Bangkok Suvarnabhumi Airport Satellite Shuttle ระบบขนส่งผู้โดยสารอัตโนมัติท่าอากาศยานสุวรรณภูมิ

The satellite terminal of Bangkok's main airport (BKK Suvarnabhumi) opened in late 2023, giving the airport additional capacity.
Transferring between the main terminal and the satellite is by this new single rail guided, rubber tyred based system running under the airport apron.
The automated system was supplied by Siemens and based on the Rennes Metro Line B in France.
