Heathrow is unusually well connected by rail. The Elizabeth line, London Underground and Heathrow Express all serve airport travelers, but their best use depends on your destination, price preference and luggage.
Elizabeth line
TfL states that Elizabeth line journeys between Paddington and Heathrow can take as little as 28 minutes and services call at the airport rail stations for Terminals 2 & 3, Terminal 4 and Terminal 5. It also serves central stops beyond Paddington.
Underground
The Piccadilly line can be useful for destinations along its route and is integrated into the wider Tube network. It typically makes more stops than the dedicated airport express, so compare total journey time to your actual hotel.
Heathrow Express
The dedicated express targets Paddington. It can be attractive when Paddington or a nearby connection is your priority, while the Elizabeth line may reduce transfers for other parts of central London.
Terminal first
Before buying or tapping in, confirm which terminal you are using. Heathrow has separate rail stations serving Terminal 4, Terminal 5 and the Terminals 2 & 3 area.
