This is a list of the busiest railway stations in Great Britain on the National Rail network. The figures are collected by the Office of Rail Regulation, and are estimates based on ticket sales in the financial year of 2014–15. The data count entries and exits at any station. Only tickets sold for National Rail services are included. As such, London Underground, special tours, local light rail and heritage railway tickets are excluded. Note that these data cover Great Britain and surrounding small islands (such as the Isle of Wight), not the United Kingdom, and so exclude tickets within Northern Ireland and Eurostar. There are various further limits to the data due to the variety of ticketing options available on rail services within the UK; these are outlined in full in the report on the data. The top 30 stations are shown.
