The public transport in Sofia consists of a comprehensive network of bus, trolleybus, tram and metro lines. It is overseen by the Sofia Urban Mobility Center, a municipal enterprise responsible for route planning, scheduling, fare collection and ticket inspection. It also pays the various transport operators for their service on a per-kilometer basis. Sofia is the only city in Bulgaria that operates the four modes of public transport.Eurotransport magazine issue 6, 2015 ISSN 1478-8217

Rail
Plans for a regional, if not a suburban, rail system have been discussed for a while, but no official plans have been prepared. Non-government organizations, like Spasi Sofia, have announced their interest for the creation of a regional rail network.
Trolleybus
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 8 February 1941. It was over long, and connected the city with the Gorna Banya quarter. 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. In 1987, a new depot, "Iskar", was opened with a capacity of 130 trolleybuses. "Levski" depot was opened in 1994 with a 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. The system presently comprises 10 routes with 193 km route length.
Bus
The public bus transport in Sofia developed relatively late compared to the other types of transport in the city. The first operational line was opened on 20 April 1935. Soon after that six more lines were opened, bringing the total network length to 23 km.History of the bus transport in Sofia
During the communist era, the bus fleet consisted mainly of Ikarus and Bulgarian-made Chavdar buses. After the political changes in 1989, however, the fleet has gradually been modernised. The system presently comprises 98 routes with a length of 2,380 km.
