Going the distance: A new energy-storage system will allow trams to travel distances of up to 2,500m without using overhead cables

摘要

TRAMS could run without overhead contact lines and emit significantly less CO{sub}2 using a new hybrid energy-storage system. Siemens, the developer of the Sitras HES hybrid energy-storage system, claims trams equipped with these systems consume up to 30 per cent less energy per year and produce up to 80 metric tons fewer CO{sub}2 emissions than vehicles without them. According to Michael Meinert, the development manager at Siemens responsible for the new system, trams with hybrid energy-storage systems can operate without an overhead contact line over distances of up to 2,500m. This, he claims, enhances the appearance of the urban landscape and is environmentally friendly.
