In partnership with Hitachi Rail GTS Singapore, we are working on the “Next-Generation Green Communications-Based Train Control (CBTC) Project" for our North-South and East-West Lines (NSEWL). This project analyses train movement and energy usage profiles to recommend improvements in timetables and train operations, enabling more efficient use of traction energy.
Phase 1 of the project has delivered around 17 GWh in annual energy savings, enough to power over 3,800 four-room HDB flats. Implementation of the Green CBTC system has progressed, with Phase 2 achieving approximately 10% energy savings on the NSEWL through optimising train coasting points using advanced digital tools. This was enabled through ATS software enhancements and the deactivation of the Service Recovery function, allowing the Automatic Train Regulation system to adopt a more energy-efficient train running profile with reduced acceleration. The overall project is set to achieve up to a 15% reduction in traction energy, enabling greener, more sustainable operations on the NSEWL.
