Changi Airport Skytrain is a people mover system that connects Terminals 1, 2 and 3 of Singapore Changi Airport. Opened in 1990, it was the first auto-guided system in Asia.(1) The Changi Airport Skytrain operates from 0500 to 0230 daily and operates at 1 to 2 minute intervals.(2) Travel on the Skytrain is free and an inter-terminal journey takes about 90 seconds. All stations have platform screen doors, are air conditioned and have plasma displays indicating the arrival time of the next train.

With the opening of the Changi Airport station on 8 February 2002, the Skytrain is able to connect passengers at Terminal 1 to the MRT station entrances located at Terminals 2 and 3.(3)

Initially, the Skytrain rolling stock consisted of Bombardier Innovia APM 100s, jointly built by Westinghouse and Adtranz (acquired by Bombardier). In 2002, work began on a new S$135 million Mitsubishi Crystal Mover-based system to accommodate the planned opening of Terminal 3 and the projected increase in demand as the airport expands.(4)

The previous rolling stock of Bombardier Innovia APM 100 ran without a second carriage per train (as opposed to the current Mitsubishi Crystal Movers, which runs with two carriages per train), and the first two platform screen doors of each station were for emergency purposes (The Innovia APM 100s stopped at the outer half of each station, with two doors on each half.).

The third rail, formerly at the centre of the track, was moved to the side. The new system opened in March 2006 between Terminals 1 and 2 and opened the connection with Terminal 3 in November 2007 during Terminal 3's open house.

Rail connection between Terminal 3 (Station B) & Terminal 2 (Station E) will be closed from 24 February 2015 until 2018 due to the construction of Jewel Changi. The existing shuttle between Terminal 3 (Station B) & Terminal 2 (Station E) will also be upgraded to a 3-car system, whereas the shuttle between Terminal 3 & 3 South will be upgraded to a 2-car system. To connect between Terminal 2 and 3, commuters are required to travel via the mezzanine level bridge, above the MRT paid link , which is at Basement 1.

Future Expansion

Plans are in place for future expansions of the system. These would include a 2-station single lane shuttle of about 500 m in length serving the southside of Terminal 2 from Station F, and a 4-station dual lane shuttle of about 1400 m to serve a future Terminal 4.(5)

Between Terminal 2 and 3, it will be upgraded from 2-car to 3-car system while Terminal 3 to Terminal 3 South will be upgraded from 1-car to 2-cars system. And will be purchased 6 trains upsized from 16 to 22 from a same train specification and will be purchased by 2019.
