Leading traffic technology company 189 Siemens has unveiled a new generation of signal heads specifically designed and built for tram operations. Based on the company’s existing range of Helios extra low voltage (ELV) traffic signals, the dedicated ELV tram signal is fully compatible with the company’s ST900 ELV controller. According to head of product management, Keith Manston, the Siemens ELV solution is priced lower than currently available low-voltage tram signals and all aspects can be lamp monitored as normal ELV LED signals.
