The London station group is a group of 18 railway stations served by the National Rail network in central London. Most are terminal stations, either serving major national services or local commuter routes. A small number are through-stations that are considered terminals for ticketing purposes. All current stations in the group fall within London fare zone 1. Most London terminal stations were developed in the mid-19th century during the initial boom of rail transport. Many stations were built around the edge of central London, stopping at what is now the London Inner Ring Road, because it was prohibitively expensive to build right into the centre, and because each railway was owned by a private company competing with the others. The creation of the London Underground provided a practical connection to the various termini. Many of the stations have been upgraded and modernised to provide a greater capacity and connections to the network; the first London terminus, London Bridge(pictured) has been rebuilt and expanded on numerous occasions, and of the major 19th century terminals, only Broad Street has closed.
