The Stansted Airport Track Transit System (TTS) is a fully automated people mover system located at London Stansted Airport in the United Kingdom[1][2]

After opening in 1991 the system was extended in 1998 with an additional two underground stations, to serve a second and third satellite building.[1] The system is "airside" and is accessible only after clearing security.


The Stansted Airport Transit System has 4 (1 disused) stations. All are equipped with Platform Screen Doors.


The system is double track, with 3.2 km (2.0 mi) of track in total[1] and includes a maintenance depot at one end. The system contains elevated and tunneled sections connecting the main terminal building with three satellite buildings, numbered 1 (gates 1 - 19) and 2 (gates 29 - 38) and 3 (40-59) though the transit, currently does not serve satellite 3. due to arrangements with Ryanair not requiring the use of the transit.


There are an original five Adtranz C-100 cars built by Westinghouse for the system. This was increased to a total of nine cars when four new Bombardier CX-100 cars were delivered during the 1998 expansion.[1] During normal operation, eight out of the nine cars will be in service to maintain a 99.98% availability record.[1] The cars can operate as single units or can be coupled to form two or three car trains. The trains are fully automated (driverless).
