Each day more than 2,000 trains, over half of them stopping, pass through the station, more than through any other station in Europe. At peak times up to 200 trains per hour pass through of which 122 stop. It is not the busiest station by number of passengers, most of whom (about 430,000 on a weekday, of which 135,000 are at rush hours) pass through. Interchanges make some 40% of the activity and on that basis too it is the busiest station in the UK.
