Travelcard Zone 1
Fare zone 1 is the central zone of Transport for London's zonal fare system used by the London Underground, London Overground, Docklands Light Railway and National Rail. For most tickets, travel through Zone 1 is more expensive than journeys of similar length not crossing this zone. The zone contains all the central London districts, most of the major tourist attractions, the major rail terminals, the City of London, and the West End. It is about 6 miles (9.7 km) from west to east and 4 miles (6.4 km) from north to south, approximately 45 km2.
London is split into six approximately concentric zones. The boundary of Zone 1 corresponds roughly with the Underground's Circle line covering the West End, the Holborn district, Kensington, Paddington and the City of London. Old Street, Angel, Pimlico, Tower Gateway, Aldgate East, Euston, Vauxhall, Elephant & Castle, Borough, London Bridge, Earl's Court, Marylebone, Edgware Road, Lambeth North and Waterloo are in zone 1 but not in or on the Circle line. Every London Underground line has stations in zone 1. Underground stations within this zone are typically close together; for instance Covent Garden and Leicester Square are only 0.3 kilometres (0.2 mi) apart, the smallest distance between any two stations in the network. The zone originates from two central London zones that were created on 4 October 1981 named City and West End, in which flat fares applied, replaced in 1983 by Zone 1.
