Mitsubishi Crystal Mover (Changi Airport Skytrain)

The Mitsubishi Crystal Mover is an automated people mover (APM) system for airports and light rail applications manufactured by Mitsubishi Heavy Industries and is based on the Japanese APM standard.

These trains replace the older AdTranz C-100 that operated on the Changi Airport People Mover System (PMS) from 1990 to 2006.

10 train cars operate on PMS North while the remaining 6 train cars operate on PMS South. 6 additional train cars were purchased in 2016 and will be put into service from 2019 onwards.

It operates on an exclusive elevated guideway, unhampered by automobile and pedestrian traffic. Its rubber tyres are extremely quiet as compared to the metal wheels of the MRT.
