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?
