The Changi Airport Skytrain is an automated people mover (APM) that connects Terminals 1, 2 and 3 at Singapore Changi Airport. Opened in 1990, it was the first driverless and automated system of its kind in Asia (though predated nine years by the Port Liner line in Japan). The Changi Airport Skytrain operates from 0500 to 0230 daily. Traveling on the Skytrain is free and an inter-terminal journey takes approximately four minutes.
Since 2006, the trains operating on all Skytrain lines are Crystal Movers manufactured by Mitsubishi Heavy Industries. All stations are equipped with platform screen doors, are air-conditioned and have plasma displays indicating the arrival time of the next train.
Initially, the Skytrain rolling stock consisted of Adtranz C-100s, jointly built by Westinghouse and Adtranz (acquired by Bombardier). Although stations were designed to accommodate two-car trains, the C-100 trains operated in single units, without a second carriage per train, and the two innermost platform screen doors of each station were for emergency purposes (the trains stopped at the outer half of each station, with two doors on each half).

In 2002, work began on a new S$135 million Mitsubishi Crystal Mover-based system to accommodate the planned opening of Changi Airport Terminal 3 and the projected increase in demand as the airport expanded. Among the changes, the third rail, formerly at the centre of the track, was moved to the side, and the platform screen doors were fitted with full-height glass panels, which made it easier for passengers to be able to see when the train is arriving. The new system, now with two carriages per train, opened in March 2006 between Terminals 1 and 2; the connection to Terminal 3 opened in November 2007 during Terminal 3's open house.
The top of the train is painted black, with the bottom of the train painted grey. The side-mounted headlights have a larger surface area, compared to the ones operating on Sengkang LRT Lines and Punggol LRT Lines. The Changi Airport Logo is pasted on the side of each train carriage, with the train fleet number on the middle of each carriage.
The color of the interior is light-yellow. LCD screens are placed at the end of every car, similar to the unused LCD screens on the Mitsubishi Heavy Industries Crystal Mover C810. Unlike all other trains on Singapore's LRT network, it does not have seating in the middle, and only has seating at the end of each train. This is done to allow more floor space for the passenger's luggage, and also for passengers to stand, when the train is crowded. The train that can be boarded, depends on which area one is in. For example, if you were to board from the Public Area, the interior seating color is blue (Sets 01–10), while the Transit Area has an orange color scheme on the seats (Sets 11–16).
In the Public Area, 6 trains will be deployed for service while the 2 trains remain at the depot at Terminal 1 while the other 2 trains will be parked at one of the Terminal 1 Transit Area Station D platforms.
In the Transit Area, 5 trains will be deployed for service while the remaining 1 train remains at the depot at Terminal 3 at Station A South or terminate at one of the Station A platforms.
The configuration of a Mitubishi Crystal Mover in revenue service is M in single car mode and M-M in dual car mode

In 2015, one portion of the Changi Airport Skytrain system connecting Station B and E was suspended due to construction works for the upcoming Jewel Changi Airport. Passengers in the public area will have to use the mezzanine level bridge along Changi Airport MRT Station, and the Skytrain operating between Station A and F in the transit area.
Plans are in place for future expansions of the system. To increase the system capacity of the Skytrain, six new train cars have been purchased and will be rolled out to the system by 2019. The existing shuttle between Terminals 2 and 3 will be upgraded to a three-car system, whereas the shuttle between Terminal 3 and 3 South will be upgraded to a two-car system.
