The tram is equipped with batteries in case of a power outage, giving it an additional distance at low speed without an external electric source. The vehicle also has a modern passenger notification system, video surveillance, air conditioning and other similar equipment which is housed on the roof together with the pantograph, conductor, transducer and resistors. It has a capacity of 130 people.
As with the previous 2200 model, the bogie is designed as to store wheels in the bearing boxes that form the basic frame. The basic frame is then stored in the chassis frame itself, and the axle is replaced by a shaft. Secondary and primary suspension is solved by hydropneumatic springs. The engines are mounted longitudinally.
