passengers for the first time in Armenia's history. A second airport, Erebuni Airport, is located just south of the city. Since the independence, "Erebuni" is mainly used for military or private flights. The Armenian Air Force has equally installed its base there and there are several MiG-29s stationed on Erebuni's tarmac. City buses, public vans and trolleybus Public transport in Yerevan is heavily privatized and mostly handled by around 60 private operators. As of May 2017, 39 city bus lines are being operated throughout Yerevan. These lines mostly consist of about 425 Bogdan, Higer City Bus and Hyundai County buses. However, the market share these buses in public transit is only about 39.1%. But the 50.4% of public transit is still served by "public vans", locally known as marshrutka. These are about 1210 Russian-made GAZelle vans with 13 seats, that operate same way as buses, having 79 different lines with certain routes and same stops. According to Yerevan Municipality office, in future, marshrutkas should be replaced by ordinary larger buses. Despite having about 13 seats, the limit of passengers is not controlled, so usually these vans carry many more people who stand inside. The Yerevan trolleybus system has been operating since 1949. Some old Soviet-era trolleybuses have been replaced with comparably new ones. As of May 2017, only 5 trolleybus lines are in operation (2.6% share), with around 45 units in service. The trolleybus system is owned and operated by the municipality. The tram network that operated in Yerevan since 1906 was decommissioned in January 2004. Its operation had a cost 2.4 times higher than the generated profits, which pushed the municipality to shut down the network, despite a last-ditch effort to save it towards the end of 2003. Since the closure, the rails have been dismantled and sold. Due to being dispersed among dozens of private operators, the transportation is barely regulated, with only trip fee is being a subject of regulation. Thus, the quality of vehicles is often inadequate, with no certain regulations for safety. Unlike the majority of world capitals, there is no established ticketing system in Yerevan's public transportation. Passengers need to pay the money directly to the driver when getting out of the vehicle. The fare -being one of the few things that is regulated- is fixed and controlled by authorities. The central station in Nor Kilikia neighborhood serves as bus terminal for inter-city transport,
