The Solaris Tramino for Braunschweiger Verkehrs-AG are uni-directional low-floor vehicles, consisting of four body sections at an overall length of 35.7 metres. They are 2.3 metre wide. Each vehicle section has its own bogie for Brunswick’s track gauge of 1,100 mm.
Each air-conditioned tram for Braunschweig has a capacity of 211 passengers, including 87 seated. There are six sets of double doors, each 1,300 mm wide. One of them is located right behind the driver’s cab, where there is also the wheelchair space. The space for prams is located by the fourth and sixth doors.
Every section rests on one centrally-mounted bogie. Consequently, the weight of the tram is evenly distributed. The vehicle is more stable and the forces transmitted through the articulations are much smaller. They are the second batch of trams from Solaris’s GTx family.
The Tramino Braunschweig is equipped with five 90 kW asynchronous traction motors and supercapacitors, where recuperated energy is stored. The energy is then reused when starting tram’s operation. The vehicle is also fitted with a system which stabilises its body.
