The applicant will put 4 new so-called partial trolleybuses into operation. That is, trolleybuses with an energy accumulator allowing driving in sections outside the overhead contact line. The wagons have a combined power supply – for parts of the route directly from the two-pole overhead contact line and to the part of the route from the traction power accumulator, recharged from the overhead contact line. This will enable the public transport operation in electric traction to be extended to selected places where the overhead contact line is not built.
