Hitachi Rail’s green communications-based train control (CBTC) next-generation signaling project on SMRT trains enables SMRT to achieve a sustainability goal of net zero by 2050. Green CBTC next-generation algorithms leverage advanced data analytics capabilities within the SelTrac CBTC signaling system to reduce energy consumption across Singapore’s north–south and east–west lines (NSEWLs).
The first phase of the project has achieved additional 8% energy savings for automatic trains on the NSEWLs, on top of green CBTC features first introduced in 2017. Annual additional savings are more than 15 million kilowatt hours, which is equivalent to the electricity consumption of about 3,000 households annually.
Hitachi Rail and SMRT announced the completion of the phase 1 milestone of their next-generation green CBTC project at the Singapore International Transport Congress and Exhibition. The project achieved an additional 8% energy savings for automatic trains and marks a significant milestone in collaborative efforts to enhance sustainable urban transportation and to enable operators, such as SMRT, to achieve traction energy savings and contribute to environmental objectives.
