train bypassing
Upminster Bridge The London network comprised
368 railway stations within the
London London fare zones. Stations in London (apart from ) are within London fare zones. Some stations outside Greater London, for example
Chigwell in
Essex, are within zones 4–6; many stations outside London are within zones 6–9, for example
Amersham and , but some stations much closer to the Greater London boundary, like and , are not in any zone. London has an integrated ticketing system via the Travelcard or
Oyster card for buses,
Docklands Light Railway, suburban rail, tram, Underground and Overground. Unlike cities like Liverpool, Sydney and Paris, several operators provide suburban rail services, but all are part of the National Rail system and ticketing is integrated. Some operators have government contracts but others, such as Southeastern, are owned by the state. Most stations are served at least every 20 minutes, with many stations and routes having four, six or more trains per hour. Importantly, TfL exhibit a long term ambition to bring many of these separately-operated suburban lines under their control, specifically those which terminate nearer the Greater London boundary. They state that TfL control of these lines will increase service frequency and capacity, as well as homogenise service patterns across differently-operated lines. Current lines within south-and south-east London are set to be prioritised, considering the currently low levels of service frequency experienced here compared to other parts of London.
