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.[3][2][4]
Route
The Heathrow Terminal 5 APM vehicles run in a dual-lane tunnel totalling 0.67 kilometres (0.42 miles) 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).[5] The people movers operate exclusively "airside", meaning that the system can only be accessed by passengers who have first passed through airport security.[3][2][6]
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.[3]
