push the
button to open the door. However, this seems to have been too confusing
for passengers, and now all doors always open all the time (except when
they don't).

And the future. The air-conditioned S stock will have doors that
automatically close if the train stands in a station too long, to keep
the cold air in, and it'll have working door open buttons to get them
open again.

I have heard that the delay caused while pax (both on the train and
platform) realised that they had to open the doors themselves made it
impossible to keep to the timetable...

Yes they do!! They now have to actually get out onto the platform
before putting the release up! So now passengers furiously stab at the
buttons wondering why the doors have not opened straight away like
they used to!! As well as that, the ex-508 TSO carriages need a longer
button press to get the doors open, so a 455/7, a guard doing it how
they want it and the great unwashed all equals....dismay!!

More than once I've spent a tiring day going around London on the tube
and then done a journey, very late and very tired, on a mainline train
and when it arrived at my station I just stood there like a muppet
waiting for the doors to open, many seconds pass before I realise and
press the button.

some days the brain is in neutral at 1am...

Maybe they should have revolving doors on the trains.

I was once on a crush loaded tube train which pulled into a busy station,
but no-one wanted to board at our particular door, so the outside button was
not pushed. The people inside all had our backs crushed against the curved
door, and when we realised that the door wasn't opening, no-one could work
out where the door button was. Extra door buttons on the ceiling would solve
the problem, or sensors which automatically open [unlocked] doors if the
carriage is crowded.
