Summarize：The Zurich Public Transport (VBZ) has ordered twelve Ligh Tram 24-metre double-articulated trolleybuses from Vossloh Kiepe GmbH and Hess AG,which are completely emission-free. The electric drive developed by Vossloh Kiepe facilitates this by using a modern Li-ion battery as a substitute for the usual diesel generator aggregate. By combining overhead-wire operation and energy storage via Li traction batteries, the buses run without using any fossil combustibles. Thus the Ligh Trams are sustainable and environmentally friendly as well as ultra-silent.

Thus the Ligh Trams are sustainable and environmentally friendly as well as ultra-silent.
The batteries are charged while the vehicles are in operation using the overhead wire. The vehicles are designed according to Zurich's special requirements and can thus be operated over stretches as far as 1.5 km without the need for power supply from overhead wires. This also facilitates exhaust-free and low-noise manoeuvring and parking in the bus depot. The performance electronics are supported by a high-power battery chargers which are also able to charge the batteries with energy released during braking. It is integrated in the roof-mounted equipment enclosure and can recharge the traction battery within one complete line cycle. Delivery of the new 24-metre vehicles to the VBZ will begin as early as autumn of 2012.
