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. 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. There is a further concentration of routes around Birmingham in the West Midlands and in the urbanised part of northern England that stretches from Liverpool in the west, via Greater Manchester to Leeds in the east. Some areas, such as Wales and Scotland, have relatively sparse railway provision. There are local lines throughout all areas of Great Britain with some services designated as community railways.
