Changi Airport Skytrain

The Changi Airport Skytrain is a fully automated people mover system located within the Changi Airport.

The Skytrain serves as an integral part of the airport's inter-terminal transfers, and is operated as part of Changi Airport. The system has 7 stations throughout all three terminals of the airport, and serves both the public and airside areas of the airport.

The system is physically separated into two sections: People Mover System (PMS) North and PMS South. Both sections share a central control room, but has separate maintenance facilities.

PMS North includes stations A, A South and F, and only serves airside areas. PMS South includes stations B, C, D and E, and serves both airside and public areas.

History

Initial opening

The Skytrain system was constructed as part of Changi Airport's Phase II developments, which includes Terminal 2 as well as a second runway. The system was completed and opened in 1990, connecting Terminals 1 and 2 together. This original system used the AdTranz C-100 automated people mover.

Infrastructure upgrades

Replacement and expansion of Skytrain

Starting 2002, the Skytrain system was progressively replaced, to upgrade and extend the system to support the upcoming Terminal 3. This involved the complete replacement of the previous AdTranz system with a new Crystal Mover system, including new tracks and guidance systems, stations, power distribution system, and signalling system.

During the replacement process, the previous system was kept running alongside replacement and installation of the new system, to ensure minimal disruption to passenger service.

The new system began operation in March 2006 for Terminals 1 and 2, and in November 2007 for the new Terminal 3.

Jewel Changi Airport

As a section of the Skytrain on PMS North between Station B (T2) and Station E (T3) runs through Jewel Changi Airport, service between the two stations were suspended on 24 February 2015 to facilitate the construction of Jewel Changi Airport.

Replacement buses are available for airside passengers, while public users moving between Terminals 2 and 3 were advised to take a 5-minute walk through the mezzazine level bridge along Changi Airport MRT station.

The service was resumed for passengers on the airside on 12 April 2019 and landside in July 2019.

Signalling Upgrade and Modification for additional trains

To increase the capacity on the Changi Airport Skytrain, six new train cars were purchased and added to the system in 2019.

The existing shuttle between Terminals 2 and 3 is upgraded to a three-car system, while the shuttle between Terminal 3 and 3 South is upgraded to a two-car system.
