Cross Island Line in Singapore Set for Siemens Power Infrastructure

A consortium comprising Siemens Mobility and Concord Corporation has clinched a pivotal contract to electrify Singapore’s Cross Island Line (CRL), a cutting-edge digital metro system. This marks Siemens’ third major involvement in the CRL project, following previous successful bids for catenary power systems and the advanced Trainguard CBTC signalling technology, which included the installation of full-height platform screen doors.

The newly secured agreement encompasses a comprehensive scope: designing, supplying, installing, testing, and commissioning the power supply infrastructure. This system will be integral to the CRL’s operations, powering everything from train movement to signalling systems and station facilities.

The consortium’s deal, valued at a minimum of €270 million ($297 million), involves the provision of crucial electrical components:

– Medium Voltage System (22kV): Featuring 22kV GIS panels and service transformers
– DC System (1500V): Including DC panels, dual converter transformers, and converters

To enhance maintenance efficiency for the Land Transport Authority, the consortium will implement a sophisticated Condition Monitoring System alongside an Intelligent Fault Isolation System.

Siemens Mobility emphasized the forward-thinking design of the CRL power supply system: “Our solution incorporates proven modular features, facilitating future upgrades. This approach ensures seamless integration and optimized interface connectivity between power supply and signalling systems, promoting sustainable and cost-effective long-term operations.”

Michael Peter, CEO of Siemens Mobility, expressed his enthusiasm: “Securing this partnership with Singapore’s Land Transport Authority for the Cross Island Line’s electrification is a significant achievement. It reinforces our enduring commitment to delivering comprehensive rail infrastructure solutions, building on our previous implementation of the Trainguard MT Communications-based train control signalling system. Our power supply technology will merge physical and digital realms, ensuring reliable, safe, and fully available electrification while optimizing lifecycle expenses.”

The CRL project represents a milestone in Singapore’s transportation evolution. Construction is slated to commence in 2024, realizing a vision first conceived 11 years ago for a new East-West corridor beneath the island nation’s bustling urban landscape.
