In this guide
London’s transit network is best understood as a web of interconnected, world-class transport systems. While the London Underground (the “Tube”) is the most famous, buses, commuter trains, river boats, trams, taxis, cable cars, and walking each offer unique advantages depending on your route.
💡 Master Transport Snapshot:
- Fastest Central Travel: Take the Underground or the high-speed Elizabeth line.
- Sightseeing & Short Hops: Use London’s iconic red double-decker buses (£1.75 flat fare with 60-minute unlimited Hopper transfers).
- Airports: Heathrow, Gatwick, and London City are linked by train/DLR. Stansted and Luton accept contactless cards, but do NOT accept Oyster cards.
- Paying: Always tap in and out using the exact same contactless card or Oyster card for automatic daily capping.

London Underground (The Tube)
The London Underground covers 11 color-coded lines serving 272 stations. It is almost always the fastest option for travelling within Central London (Zone 1 and Zone 2).
- Operating Hours: Trains run from ~05:30 to midnight Monday through Saturday, with reduced hours on Sunday. The Night Tube operates 24 hours on Friday and Saturday nights across the Central, Jubilee, Northern, Piccadilly, Victoria and Windrush lines.
- Tapping In & Out: Always tap your contactless card or Oyster card on the yellow reader at the ticket gates when entering AND exiting the station.
- Accessibility: Newer stations (and Elizabeth line stations) have full step-free lift access, but many historic deep-level stations rely on stairs and escalators.
🚀 Tube Pro Tip: Walking between close stations in Central London (such as Leicester Square to Covent Garden) is often faster than going down into the Tube station!

Elizabeth Line (High-Speed Cross-London Rail)
Opened in 2022, the Elizabeth line (line color: purple) is London’s newest rail network, linking Shenfield and Abbey Wood in the east to Central London, Heathrow Airport, and Reading in the west.
- Comfort & Speed: Trains are fully air-conditioned, spacious, feature free Wi-Fi, and offer step-free access at all stations.
- Airport Transit: Provides a direct, high-speed connection from Heathrow Airport to Central London hubs like Paddington, Tottenham Court Road, Farringdon, and Liverpool Street in under 40 minutes.
- Payment Limits: Oyster cards are accepted as far west as West Drayton (including Heathrow), but are not valid past West Drayton towards Reading. Contactless cards are accepted across the entire line to Reading.
London Overground & DLR
London Overground (Orange Network)
The London Overground consists of six named orbital rail lines that connect inner and outer London suburbs without requiring you to travel through Central London (Zone 1).
- Avoid Zone 1 Fares: Travelling on the Overground between outer suburbs is often significantly cheaper than Tube journeys because it bypasses Zone 1. Tap the pink route validators on interchange platforms to prove you avoided Zone 1!
- Features: All trains feature walk-through air-conditioned carriages and full Oyster/contactless acceptance.
DLR (Docklands Light Railway)
The DLR is an automated, driverless light-rail network serving East London, Docklands, Greenwich, Stratford, and London City Airport.
- Front Seat View: DLR trains have no driver cabin! Passengers can sit in the very front seat for an unobstructed view of the elevated tracks and skyscrapers.
- Step-Free Access: Every single DLR station features 100% step-free street-to-train access.
National Rail (Suburban Trains & Express Lines)
National Rail lines link London’s major terminal stations (Waterloo, Victoria, London Bridge, Paddington, Kings Cross, Euston, Liverpool Street) to suburbs and regional cities across Great Britain.
- Thameslink Cross-London Line: Thameslink commuter trains run directly north-to-south through Central London (St Pancras, Farringdon, City Thameslink, Blackfriars, London Bridge), offering a fast alternative to the Tube.
- Oyster vs. Contactless Boundaries: Contactless payment is accepted far beyond the Oyster zone. For example, contactless is accepted to Gatwick, Luton, and Stansted airports, but Oyster cards are NOT valid to Stansted or Luton.
🚻 The thing nobody plans for: most Tube stations have no public toilet, and the ones that do are not where you expect. Our public toilets map shows what is open, what costs money and what is free.
London Buses & Trams
Iconic Red Double-Decker Buses
London buses reach every corner of the capital 24 hours a day. They are completely cashless and cost a flat £1.75 per ride.
- Touch In Only: Always tap your contactless card or Oyster card on the yellow reader when boarding. Never touch out when alighting a bus.
- Hopper Fare: Make unlimited bus and tram transfers within 60 minutes of your first tap for just £1.75.
- Sightseeing: Sit on the top deck at the front window for cheap, panoramic city sightseeing (e.g. Route 11, 15, or 24).
London Trams
Operating in South London around Croydon, Wimbledon, and Beckenham, London Trams connect with Overground and National Rail services. Fares match the bus network (£1.75 flat fare). Tap in on the platform reader before stepping onto the tram.
Hop-On Hop-Off Sightseeing Buses
If you want live or audio commentary while travelling directly between major tourist landmarks (Buckingham Palace, Big Ben, Tower of London, St Paul’s), open-top Hop-On Hop-Off Sightseeing Buses (operated by Big Bus, Tootbus, and Golden Tours) offer 24-hour, 48-hour, or 72-hour unlimited passes.
-
Audio Commentary & Guides: Includes multi-language audio commentary, live tour guides, and designated stops right outside top attractions.
-
TfL Differences: Hop-On Hop-Off buses are private sightseeing tours, not part of TfL. They do not accept Oyster or contactless taps and require a pre-booked tour pass.
-
Bonus Inclusions: Most 24-hour and 48-hour pass options include a free Thames river cruise ticket.
