In this guide
London’s transit network is best understood as a web of interconnected systems. While the Underground is the most famous, trains, buses, trams, river boats, taxis, cable cars, walking and cycling each offer advantages depending on your route.
The short version: take the Tube or Elizabeth line for rapid central trips, buses for short hops and sightseeing, National Rail or Overground for outer districts, and walk when destinations are closer than the map implies. Always double-check airport transport options before booking tickets.
London transport at a glance
| Transport | Best for | Oyster or contactless? | Main limitation |
|---|---|---|---|
| Underground | Fast central journeys | Both | Hot, busy and not fully step-free |
| Elizabeth line | East-west travel and Heathrow | Both in the Oyster area; contactless continues to Reading | Central trains can be crowded |
| London Overground | Crossing inner and outer London without Zone 1 | Both | Routes have several branches |
| DLR | Docklands, Greenwich, Stratford and London City Airport | Both | Primarily serves east and southeast London |
| National Rail | Suburbs, airports and longer cross-London journeys | Both only within the relevant pay-as-you-go area | Oyster boundaries vary |
| Bus | Short journeys, night travel and street-level sightseeing | Both | Traffic can make times unpredictable |
| Tram | Croydon and parts of south London | Both | Small geographic network |
| River Bus | Scenic east-west journeys along the Thames | Both, with separate river fares | Less frequent and usually dearer than rail |
| Cable car | Views and crossing between Greenwich Peninsula and Royal Docks | Both, with a separate fare | A short specialist route |
| Black cab | Door-to-door travel and accessible vehicles | Card widely accepted | Usually more expensive |
| Private hire and Uber | Pre-booked door-to-door journeys | Pay through the operator | Traffic, surge pricing and pickup restrictions |
Use the TfL Journey Planner or TfL Go app for real-time routing and service updates. Citymapper and Google Maps work well for comparisons, but TfL remains the definitive authority on service status and fares.

Underground: the fastest central network
The London Underground covers 11 lines connecting key central sights. It is typically the fastest choice when your start and end points are near a station.
Navigating is simple once you know your line, direction and terminus, though some lines branch off. Keep in mind that step-free access is not universal and deep-level trains can get hot and crowded.

Elizabeth line: fast east-west travel
The Elizabeth line links Shenfield and Abbey Wood in the east to central London, Heathrow and Reading in the west. Its spacious, air-conditioned trains are ideal for travellers with luggage or longer trips.
Oyster cards are valid as far west as West Drayton, including Heathrow, but do not cover Iver through Reading. Contactless payments are accepted along the entire line.

London Overground: useful orbital routes
The London Overground is great for navigating around London without routing through the city centre. Its six named lines reach districts such as Richmond, Stratford, Hackney, Croydon, Barking, Watford and Chingford.
Every Overground train is air-conditioned, and Oyster cards work across the whole network. Pay attention to train destinations, as several routes split into distinct branches.

DLR: Docklands and London City Airport
The Docklands Light Railway (DLR) is a driverless train system serving Bank, Tower Gateway, Canary Wharf, Greenwich, Stratford, Woolwich, the Royal Docks and London City Airport.
All stations feature step-free street-to-platform access. Grab the front seats if they are open for unmatched views of the tracks ahead.

National Rail: more important than many visitors realise
National Rail connects London’s major terminal hubs with suburbs, regional airports and destinations across Great Britain. It can often be the fastest option inside London itself: Thameslink cuts straight through the centre, and suburban rail serves areas lacking Tube stations.
Oyster and contactless cards work on many in-city National Rail routes, but validity boundaries differ. A train line might accept Oyster for part of a run before travelling outside the pay-as-you-go zone.

London buses: useful, affordable and scenic
London’s iconic red buses reach virtually every neighbourhood. They are often convenient for short trips where Tube stations are spread out, and sitting on the top deck offers great city views.
Buses are completely cashless. Simply tap in once on the yellow reader when boarding using Oyster or contactless; there is no need to tap out. The Hopper fare gives you unlimited bus and tram transfers within one hour using the same card or device. All buses are wheelchair accessible, though space can be competitive during busy hours.
Night routes run 24 hours or operate under dedicated N prefix numbers after hours. Traffic delays mean bus travel times are less fixed than train schedules.

Trams: south London’s local network
London Trams serve the Croydon area, offering branches to Wimbledon, Beckenham Junction, Elmers End and New Addington. They connect directly with National Rail, the Overground and local bus routes.
Oyster and contactless are fully accepted. Tap in at the platform validator before stepping onto the tram; unlike the Tube, most stops do not use ticket barriers.

River Bus and river tours
The Thames functions as both a transport option and a top scenic attraction. Uber Boat by Thames Clippers runs scheduled River Bus routes connecting piers across west, central and east London. Private tour companies also offer circular and point-to-point sightseeing trips.
Oyster and contactless work for River Bus trips, though river fares use a distinct pricing structure from standard rail and bus tickets. While boat travel can be slower and pricier than trains, it is a great choice when you want the journey itself to be part of the sightseeing experience.

London Cable Car
The IFS Cloud Cable Car spans the Thames between Greenwich Peninsula, near The O2 and North Greenwich station, and the Royal Docks, near ExCeL and Royal Victoria DLR.
The ride is brief and uses its own dedicated pricing. You can pay by Oyster or contactless, but it is best enjoyed as a scenic feature that also functions as transport.

Black cabs, minicabs and Uber
London’s official black cabs can be hailed from the street, picked up at ranks or booked through an app. All fares are metered and regulated by TfL. They feature full wheelchair access and drivers with extensive Knowledge of city streets.
Uber and other minicab services are private hire vehicles. These must be booked in advance through a licensed operator; never enter an unbooked vehicle soliciting fares. Always double-check the licence plate, driver details and car model in your app before getting in.
Door-to-door trips are helpful when carrying heavy luggage, travelling late at night or avoiding complex train connections. However, central congestion and airport distance can quickly raise costs.

Travelling to and from London’s airports
Six major airports serve London. Since airport names do not indicate which central station is nearest, pick a route based on your hotel’s location rather than defaulting to pricey express options.
| Airport | Main public-transport choices | Oyster guidance | Detailed guide |
|---|---|---|---|
| Heathrow | Elizabeth line, Piccadilly line, Heathrow Express, coach and local bus | Oyster and contactless are accepted on the rail and Tube routes | Heathrow Airport to London |
| Gatwick | Thameslink, Southern, Gatwick Express and coach | Oyster and contactless are accepted on many London–Gatwick rail journeys; special fares apply | Gatwick Airport to London |
| Stansted | Stansted Express, coach and pre-booked transfer | Contactless is accepted; Oyster is not | Stansted Airport to London |
| Luton | Thameslink or East Midlands Railway to Luton Airport Parkway, then the Luton DART; coach | Contactless is accepted; Oyster is not | Luton Airport to London |
| London City | DLR, local bus, taxi or private hire | Oyster and contactless are accepted on the DLR | London City Airport to Central London |
| Southend | Greater Anglia train, local bus, taxi or pre-booked transfer | Contactless is accepted; Oyster is not | Southend Airport to London |
Heathrow
The Piccadilly line is usually the cheapest direct rail option; the Elizabeth line is faster and more comfortable for central London; Heathrow Express offers a premium nonstop link to Paddington. Choose based on your final hotel location.
Gatwick
Gatwick Express heads to Victoria station, while Southern also serves Victoria, and Thameslink runs directly through London Bridge, Blackfriars, Farringdon and St Pancras. Taking Thameslink can help you skip a Tube transfer.
Stansted
The Stansted Express connects the airport directly to Tottenham Hale and Liverpool Street. Express buses serve several London locations and run through the night, though you should budget extra time for road traffic.
Luton
Trains arrive at Luton Airport Parkway rather than the terminal doors. The Luton DART shuttle links the station to the airport. Thameslink offers direct trains into central hubs, alongside various coach lines.
London City
London City is the only major airport located directly inside TfL’s core rail network. The DLR connects it to key hubs such as Stratford, Canning Town and the Bank financial district.
Southend
Greater Anglia trains run from Southend Airport to Stratford and Liverpool Street. Check schedules for the last train if arriving late, as road options take significantly longer.
Walking and cycling
Central London is far more walkable than the iconic Underground map suggests. Walking between close stations, such as Leicester Square and Covent Garden, is often faster than taking the Tube and lets you experience the street life along the way.
Santander Cycles and docked e-bike brands offer quick bicycle rentals. Always check designated parking zones before finishing an app-based ride, as leaving bikes outside approved bays can incur heavy fines.

How to choose the right option
Run through these steps when planning trips:
- Is the destination close enough to walk?
- Is there a direct train or Tube route available?
- Would a bus avoid a difficult station transfer or offer better views?
- Do you need step-free access or extra room for bags?
- Is the transport leg intended to be a scenic experience, such as a river boat or cable car?
- Are planned maintenance, strikes, road traffic or late-night adjustments affecting your line?
For airport runs, build in plenty of buffer time and confirm both train schedules and terminal numbers. For all public transport, stick to the same Oyster card or contactless device every time you tap in and out.
