List of railway lines in Great Britain

This is a list of railway lines in Great Britain that are currently in operation, split by country and region.

Railway lines in England and Wales, as of 2010

There are a limited number of main inter-regional lines, with all but one entering Greater London.^[1] The line from London to the Channel Tunnel is the only line designated 'high speed', although the other main routes also operate limited-stop express services.

The bulk of the secondary network is concentrated in London and the surrounding East and South East regions; an area marketed by National Rail as London and the South East. The majority of these lines are radial to London.^[2] There is a further concentration of routes around Birmingham in the West Midlands^[3] and in the urbanised part of northern England that stretches from Liverpool in the west, via Greater Manchester to Leeds in the east.^[4]

Some areas, such as Wales and Scotland, have relatively sparse railway provision.^[1] There are local lines throughout all areas of Great Britain with some services designated as community railways.
