Krakow tests supercapacitor tram

MPK Kraków started test running of a Solaris Tramino 100% low-floor tram on February 23. The vehicle will operate for three months on Route 1 of the standard gauge network, which links Nowa Huta and the city centre.

Powered by four 105 kW asynchronous traction motors, the tram is fitted with supercapacitors to store regenerated braking energy. According to Solaris, this can result in an energy saving of 20% to 30% compared to conventional trams. The supercapacitors can also be configured to allow partly automated operation.
