The London station group

The London station group is a ring of eighteen stations served by the National Rail network in central London, England. Most are terminal stations, although a few are through stations or have a combination of terminal and through platforms. The station group is rendered on tickets as London Terminals. All current stations in the group are in London fare zone 1. The large number of terminal stations is explained by the refusal of Parliament to allow railway lines to enter the centre of London in the 19th century, causing them to form a ring, connected by underground railways. The majority of the larger stations managed by Network Rail are in the group.
