History
editTrolleybus transport was the last form of surface public transport to develop in Sofia, afterbuses andtrams. The first Sofia trolleybus line opened on 8 February 1941. It was over 3 km (2 mi) long, and connected the city with the Gorna Banya quarter.[2] The line was covered by 2MAN trolleybuses, which were stored on the last stops during the night, due to the lack of depot.
In the 1950s and 1960s, massive development of the trolleybus transport in Sofia began. At that time, the construction of new trolleybus routes proceeded especially rapidly, and two depots ("Stochna Gara" and "Nadezhda") were opened, with a total capacity of 160 trolleybuses. In 1951, the first Bulgarian made trolleybuses entered service.[2]
In 1987, a new depot, "Iskar", was opened with a capacity of 130 trolleybuses.[2] Levski depot was opened in 1994 with capacity of 60 trolleybuses. As of 2021 three depots are in operation: Nadezhda, Iskar and Levski. The latter also serves as a storage and overhaul facility.
