some basic Info :
Started operations in 2002.
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.[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. 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.
