On the Underground, leaving a station, there are white numbers on sky-

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).
