Suvarnabhumi Airport Automated People Mover

The Suvarnabhumi Airport Automated People Mover (APM) (ระบบขนส่งผู้โดยสารอัตโนมัติท่าอากาศยานสุวรรณภูมิ) is an underground automated people mover located in the property of Suvarnabhumi Airport, Bangkok. It opened on 28 September 2023 (the airport’s 17th anniversary) as part of the partial opening of Suvarnabhumi Airport Midfield Satellite Concourse 1 (SAT-1) and connects the main terminal with SAT-1. It is the only airport people mover system in Thailand and is 1 km in length.

Operations
There are 2 stations served by the Suvarnabhumi APM: Main Terminal Building (MTB) station and SAT-1 Building station. Trains operate 24 hours a day at 3-minute intervals, taking approximately 2 minutes each way. All stations are equipped with platform screen doors and information screens.

Rolling Stock
The system uses the driverless NeoVal (AirVal version) with regenerative braking and rubber tyres running on concrete guideways, similar to that of Rennes Metro Line B. Six two-car sets were produced by the Siemens production plant in Vienna, Austria. It has a car width of 2.80m (9 ft 2 in), with each car having 25 seats. Each train set has a capacity of 210 passengers, and upon calculation, the route can handle 3590 passengers per hour one way. It has a maximum speed of 80 km/h.

The train uses the automated TrainGuard MT Communicated Based Control System (CBTC) for signalling.

The first train set arrived at Suvarnabhumi Airport on 15 July 2020.
