The subject of the project is the construction of a new converter station in the former MR 1 station in order to improve the supply conditions of the lines in the centre of Pardubice. The establishment of the substation will allow the further development of trolleybus transport in the city centre (increasing the number of connections). The related arrangement of the individual power sections will then allow the supply of a short branch trolleybus line to the university campus in the vicinity of Studentská Street, without having to establish a special power supply for this line.
