On the Underground, leaving a station, there are white numbers on sky-
blue boards. What do they mean?

The number of carriages that are out of the station. They enable the
driver to judge if he is still in the station should the passenger
alarm be activated.

Thanks. Also, why are they spaced differently and different stations?

Because they are "If you brake /now/ then this is the number of cars that
will be at the platform when you stop".

The spacing can therefore be affected by the gradient (and the gap
between '4' and '5' is smaller than the gap between '1' and '2'
because the train will be going faster).

Er, that should be the other way round, of course.

Thank you. I see it now.

No they're not. Not on the Picc at least, they indicate how many cars
you are out so that you know whether to brake or not. They are all the
same distance apart and the 6 car mark is exactly a train length out of
the platform.

Other lines may vary but I don't think they do as that's what's in our
training.

The ones on the Northern Line definitely vary. Southbound out of East
Finchley (steep downhill) they almost touch each other.
