United Kingdom railway station categories

The 2,520 railway stations on the National Rail network in Great Britain are classified into six categories (two of which are each divided into two subcategories) by the Department for Transport. The scheme was devised in 1996 and there was a review in 2009 when 106 stations changed categories. The categorisation scheme is owned by Network Rail, the site landlord of most of the stations. Some stations are in multiple categories, for instance St Pancras is in category A for the surface platforms and C1 for the Thameslink platforms.
Categorisation scheme
Category C stations are sub-divided into C1 (city or busy junction) and C2 (other busy railheads). Category F stations are sub-divided into F1 (basic) and F2 (below 100,000 journeys per annum).
