History

Planned since the 1960s, construction of the metro started in the 80s with the demolition of a significant number of buildings. At the beginning of the 90s, construction stopped due to a lack of funds and the complexity of the construction work. Being one of the oldest cities in Europe, Sofia contains many historical layers underneath its central areas. Evidence of antiquity can be clearly seen at the Serdika Station, which exhibits a wealth of unearthed Thracian and Roman ruins. During the construction of the enormous complex of the National Palace of Culture, two stations forming part of the M2 line and their connecting tunnels were built.

The construction of the system began from the route that sees the highest volume of passenger traffic, reaching 38,000 at rush hour.^[10]

Lines

Due to an increased population, there are a large number of passengers heading toward the city center during weekday mornings, and away from the city centre in the weekday evenings. The necessity of efficient public transport in the direction of the largest passenger flows, transport, and Sofia's environmental problems precipitated the start of the construction of the Sofia Metro. Following the ratification of a technical and economic report on the metro by the Council of Ministers of Bulgaria, and the subsequently approved General City Plan, the general scheme for the development of the lines should consist of three diameters with extensions in the periphery, with a total length of 72.5 kilometres (45.0 mi), 75 metro stations, and a 1.1 million daily passenger capacity at the final stage of implementation.^[11]

Security and safety

There are automatic gates installed on the platform due to safety reasons. This is one of the key features in the new metro line from 2020. The gates open automatically when a train approaches and they close 5-10 seconds before the train starts. There are CCTV cameras and sensors which make sure the metro line is clear, so accidents don't happen. There are more than 10, 000 cameras in all of the metro stations in Sofia. The metro is guarded by security guards who stop suspicious people or people with illegal or harmful items.

The first 6.5 kilometres (4.0 mi) long section of M1 line consisting of five stations linking Slivnitsa Boulevard through Lyulin and K. Velichkov Boulevard was inaugurated on 28 January 1998. Opalchenska station entered into service on 17 September 1999 and Serdika station situated on St Nedelya Square followed on 31 October 2000, extending the total system length to 8.1 kilometres (5.0 mi). The operational section of the line was further extended with a 1.8 kilometres (1.1 mi) long section, reaching Obelya housing estate in April 2003.

The extension of M1 line continued in 2005 with the start of the construction of 4.8 kilometres (3.0 mi) of tunnels and three stations linking St Nedelya Square and the Interped World Trade Center in Izgrev (station Frédéric Joliot-Curie). 2006 saw the start of the construction of another section of the same line (consisting of 3.2 kilometres (2.0 mi) of tunnels and three stations) linking Izgrev and Mladost I housing estate. The completion of the first three stations was projected for the autumn of 2007, however as a result of various delays it was the second section from the first line (Vasil Levski stadium – Mladost 1) that first entered into service on 8 May 2009, operating for a brief period of time separately from the north-west portion of the line. The remaining section between Serdika and Vasil Levski stadium station finally entered into service on 7 September 2009^[12] establishing an uninterrupted link between Obelya and Mladost 1 stations.

The construction of the section from Mladost I to Business Park Sofia station (2.62 kilometres (1.63 mi), with three new underground stations) began on 25 April 2013, and was completed on 8 May 2015.^[7][13] It cost BGN 85,767,683 (EUR 43,852,320), VAT exclusive, and serves the majority of the second most densely populated area in Sofia.^[14][15] Part of the sections of "Sofia Airport" - "Iskarsko Shose" and, Ovcha kupel" -, Krasno selo" are not underground.

The second and fourth lines of the Sofia Metro links the districts of Obelya, Nadezhda, the city centre and Lozenets to the south of the city.^[17] Half of the construction cost was covered by the European Union, with the remaining part funded by the state and city budgets.^[17] Construction of the 6.4 km (4.0 mi) section between Nadezhda interchange and Lozenets district via Central railway station and the National Palace of Culture started on 14 December 2008. Work on the section between Obelya residential District and Nadezhda started in February 2010. Both sections of the line entered into service on 31 August 2012.^[17]

NDK and European Union stations and their connecting tunnels were partly completed during the construction of the National Palace of Culture and the redevelopment of the surrounding area in the late 1970s and early 1980s.

The construction of Mladost 3 and Inter Expo Center – Tsarigradsko shose stations began on 15 February 2009 and was completed on 25 April 2012. The further extension to Sofia Airport comprising two underground and two overground stations and a length of 4.968 kilometres (3.087 mi) began in 2013,^{[13][18][19][20]} and was completed on 2 April 2015 at the cost of BGN 136,757,630 (EUR 69,923,066), VAT exclusive.^[8][9] This extension was briefly operated as a branch of M1 line, but was soon^[when?] transferred to M2 line, moving that line's terminus from Obelya to Sofia Airport.

On 20 July 2016, the line was extended southward with 1.3 km (0.81 mi) and one station, Vitosha, located at Hladilnika neighbourhood.^[2] The construction took 2 years.

Provisions have been made for the construction of future branch to Iliyantsi, starting from the existing junction located between Knyaginya Maria Luiza and Han Kubrat stations.

Splitting the line to M2 and M4

On 26 August 2020, the second line was split into two portions: the M2 line, running from Vitosha station to Obelya station and the M4 line, running from Obelya to Sofia Airport. The trains continue to run the length of both lines but on maps and other metro signage the M4 line is gradually being introduced. The split is in preparation to the future construction of the Pancho Vladigerov station, which is supposed to physically separate the lines and will allow them to have independent timetables.

M5 line (planned)

M5 is a planned line, servicing Studentski grad and Iliyantsi. This line would share more than half of M2's stations.

The Studentski grad branch would start from Cherni vrah Blvd, passing through Vitosha quarter and finally, enter Studentski grad. The Iliyantsi branch would start after Maria Luiza station, joining in on Iliyantsi Blvd, and have 4 stations on it.

Recently, a route has been planned for the Studentski grad branch, including 5 stations with one of them being shared with M2.

The 16 km (9.9 mi) long M3 line is planned to connect the Ovcha Kupel neighbourhood (in southwest Sofia) and the Vasil Levski neighbourhood (in northeast Sofia), with 16 stations in total, including two transfer stations in the city centre, with the rest of the already operational lines. The first 8 stations of the line entered service on 26 August 2020, and another 4 on 24 April 2021.^[22]

The original plan was to have 8 aboveground and 11 underground stations. The project design contract was awarded to the Czech company Metroprojekt Praha a.s.^[23][24][25]

In March 2014, a tender for construction of the central section of the line was announced. The section is 7 km (4.3 mi) long and includes 7 stations, two of them transfer to lines 1 and 2. With the announcement of the tender, it became clear that the initial plans for 19 stations had been partly amended and 2 of the stations, one at Doyran boulevard and another at Shipka street, will be not be built. The tunnel of the central section shall be excavated by a tunnel boring machine, while the construction of stations shall be awarded to other companies. The construction of the section shall be completed within 45 months.^[26] In January 2015, a tender for 20 trains that shall serve the central section of the line was announced. Driverless train operation, with Grade of Automation 3 (GoA 3), and platform screen doors will ensure the safety of the passengers. Unlike lines 1, 2 and 4, where the trains collect power through a third rail, line 3 trains will be equipped with pantographs.^[27][28] CAF and Siemens applied bids in the tender for the trains,^[29] with Siemens winning it.^[30]

In early 2016, construction began on the third metro line of the Sofia Metro using the technology for classic underground metro with high-power support. Under construction were all metro stations in the central section, the ones in the west and some in the central-east of downtown Sofia. The Krasno selo - Hadzhi Dimitar section opened on 26 August 2020, with the extension from Krasno selo to Gorna banya opening on 24 April 2021.

The third line of the Sofia Metro is planned to have a total of 23 metro stations, as follows: 16 metro stations for the main line and 6 metro stations for the Slatina branch.^[31][32][33] Currently, 12 stations of the main line are in operation and 3 stations in Levski are under construction, with their estimated completion being in 2025. Now, another 6 stations are starting construction in the Slatina branch.

Fares and ticketing

The price of a single ticket is 1.60 lev, equivalent to ~0.82 euro. It can be issued either by a cashier, or by a vending machine. When obtained, the single ticket must be validated within 30 minutes at a validator. Pre-paid RFID (MIFARE Classic) card also could be bought (at a price of 2 levs) with minimum 10 pre-paid rides (at a price of 12 levs for 10 pre-paid rides).

In addition, passengers will be able to pay using a mobile wallet (Apple Pay, Google Pay, Garmin Pay etc.). The fare will be the same price as a paper ticket (1.60 lev or ~0.82 euro) and the amount you pay per day will max out at 4 levs (or about 2 euro) which is 3 trips (the first and second trips will cost the full 1.60 levs, 3rd will cost 0.80 levs and every trip after will be de facto free). The 4 levs max resets every day at 12 am local time.

Rolling stock

The system uses 3 types of rolling stock.
