Lion is the longest and the most capacious three-section low-floor tram-car, with two cabins and doors on the right and left side, which allows operating without revolving rings. The new vehicle is based on the unique low-floor elastic bogie of own development and manufacture. Special attention is paid to passenger comfort:  a lot of convenient seats, separate climate control of the cabin and the driver's compartment, information screens are designed in the trams. The active and passive security system, passenger getting on/off video monitoring system  and traffic monitoring system are designed for the driver's convenience. Independent motion reserve is at least 1.5 km. The tram's bright, modern and elegant design matches the mega-city architecture and the unique historical buildings of the cities perfectly.
