Heathrow Terminal 5 Transit

The Heathrow Terminal 5 Transit is an automated people mover system (APM) at London Heathrow Airport in the United Kingdom. It operates in the Heathrow Terminal 5 complex and conveys air passengers between the main airport terminal and its satellite buildings, Terminals 5B and 5C.

History
The Terminal 5 APM transit came into operation at the opening of Terminal 5 in 2008. It was the first ever deployment of the Innovia APM 200 vehicle. Initially the system had two stops, running between the main Terminal 5A and Terminal 5B, operated with two 3-car APM trains. In 2011, the line was extended to Terminal 5C and APM fleet was initially expanded to nine then later to ten vehicles.

Route
The Heathrow Terminal 5 APM vehicles run in a dual-lane tunnel totalling 0.67 km in length. The Transit System has three stations: the main Terminal 5A building (Gates A1-A23), Terminal 5B  (Gates B32-B48),  and Terminal 5C (Gates C52-C66). The people movers operate exclusively "airside", meaning that the system can only by accessed by passengers who have first passed through airport security.

A completely separate personal rapid transit system, the London Heathrow Terminal 5 PRT, operates "landside" between the car parks and Terminal 5.

Vehicles
The transit system is run with a small fleet of ten Bombardier Innovia APM 200 vehicles which convey over 6,500 passengers per hour in each direction.
