Integrated Speed and Position Supervision System (iSPS)

 Integrated Speed and Position Supervision System panel and driving console


Project Description

The Corporation strives to provide a safe and reliable service to customers and always seeks continuous improvement. Through a rigorous process of research, design, production and testing, MTR engineers successfully combined the mature and widely used technology of Global Positioning System (GPS) and Radio Frequency IDentification (RFID) to develop the “Integrated Speed and Position Supervision System” (iSPS). During operation, the speed data as well as the position of Light Rail vehicles will be relayed back to the Light Rail Operations Control Centre via a mobile communications network for real-time monitoring. Train captains would receive an audio reminder from the system when the speed of the Light Rail vehicle is about to reach the limit of the section being traversed.

Version 1.0 of iSPS developed by the MTR engineering team is patented in Hong Kong and has been adopted across the whole Light Rail network since 2021. The team is launching an upgraded version with an additional function of inter-vehicle management and is applying for a patent for the in-house development functions of the 2.0 version.

In response to changing environment, the Corporation will explore other features to add to the system for continuous improvement in providing safe and reliable service to customers.
