The Changi Airport Skytrain is an automated people mover (APM) system serving Singapore Changi Airport, connecting between Terminals 1, 2 and 3. The 6.4-kilometre network is an integral part of Airport operations, offering inter-terminal transfers for both the public and airside areas.

Currently, the system has 7 stations spread across all three terminals. The system operates daily from 5:00 am to 2:30 am at intervals between 1 and 4 minutes. During maintenance hours, replacement bus services are operated.

The system is also physically separated into two areas, North and South, with separate maintenance facilities. The North section includes stations B, C, D and E, and serves both airside and public areas. The South section only serves airside areas, with stations A, A South and F.

All stations within the Changi Airport Skytrain network have platform screen doors, isolating the air-conditioned terminal area from the outside environment, enhancing commuter safety and comfort. Plasma displays indicate the arrival time of the next train.

History

  • 1990: Skytrain opens between Terminal 1 and 2
  • Mar 2006: Upgraded to Mitsubishi Crystal Mover system
  • Nov 2007: Extensions to T3 and South section opens with 5 new stations
  • 24 Feb 2015: Suspension of Station B to E service (T2 to T3) for the construction of Jewel Changi Airport
  • 2019: Signalling and capacity upgrade with 6 new train cars
  • 12 April 2019: Resumption of Station B to E service (T2 to T3) with 3-car service (for transit passengers only)

The Changi Airport Skytrain was built and opened in 1990, in tandem with the construction and opening of Changi Airport Terminal 2. The automated people mover (APM) system then connected both terminals along two parallel tracks, with one used for airside passengers and the other for the public.

Initially, the system utilised Adtranz C-100 trains which operated on a central guideway. Between 2002 and 2006, the system underwent a S$135 million expansion to connect both terminals to the new Terminal 3, as well as a new airside-only system on the South side. The guideway was also converted for Mitsubishi Crystal Mover operations, and the old system was kept operational whilst installation of the new system was in progress. Finally, in March 2006, upgraded system between T1 and T2 became operational, and new lines to T3 opened in November 2007.

Rolling Stock

Changi Airport Skytrain (1)

The Changi Airport Skytrain operates on the Mitsubishi Heavy Industries Crystal Mover rolling stock, with similar technology being used on the Punggol LRT and Sengkang LRT systems. These trains, also known as automated people movers, are rubber-tyred for minimised operating noise within built-up areas and guided by two side rails and a power rail on either side. They operate in both single-car and double-car arrangements, with triple-car operations commencing operations in 2019.

Inside, trains have a spacious interior and wide doors for ease of loading and unloading of baggage.

Skytrain Upgrades

In April 2019, six new train cars were added to the Changi Airport Skytrain network, in addition to the completion of upgrades and additions to signalling and communication systems and related station facilities. The previous two-car shuttle between Station B and E (Terminals 2 and 3) was upgraded to a three-car system, while the previous one-car shuttle between Station A and A South (Terminal 3 and Gates A15 – A21) was upgraded to a two-car system.
