Siemens is commissioning one of the world’s longest fully automated suburban metro lines.

Downtown Line Singapore

Commissioning one of the world’s longest fully automated suburban metro lines

A metro line for a growing metropolis

Singapore continues apace with its growth, with over 5.6 million people living in the Asian financial center. But this large population brings infrastructure challenges that will require Singapore to carry on with the expansion of its network with a modern metro line.

The answer to growing traffic challenges

The Downtown Line (DTL) helps manage the volume of traffic and connects people from the outer districts with the inner city. With its existing 34 stations, it offers an alternative, sustainable commuting route and is one of the world’s longest fully automated suburban metro lines.

A vision come true

Trusted partner

Our solutions help Singapore to develop an integrated and sustainable transport system that will last through the decades ahead.

Pioneering transportation

For the Singapore Downtown Line we provide state-of-the-art technology, such as the most advanced CBTC systems with the maximum level of automation (GOA4) and digital services that help to increase overall availability and improve operational efficiency. 

Moving people

With the commissioning of the Downtown Line in 1987 and the extensions that followed, we helped connect people to the city and making travel within the city fast and easy.

Sustainability

With the Downtown Line, we are helping Singapore to reduce traffic congestion and provide its inhabitants with sustainable public transport.

Versatile solutions for a versatile metro line

Singapore’s Downtown Line brings automation and versatility that fits the nature of the growing transport hub. Our comprehensive solutions are an essential part of the line. Why? Take a look to discover how our technology helped making the system so efficient and high performing.

Leading Singapore's public transport into the future with digital solutions

For the Downtown Line we supported our customer the Land Transport Authority (LTA) with signaling, a simulation center for signaling, electrification, the Rail Enterprise Asset Management System (REAMS) as well as an integrated depot that is unique in the world. All our solutions work seamlessly together to create a state-of-the-art, reliable transport system.

The solutions in detail

Advanced solutions to move public transport forward in Singapore.

Signaling

At the core of the fully automated signaling system of Downtown Line Singapore is the automated train protection and operation system Trainguard Sirius CBTC. It helps to shorten the intervals between trains, which improves the line’s transport capacity. In case of an unlikely incident, the CBTC system is able to continue thanks to its exclusive backup mode based on a speed codes Automated Train Protection (ATP system).

A simulation center for the Downtown Line’s signaling system enables in-depth technical analysis surrounding signal-related incidents, enhance testing of new signaling features and system functionalities before deployment as well as increase capabilities for training LTA and the operator’s technical staff.

Simulation center for signaling

A simulation center for the Downtown Line’s (DTL) signaling system enables in-depth and faster technical analysis surrounding signal-related incidents, enhance testing of new signaling features and system functionalities before deployment as well as increase capabilities for training LTA and the operator’s technical staff. The test center helps to increase the robustness of testing works and minimises disruption to passenger service.

The Downtown Line's efficient and resilient power supply system ensures both high performance and safe operation.

Electrification

The Downtown Line (DTL) power supply system is designed for optimum energy efficiency and system performance. The high level of safety of the DTL traction system is ensured by the Emergency Traction Tripping System (ETTS), which provides safe isolation of power supply in the event of emergencies, as well as the Fault Identification System (FIS) and the Stray Current Monitoring System (SMS). Apart from this, associated auxiliary systems such as a redundant battery charging system is provided. Each station is also equipped with a station control panel that allows easy interface with the SCADA system and local monitoring of events.

The digital asset management for rail systems in Singapore (REAMS) integrates asset information and maintenance records across the entire rail system.

Rail Enterprise Asset Management System (REAMS)

The digital asset management for rail systems in Singapore (REAMS) integrates asset information and maintenance records across the entire rail system, so that the health of the various operating assets can be monitored holistically over their respective life cycles. REAMS is also equipped with data analytics capabilities to monitor asset performance and identify potential risks before they occur, so that assets can be repaired or renewed pre-emptively.

In addition to the full range of services for the Downtown Line, Siemens supplies all depot equipment.

Depot equipment

In addition to the full range of services for the Downtown Line, we supply the depot equipment for the upcoming East Coast Integrated Depot. The depot will serve the East West Line (EWL), Downtown Line (DTL) and the Thomson-East Coast Line (TEL) and is the first depot of its kind to integrate three train depots and a bus depot on a single site. Comprehensive integrated and digital solutions for the depot increase the metro line’s availability and reliability.
