Our trams can operate on sections of routes with no overhead wires, such as historic city centres, and offer range increase of up to 5km. It''s flexible too. The new technology is based on an Onboard Energy Storage System (OBESS), with scalable battery capacity. It can be installed directly on the roof of existing trams - saving on costs all ...
Now, another milestone in the development of these wire-less systems has taken place. On 1 October 2015, Bombardier successfully completed a 41.6 km catenary-free test run with a tram powered entirely by its Primove battery in combination with a Mitrac propulsion system. The test run was conducted in the German city of …
