Travelcard
These give you unlimited travel on National Rail, London Overground, the Underground, Buses, Docklands Light Railway and Tramlink services within London Zones 1-6.
If you are travelling from outside London Zones 1-6, you can add a Day Travelcard to an Anytime, Off Peak or Super Off Peak Day Return ticket and save yourself money on buying separate Day Return and Travelcard tickets. The combined ticket gives you one return trip from your station to the first station in London Zones 1-6, then unlimited travel within Zones 1-6.
Please note, that from Sunday 20 May 2012 you will need a season ticket photocard when buying or renewing a 7-day Travelcard. This includes travel anywhere within the London Zonal area.
Travelcard Season ticket can also be added to your rail season ticket.
Oyster Pay As You Go may be a cheaper option if: your journeys are wholly within London Zones 1-6; or, you are travelling into London from a station outside Zones 1-6 and only plan to make a few journeys within Zones 1-6.
