What is Travelcard Zone 4?
'''Travelcard Zone 4''' is the fourth outward zone of [[Transport for London]]'s zonal system. The zonal system used for calculating co-ordinated inter-modal [[Travelcard]] fares within [[London]]. In the Travelcard zonal system, London is split into nine approximately concentric zones for the purpose of determining the cost of a Travelcard. The zone is also used for pricing [[London Underground]] and [[Docklands Light Railway]] single journeys, but not journeys undertaken entirely by bus or tram, for which a city-wide flat fare applies. {{LULZones}} [[Category:London Underground]] {{transport-stub}}
