Train stations with more than 30 million passengers per year are shown.
This list aims to include station footfall from all modes of heavy rail transport.
With many stations, all heavy rail transport is included, such as with U-Bahn systems in Germany.
With other stations however, there may be multiple agencies involved meaning that for the purpose of comparability, they have been compiled into just a single statistic.
A notable example of this is with London stations, which tend to only include figures collected from the National Rail network, meaning that journeys on the London Underground have been added to the total entries and exits.
