On July 17, a total of $682.5 million worth of contracts were awarded for four Jurong Region Line (JRL) by The Land Transport Authority (LAT).
Among the contracts are JRL’s communication system (J160), provision of half-height platform screen doors and signalling system provision (J152), construction of 3 JRL stations as well as their associated viaducts (J109) and integrated supervisory control system delivery (J155) according to a release by the LTA.
Awarded to a joint venture of Yongnam Engineering & Construction and Daewoo Engineering & Construction is the construction and design of 3 JRL stations as well as their adjoining viaducts that is worth $320.4 million.
The project covers the construction and design of Jurong Town Hall, Toh Guan and Pandan Reservoir viaducts and stations which extends up to 3.6 kilometers.
Toh Guan station will cater to the residential developments that exist around the Jurong East Central and other establishments such as various worship places and schools such as Crest Secondary School.
It expected to begin construction for the three stations on a later part of the year, according to the LTA.
They added that residents, specially commuters will be able to utilize the said stations upon the completion of the JRL and notable savings in time travel can be expected.
Daewoo Engineering & Construction is currently involved with Steven MRT station along the Thomson-East Coast Line. The Canberra station as well as the North-South Corridor is under the construction of Yongnam Engineering & Construction.

In the meantime, a $215.5 million JRL construction of its half-height screen doors for their platform and it’s signalling system provision (J152) is awarded to Siemens Rail Automation and Siemens Mobility Pte Ltd consortium.
It includes manufacture, design, installation, supply, commissioning and testing of the entire JRL’s signalling system. The signalling system will fully support automated train operations. The predictive maintenance on the life cycle of the system will be enabled through the condition monitoring feature.
According to LTA the signalling system that Siemens has is used around various metros around the globe including the Mamaray Rail Tube located in Istanbul, Este that is in Madrid and Metro L2 that can be found in Changsa. It is also the same system used in Singapore’s Downtown Line (DTL).
The other two contracts include JRL’s communications system (J160) and a provision for its integrated supervisory system or ISCS (J155). These contracts are worth $146.6 million and were both awarded to ST Engineering Electronics.
Efficiency on rail operations is vital because it provides a basic framework that enables the Operation Control Centre, Passenger Service Centre and Depot Control Centre of the rail line to remotely control and supervise mechanical and electrical services and systems including civil equipment, explained LTA to the importance of ISCS.
Comprising the communications system of the JRL are sub-systems that include public addresses, video surveillance, telephone and communications backbone networks, travel information and digital trunked radio, added LTA.
Currently, ST Engineering is involved in Circle Line 6’s ISCS and communication systems. This also includes the extensions project for DTL3.
