If you spot any stations I've missed off my lists, or that shouldn't be in my lists, please let me know.
n.b. I'm using the official names of the stations (so, for example, the two Ashfords don't appear in the first list because one of them is officially Ashford International).
You can find the names of all 2563 National Rail stations in a spreadsheet on the Office of Rail and Road website... or (more accessibly) on Vicki & Geoff's All The Stations website. The Underground, Tyne & Wear Metro, Glasgow Subway, heritage railways and stations in Northern Ireland are not included. If you want to know where a particular station is, the All The Stations website also has a splendid searchable map with a drop down menu.
