The object of the project is to acquire 27 fully barrier-free and low-floor buses (16 solo + 11 articulated) with natural gas propulsion that meets the emission standard EURO 6, which will replace diesel buses of lower emission classes EURO 2 (4 solo),EURO 3 (9 solo and 3 articulated) and EURO 4 (11 articulated buses).
