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