Siemens-equipped driverless underground metro line in Singapore starts operations

11.02.2014
The public transport operator SBS Transit Limited has started passenger service on the driverless Downtown Line 1 (DTL1) in Singapore.

The commissioning of the Line, which has a total length of 42 kilometers and comprises 34 stations, will occur in three phases. Initially, service has commenced for DTL1; a section of four kilometers, with six stations and six trains in revenue operation Siemens supplies the signaling system as well as the traction power supply for all three sections of the Line. The double-track metro line is designed to transport up to 500,000 passengers per day when the Line is completed in 2017.

The current metro network in Singapore is about 180 kilometers long and is used by some 2.5 million commuters every day. The Downtown Line connects the residential areas in the northwest and east to Singapore's city center. The first section of the line that has now opened in the city center runs from the financial district to the Chinatown shopping district.

The second section, which comprises around 16 kilometers of track and twelve stations, will link the northwestern districts of Singapore to the central business district in 2016. The 21 kilometer connection of the eastern part is scheduled for completion in 2017.

Siemens supplied the automatic train control system Trainguard Sirius CBTC that uses Communication Based Train Control technology to permit driverless operation and Trackguard Westrace MK2 electronic interlockings of latest generation. The operations control system Controlguide Rail 9000 (ATS – Automatic Train Supervision) is used for automatic train monitoring. Siemens also installed the trackside and onboard equipment for fully automated train operation in unattended mode.

For the electrification of the entire line, Siemens equipped the traction power supply system for 750 VDC. Power is supplied from the 66 kV AC utility network and stepped down to 22kV AC to feed a medium-voltage ring that supplies to the traction substations, the stations and the depot with 22 kV AC using Siemens 8DA10 Switchgears. The traction substations are converts the 22 kV AC into 750 VDC using Sitras REC and distributes the electrical energy to the third rail through Sitras DSG Switchgear. The electrical energy recovered during the braking of the trains is fed back into the medium-voltage power system via Sitras TCI Inverters and thus made available to all other electrical loads.

To keep pace with Singapore's growing transport needs, the government announced in 2008 that it would be investing about 28 billion US dollars in expanding the railway network to a total track length of 360 kilometers as part of the "Master Plan 2030" program.

Im Focus: Lasers are the key to mastering challenges in lightweight construction

Many joining and cutting processes are possible only with lasers. New technologies make it possible to manufacture metal components with hollow structures that are significantly lighter and yet just as stable as solid components. In addition, lasers can be used to combine various lightweight construction materials and steels with each other. The Fraunhofer Institute for Laser Technology ILT in Aachen is presenting a range of such solutions at the LASER World of Photonics trade fair from June 22 to 25, 2015 in Munich, Germany, (Hall A3, Stand 121).

Lightweight construction materials are popular: aluminum is used in the bodywork of cars, for example, and aircraft fuselages already consist in large part of...

Im Focus: Solid-state photonics goes extreme ultraviolet

Using ultrashort laser pulses, scientists in Max Planck Institute of Quantum Optics have demonstrated the emission of extreme ultraviolet radiation from thin dielectric films and have investigated the underlying mechanisms.

In 1961, only shortly after the invention of the first laser, scientists exposed silicon dioxide crystals (also known as quartz) to an intense ruby laser to...

Im Focus: Advance in regenerative medicine

The only professorship in Germany to date, one master's programme, one laboratory with worldwide unique equipment and the corresponding research results: The University of Würzburg is leading in the field of biofabrication.

Paul Dalton is presently the only professor of biofabrication in Germany. About a year ago, the Australian researcher relocated to the Würzburg department for...

Im Focus: Basel Physicists Develop Efficient Method of Signal Transmission from Nanocomponents

Physicists have developed an innovative method that could enable the efficient use of nanocomponents in electronic circuits. To achieve this, they have developed a layout in which a nanocomponent is connected to two electrical conductors, which uncouple the electrical signal in a highly efficient manner. The scientists at the Department of Physics and the Swiss Nanoscience Institute at the University of Basel have published their results in the scientific journal “Nature Communications” together with their colleagues from ETH Zurich.

Electronic components are becoming smaller and smaller. Components measuring just a few nanometers – the size of around ten atoms – are already being produced...
