The system will be designed to be upgradeable, with interfaces for connecting power supply and signaling that will meet industry standards.
For this project, Siemens Mobility will specifically provide two high-voltage systems consisting of gas-insulated switchgear (GIS) and Intake Transformers (66kV). This includes a medium voltage system with 22kV Switchgear Panels and service transformers, as well as a 750V DC system and track side equipment. Condition monitoring systems will also be provided to enable seamless monitoring of the equipment performance.
“Siemens Mobility is proud to have been awarded the opportunity by the LTA to provide a power supply system for this important new rail option, one that is projected to put 60,000 more households in Jurong within a 10-minute walk of a train station,” said Andre Rodenbeck, CEO for Rail Infrastructure at Siemens Mobility.
“Our Sitras Sidytrac Live solution for power supply will provide the JRL with a digitalized and automated system that will allow them to set benchmarks for cost-effectiveness, quality, and environmental protection. Furthermore, it will help create a reliable and safe system that will deliver greater transport availability for the people of Singapore,” he added.
The Jurong Region Line (JRL) is Singapore's seventh MRT line, fully constructed on elevated tracks with 24 stations and a length of 24 km. The planned opening will happen in three stages. In 2027 the first 10 stations will be opened, followed by seven stations one year later and another seven in 2029. It will serve both existing and future developments in the western part of Singapore and will significantly improve connectivity of the region and support the development of the Jurong area.
This latest contract builds on a series of other projects Siemens Mobility has been awarded for JRL. In 2020, Siemens Mobility secured the contract for the design, supply, installation and commissioning of a Communications-Based Train Control system and half-height platform screen doors, and in 2021 a contract for the supply installation and commissioning of Depot equipment for Tengah Depot was awarded. This project includes the utilization of Building Information Modelling (BIM) technology that significantly aides interfacing, coordination, design, and planning activities.
This project will build on the already well-established relationship Siemens Mobility has with Singapore that includes providing the power supply system, signaling and the simulation center for the Downtown Line (DTL), the world´s longest suburban fully automated metro line, as well as providing electrification for two other mass transit projects: Circle Line Stage 6 and North East Line extension.
