The Sofia trolleybus system (Bulgarian: Тролейбусен транспорт София) forms part of the public transport network of Sofia, the capital city of Bulgaria.

In operation since 14 February 1941, the system presently comprises nine routes with 257 km network build, of which 193 km are currently in use.

As of 2010 the average speed of the trolleybus system in Sofia is 14,4 km/h.


Trolleybus transport was the last form of surface public transport to develop in Sofia, after buses and trams. The first Sofia trolleybus line opened on 14 February 1941. It was over 3 km (2 mi) long, and connected the city with the Gorna Banya quarter.[1]The line was covered by 2 MAN 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.[1]

In 1987, a new depot, "Iskar", was opened with a capacity of 130 trolleybuses.[1] Levski depot was opened in 1994 with capacity of 60 trolleybuses. As of 2015 two depots are in operation: Nadezhda and Iskar. Levski depot operates as a maintenance only facility.


As of January 2016, the following trolleybus lines in Sofia are in service:
