Singapore Land Transport Authority (LTA) awarded the consortium of Siemens Mobility (leader) and Concord Corporation a contract for the design, supply, testing, and commissioning the power supply system for the Jurong Region Line (JRL).
The system will be designed to be upgradeable, with interfaces for connecting power supply system and signalling 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 & track side equipment. Condition monitoring systems will also be provided to enable seamless monitoring of the equipment performance.
“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,” Andre Rodenbeck, CEO for Rail Infrastructure at Siemens Mobility said.
For the JRL, Siemens Mobility was also awarded a contract for the design, supply, installation and commissioning of a Communications-Based Train Control system and half-height platform screen door and a contract for the supply installation and commissioning of depot equipment for Tengah Depot. This project includes the utilisation of Building Information Modelling (BIM) technology that significantly aides interfacing, coordination, design, and planning activities.
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 7 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.
