Mitsubishi Heavy Industries, Ltd. (MHI) received an order for its Crystal Mover for Changi International Airport of the Civil Aviation Authority of Singapore (CAAS), to serve as the transportation system connecting its terminals where the newly constructed Terminal 3 is a symbol of the New Singapore Changi Airport. The new transportation system is characterized by its innovative and futuristic vehicle design, by a unique design for connecting to a new guideway through the retrofitting of the structure of the existing system, and by realization of the request for a seamless transition service from the existing system to the new system, thus providing a complete system which connects all the terminals, Terminals 1 to 3. This paper reports on the new Crystal Mover and its construction process.
