Tube & Bus
The easiest way to travel on tube and bus is using the Contactless and Mobile pay as you go.
Sign up with your Visa/MC and just use the app to touch in and out.
This should work on every type of transport.
As far as routes:
Just use google maps for this – is incredible
Will give you the exact tube/bus stop and the exact time
Elizabeth Line
Best transport from Heathrow into London. Generally, if you have a large distance to cover – take the Elizabeth line. Otherwise stick to the tube and buses.
National Rail
National Rail provides passenger train services for all of England, Scotland, and Wales.
Buy your tix online a few days before to save money.
Pay VERY close attention to the times – prices can fluctuate wildly – sometimes by £100. If you avoid rush hour times (peak), then the prices are considerably less.
There are 18 National Rail terminal stations in central London. All of them are placed conveniently in the direction of the area you will be heading towards. There are excellent services at most, i.e. grabbing a picnic for the journey, coffee etc.
Thames Clipper
An absolutely fabulous way to travel around London. See all the sites along the Thames from comfortable seats. Great, accommodating schedules for every destination.
London Overground
This comes in handy when you are in the outskirts, the burbs of London. You will probably never use this -but thought I’d mention it.
Docklands Light Rail
Once again, you will probably never use this…
Serves the redeveloped Docklands area of London and providing a direct connection between London’s two major financial districts, Canary Wharf and the City of London.
IFS Cloud Cable Car
This would be rarely used. It is a gondola that crosses the Thames from the Greenwich Peninsula to the Royal Victoria Dock.
