Three of London's airports provide varieties of automated people mover (APM) along guided tracks to shuttle passengers between terminals.
These small-scale transport systems operate independently of London's main transportation network.

The Gatwick Airport inter-terminal transit, originally built in 1983 and refurbished in 2010, was the first airport driverless train system outside the USA; a similar system, the Stansted Airport Transit System, was opened in 1991 at Stansted Airport to provide airside terminal transfers.

At Heathrow Airport, an automated people mover system called the Transit operates airside at Heathrow Terminal 5, and since 2011, a personal rapid transit system called Heathrow Pod has operated between Terminal 5 and the car parks.
