The Solaris Tramino is bi-directional. As it has two driver’s cabins, it can be used effectively on one-rail routes so there is no need to build a tram loop. The trams for Olsztyn consist of three sections. Each of them runs on a pivoting bogie of its own. Tramino Olsztyn's track has a gauge of 1,435 mm. In order to reach maximum effectiveness it uses performance wheels with a large diameter of 682 mm. However, despite the wheel dimensions the floor remains 100% low. In designing the tram, Solaris's engineers introduced a range of innovative technologies and unusual solutions that hitherto have been unknown in Poland and even in European markets. One such development is automatic levelling at different loads and wear of wheels. Four asynchronous 120 kW traction motors deliver the necessary power. The new trams are equipped with two batteries with a 540 AH capacity which allows them to operate independently of overhead wires.
