An Oyster card covers the majority of public transport options in London, including buses, trams, Underground Tube, Docklands Light Railway (DLR), TfL Rail services and London Overground services in Zones 1-9, all suburban national rail services in zones 1-9, Thames Clipper River Bus services, and the Cable Car service ...

Excellent question! The Oyster card covers all nine zones of London’s public transport network, from Zone 1 to Zone 9.

Here’s a detailed breakdown of what this means:

The Core System: Zones 1-9

• Zone 1: Central London (the main tourist and business area).
• Zones 2-6: Inner and outer London, including most of the city’s suburbs.
• Zones 7-9: A smaller extension covering some outer areas, mainly to the west and north-west (e.g., parts of Hertfordshire like Watford and Brentwood).

Key Areas and Destinations Covered:

• The entire London Underground (Tube) network.
• All London Overground services.
• All Elizabeth line services (within the London fare zones).
• All Docklands Light Railway (DLR) services.
• All London buses (buses are a flat fare and do not use the zone system—your Oyster is valid on any bus in London).
• London Trams in South London.
• Most National Rail services within the London zones (e.g., trains from central London termini out to the suburbs).

Important Exceptions and Extensions:

While the Oyster card is valid in Zones 1-9, you must be aware of specific stations and routes that fall outside this system, even if they are served by TfL-branded services.
