The Changi Airport Skytrain is an automated people mover that connects Terminals 1, 2 and 3 at Singapore Changi Airport. Opened in 1990, it was the first driverless and automated system in Asia. The Changi Airport Skytrain operates from 0500 to 0230 daily and operates at 1 to 2-minute intervals. 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 MRT 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.
Trains operating on the Changi Airport Skytrain is the Mitsubishi Crystal Mover manufactured by MHI.
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.
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. 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.
When it is Crystal Mover train like today, the Platform screen doors have glass windows to let to know when the train comes compared to the past which is small window or no glass window like Elevator Windows which is similar to Miami Airport Skytrain Concourse E.
