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 in Asia.[1] The Changi Airport Skytrain operates from 0500 to 0230 daily.[2] Traveling on the Skytrain is free and an inter-terminal journey takes approximately four minutes. All stations are equipped with 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 MRT Station on 27 February 2002, the Skytrain is able to connect passengers at Terminal 1 to the MRT station entrances located at Terminals 2 and 3.[3]

Rolling stock[edit]


The trains operating on the Changi Airport Skytrain are the Mitsubishi Crystal Movers manufactured by Mitsubishi Heavy Industries.

Initially, the Skytrain rolling stock consisted of Adtranz C-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 Changi Airport Terminal 3 and the projected increase in demand as the airport expands.[4]

Changi Airport Skytrain was previously operated with Adtranz C-100s in the 90s.

The previous rolling stock of Adtranz C-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 C-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, 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 opened in March 2006 between Terminals 1 and 2 and the connection to Terminal 3 opened in November 2007 during Terminal 3's open house.

As of 2016, the Changi Airport Skytrain uses the Mitsubishi Heavy Industries Crystal Mover automated people mover. This rolling stock entered service in 2006 and replaced the 16-year-old Adtranz C-100, making this the second generation of rolling stock in Changi Airport's Skytrain network.

Exterior design[edit]

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 Line and Punggol LRT Line. The Changi Airport Logo is pasted on the side of each train carriage, with the train fleet number on the middle of each carriage.

Interior design[edit]

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 other 4 trains remain at the depot at Terminal 1.

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.

Train formation[edit]

The configuration of a Mitubishi Crystal Mover in revenue service is M in single car mode and M-M in dual car mode

Redevelopment works[edit]

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.[5]

Future expansion[edit]

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.[6]
