Light Rail Transit solutions

Offering new features and new levels of accessibility and safety at complex Light Rapid Transit (LRT) junctions, Siemens ST950 controller delivers full LRT functionality at both LV (230V) and ELV (48V) output drive levels.

The Siemens Tram Signal Head completes the LRT portfolio. Manufactured by Siemens in Poole and fully compatible with the company's ST950 controller, the new tram signal head uses energy-saving, long-life LED technology and all aspects can be lamp monitored as normal ELV LED signals. The LRT signals compliment the Helios signal head range which features Siemens' SIRA style enhanced optics and the latest LED Central Light Source (CLS) delivering optimum clarity and reliability.

Edinburgh

In Edinburgh, trams have started operating using our latest ST950 ELV controllers and ELV Tram Signals. These are not only linked to the city's traffic control facilities but also to the signal technology of the trams, in order to provide tram priority at 25 junctions on the network.

 

Working as a member of a consortium led by construction group Bilfinger, Siemens was awarded the order for what was then Scotland's largest infrastructure project in 2008. Within the consortium, Siemens was responsible for systems specific to the rail infrastructure, including signalling and control, communications and passenger information, traction current supply, catenary equipment, the depot equipment and the track system.

 

The service runs on a 10 mile urban tram route which links the airport with the city centre. Running at a frequency of better than 15 minutes, with 15 stops, the trams ply the route up to 100 times a day in bidirectional operating mode.

Dubai

The new Dubai Tram System will also feature ST950 controllers with enhanced software for LRT operation and integral outstation functionality. The project to upgrade traffic signals and interface all associated detection equipment to meet the specific requirements of the Tram Project and provide full in-territory training on installation, configuration and maintenance was secured by Siemens in association with the company's partner in Dubai, Scientechnic. Linking the Dubai Metro and the Palm Monorail, the new Dubai Tram System will form an integral part of the transport network and is expected to be ready by the end of 2014.
