The Thessaloniki Metro (Greek: Μετρό Θεσσαλονίκης, Metró Thessaloníkis^ⓘ, [meˈtro θesaloˈnicis]) is an underground rapid-transit system under construction in Thessaloniki, Greece's second largest city. The system is fully-automated and driverless, the first system of its kind in Greece, and is operated by Thessaloniki Metro Automatic (THEMA), a Franco-Italian consortium.

Estimates for the cost of the megaproject are at €3 billion ($3.24 billion), including €600 million ($649 million) in future interest payments. The project is primarily funded with loans from the European Investment Bank (EIB) and the European Regional Development Fund (ERDF), as well as funds from the Greek government. Construction by a Greco-Italian consortium is overseen by Elliniko Metro, the Greek state-owned company which oversaw construction of the Athens Metro and Athens Tram.

Proposed during the 1910s and first seriously planned in the 1980s, construction of the main line began in 2006 and on the Kalamaria extension in 2013. The system under construction has 18 stations and 14.4 km (8.9 mi) of tunnels. After years of delays, due to archaeological discoveries and the Greek financial crisis, the main line is scheduled to open on 30 November 2024.

Ernest Hébrard and Thomas Hayton Mawson were the first to propose the creation of a metro system in Thessaloniki in 1918 as part of a commission appointed by the government of Eleftherios Venizelos to redesign the city after the Great Fire of 1917, which had devastated the city centre.^[9] They proposed an underground railway to connect the New Railway Station and a second proposed railway terminus in Nea Elvetia.^[10] Although Thessaloniki has grown considerably since Hébrard's original design, Line 1 is almost identical to his plan and runs from his proposed new railway station to the suburb of Nea Elvetia.^[11][12] The project never materialised. A circular metro line was proposed in 1968, extending to the airport and crossing the Thermaic Gulf in a tunnel.^[8]

The idea of a metro was revived during the 1980s. In 1987, the University of Thessaloniki published a proposal for an extensive, multi-branch light metro system, envisioned to be underground only between the New Railway Station and Sintrivani, at a cost of ₯12.5 billion ($92 million – $248 million in 2023) for the underground portion.^[13] In 1988, under Mayor Sotiris Kouvelas, the city published studies for its Thessaloniki Metro development plan and construction of the project's first phase.^[14] The line was almost identical to the modern line, with 14 stations between the New Railway Station and Nea Elvetia. The plan had one additional station, Patrikiou, between 25 Martiou and Voulgari and had alternative names for three stations. Dimokratias is shown as Vardari, an alternative name for the public square served by the station; Venizelou is listed as Alkazar (Hamza Bey Mosque, on the corner of Egnatia and Venizelou Streets), and Efkleidis is shown as Archaeological Museum.^[14] The network would be within the city limits, excluding Kalamaria and a large portion of Thessaloniki's metropolitan area. Of the 7.77 km (4.83 mi) of track proposed, 6.26 km (3.89 mi) would be underground and 1.51 km (0.94 mi) above ground.^[14]

In 1989, construction began on the first 650 metres (2,130 ft) of tunnel along Egnatia street between the Thessaloniki International Fair grounds and Aristotle University of Thessaloniki (the present Panepistimio station).^[14] Construction was carried out with the cut-and-cover method instead of a tunnel boring machine. The proposed metro was only 4.5 metres (15 ft) beneath ground level at 25 Martiou but dropped to about 10 metres (33 ft) towards the New Railway Station, creating archaeological problems similar to those encountered during construction of the current system. Although construction was scheduled to end in 1995, the project stalled and the unfinished (but excavated) initial cut-and-cover section became known as "the hole of Kouvelas" (Greek: η τρύπα του Κούβελα, i trypa tou Kouvela).^[14] The project ultimately failed due to a series of unsuccessful contract competitions and appeals of awarded contracts. Another obstacle was lack of interest by Greece's central government. Thessaloniki attempted to fund the project on its own, saying that European Union member states were prepared to cover 50 percent of the project costs and provide favourable loans for the remainder, but without the central-government's involvement the plan did not go forward.^[14] One reason for the lack of central-government support was Greece's political polarisation during the 1980s; Kouvelas represented the centre-right New Democracy party when the country was governed by the Panhellenic Socialist Movement. Plans for a Thessaloniki metro were abandoned until the 2000s.^[11]

In 2018, Elliniko Metro S.A. was overseeing the construction of a two-line, twin-tunnel system composed of Line 1 (the base project) and Line 2 (the Kalamaria Extension). Although Line 1 has been delayed by extensive archaeological works, Line 2's construction is proceeding on schedule.^[11] Construction of tunnels for both lines was finished in 2018, and track-laying began in August of that year.^[15] Line 1 and Line 2 were expected to be operational by December 2023.^[16] Both lines are designed to serve a minimum of 18,000 passengers per hour in each direction, with a 90-second headway.^[2][17] The completed metro will reduce Thessaloniki's greenhouse gas emissions by an estimated 5,000 tons a year, and reduce travel time by up to 66 percent.^[18]

What is known as the Base Project (Greek: Βασικό Έργο) began in 2003, when Attiko Metro and the Greek government agreed to cooperate on a public works project^[3] Government support was instrumental, since lack of government support for the 1988 proposal was the primary reason it had failed. The project issued a request for tender in 2004–2005, and the successful Greco-Italian consortium (which included AnsaldoBreda) began construction in late June 2006.^[3] An alternate consortium, Macedonian Metro (Greek: Μακεδονικό Μετρό), was barred by the European Court of Justice from participating in the tender because it changed its composition after the tender proceedings began (violating EU law).^[19] The project was budgeted at €1.05 billion ($1.19 billion), with 25 percent funding from the Greek government and 75 percent funded by loans from the European Investment Bank and the European Regional Development Fund.^[20] The latest available Attiko Metro financial data put the official estimated cost at €1.28 billion ($1.45 billion).^[21] An April 2019 update raised the estimated cost to €1.62 billion ($1.83 billion).^[22] Line 1 runs within the municipality of Thessaloniki, the core of the Thessaloniki urban area, calling at 13 stations.

It has two parallel single-track tunnels on a 9.5 km (5.9 mi) route between New Railway Station (for the city's main railway station) and Nea Elvetia, with Pylaia depot further southeast. Although construction began in 2006, major archaeological finds in the city centre delayed the project considerably. Disputes between Attiko Metro, the city council, and archaeologists reached Greece's Council of State, the country's highest administrative court, in 2015.^[11] The original schedule had Line 1 operational by 2012.^[11] Attiko Metro redesigned several stations in a solution which became known as "antiquities and metro" (Greek: και αρχαία και μετρό).^[23] Some finds discovered on the line will be put on display at permanent in-station exhibitions, while the major discoveries at Venizelou will make up the world's first publicly-accessible open-air archaeological site contained in situ within a metro station.^[23]

Construction of the tunnels was completed on 31 July 2018, 12 years and one month after breaking ground.^[24] That day, the architectural work on Line 1 was reported as 80 percent finished.^[24] In August 2018 installation of the tracks and electronic signalling equipment began.^[15] It was expected that the line would enter service in its entirety, between New Railway Station and Nea Elvetia, in 2020 but will not stop at Agias Sofias and Venizelou, which will open at a later date.^[25][26] By February 2019 construction on the main line was 95 percent completed and platform screen doors were beginning to be installed, while the Supreme Council for Civil Personnel Selection was planning a competition to fill the first 28 Thessaloniki Metro employee positions.^[27]

Despite the progress, in September 2019 Greece's new conservative cabinet announced a further 28-month delay to the project, pushing the opening date from November 2020 to April 2023 and citing costly archaeological works at Venizelou as the reason.^[28] The new Minister of Infrastructure and Transport announced that the government had decided to scrap the previous plan to keep the archaeological discoveries in situ within the station at Venizelou, choosing instead to disassemble them and re-assemble them at a later stage, noting that excavation costs had exceeded €130 million ($146.86 million), more than the cost of the new Acropolis Museum.^[29] Thessaloniki's new conservative mayor, Konstantinos Zervas, as well as Prime Minister Kyriakos Mitsotakis, supported this move. Mitsotakis also announced at the Thessaloniki International Fair that a new archaeological museum would be built specifically to house archaeological artefacts unearthed during the construction of the metro. The new head of Attiko Metro (now Elliniko Metro) accused archaeologists of "looking to the past; we need to look forward".^[30] There were two more delays, one from April 2023 to December 2023, and one from December 2023 to March 2024.

The decision to disassemble the archaeological finds, dubbed a "Byzantine Pompeii",^[31][32] was strongly criticised, and a citizens' group has taken the government to court over the issue for a second time, supported by former mayor Yiannis Boutaris among others.^[33] Part of the objection has to do with the fact that the government has not carried out any studies as to how it will return and re-assemble the artefacts once the station has been built;^[33] this course of action was adopted for the construction of Agias Sofias metro station, where the archaeological discoveries were more significant than those at Venizelou, but the re-assembly of the artefacts on site is now impossible because Attiko Metro never constructed any space dedicated to the re-assembly of the artefacts it disassembled, despite having promised to do so.^[34] In April 2020, the International Association of Byzantine Studies (AIEB) wrote to Prime Minister Mitsotakis to protest the removal of the antiquities from their original location, saying that the discoveries constituted "a cultural and scientific jewel" and that "it would be a tragedy to jeopardise [Greece's reputation for monument preservation] by squandering the treasure of the Thessaloniki material and data through an unnecessarily hasty construction project", arguing that the previous decision to leave the discoveries in-situ was preferable.^[32]

A final opening date for Line 1 was set for noon on 30 November 2024.^{[35][36][37][38]} In preparation for this, a brand identity was unveiled on 13 November 2024,^[39] while the final project cost of €3 billion ($3.24 billion), including €600 million ($649 million) in future interest payments, was revealed on 20 November 2024.^[38]

The Kalamaria Extension (Greek: Επέκταση Καλαμαριάς) extends the metro system to Kalamaria, the second-largest municipality in the Thessaloniki urban area and the 18th-most-populous in Greece. Similar in construction to Line 1, it has two parallel single-track tunnels on a 4.78 km (2.97 mi) route between 25 Martiou and Mikra and adds five stations to the network.^[3] Construction on the project began in 2013, with a budget of €518 million ($585.18 million).^[20][3] By 31 July 2018, the extension was 60 percent completed.^[24] Although construction began seven years after Line 1, it is expected to fully enter service just six months after Line 1, in May 2025.^[16][40] This is due to the lack of major archaeological works, enabling the project to proceed without delays.^[11] The latest Elliniko Metro financial statement puts the extension's cost at €568 million ($642 million).^[21] An April 2019 update raised the estimated cost to €640 million ($723.01 million).^[22] The line is made up of 16 stations, 11 of which are also stations served by Line 1.

After confusion about the extension's place in the system, Elliniko Metro clarified in August 2018 that it would be a separate line running between New Railway Station and Mikra without the need to change trains at 25 Martiou.^[40] The extension of Line 2 to Makedonia Airport went to tender in March 2019 with an initial budget of €254,150 ($287,000) for topographical works in order to enable more detailed planning of the line.^[41]

The extension to the northwestern districts initially included a circular line and was in a preliminary phase^[42][43][44] until the fall of 2023 when the management of Elliniko Metro S.A. decided not to proceed with the project, considering it both structurally unfeasible and wrong in design. The project now includes a northwest extension of Line 1 that will start from Dimokratias, will cross Stavroupoli and Evosmos, will reach the hospitals at the northwestern entrance of the city, and will end at a second depot of Line 1 situated at the ring road of Thessaloniki. The relevant decisions were announced by Hellenic Metro S.A. on May 20, 2024. The funding process will begin in 2024.^[45][46]

The contractor's audit procedures will follow, along with the approval by the Court of Audit and the signing of the contract with the contractor. The northwestern extension will be a priority among all future extensions of the Thessaloniki Metro and will include the following stations:

• Dimokratias (existing station)
• Neapoli (Roumanikon Park, Neapoli)
• Terpsithea
• Stavroupoli (Lagada and Lykourgou, Thessaloniki Psychiatric Hospital)
• Polichni (former name Agia Varvara, Davaki Street, S.O.A., Paul Mela Camp^[47] or with alternative positioning of Lagadas and Davakis^[48])
• Efkarpia
• Papageorgiou Hospital

The tender for the northwestern extension is expected to be completed by 2027.^[49]

Topographic works, geological and geotechnical studies are currently being tendered for the project.^[42] This extension will start from Mikra and will continue to the south, with an underground part from Mikra to ASP (Higher School of War), an overground part to Georgikis Scholi Avenue and another overground part from IKEA to the airport.^[50] The overground parts of the line will probably stand at a height of 5 meters and on a bridge in order to avoid further delays due to possible archaeological finds. Tendering for the main project will take place in late 2024.^[51]

The stations of the extension will be:

• Higher School of War (old name Marinou Antipa,^[52] on Georgikis School Street), near Vrochidis and PAOK Sports Arena^[53][54]
• Patriarchiko
• Interbalkan Medical Center (former names IKEA, "Green Lanterns" and "Shopping Centers", at the junction of Agricultural School and Asklipio, new stadium Aris, OASTH bus station)^[55]
• Agricultural School (old names of the station Agricultural School, Agricultural School and Kombos Thermi, Green Traffic Lights, junction of G. School and EO Thes/kis-Polygyrou)^{[56][57][circular reference]}
• Makedonia Airport
• Center for Innovation & Technology

Line 1 will be extended further to Thermi from Patriarchiko, with only one station currently planned.

• Thermi

On May 20, 2024, projected Line 2 was officially announced, as connection of the western with the northeastern districts of the city has been deemed necessary. Line 2 will run under Tsimiski avenue and parallel to Line 1, which will eventually meet at University station. However, from that station, it will head northeast.

The stations of Line 2 will be:

• Ano Evosmos
• Perifereiaki
• Evosmos
• Menemeni
• Ampelokipi
• New Railway Station (adjacent station with Line 1)
• Dimokratias (adjacent station with Line 1)
• Aristotelous Square
• H.A.N.Th.
• University (adjacent station with Line 1)
• Agios Dimitrios
• Toumba
• Charilaou
• Agia Kyriaki

Line 2 is further projected to include extensions to KTEL Macedonia and Kordelio. Breaking from the Ampelokipi station, this extension will include the following stations:

• Ampelokipi
• KTEL Macedonia
• Eptanisou
• Kordelio

The Thessaloniki Metro will be of GoA4 category,^[58] the first of its kind in Greece, as starting, stopping, and the operation of doors will be fully automated without any on train staff.

All 18 stations currently under construction were designed with platform screen doors for maximum protection, while the trains will be driverless.^[2] Eighteen Hitachi Rail Italy Driverless Metro units will be in service on Line 1, and 15 on Line 2.^[2] The articulated, four-car trains will be 50 metres (160 ft) long.^[59] They will have seating for 96 passengers and standing room for 370 more.^[59] The trains will use 750 V DC third rail electrification, while tracks have been laid to the standard gauge of 1,435 mm (4 ft 8+1⁄2 in).^[2] A carriage was on display at the September 2018 Thessaloniki International Fair before trial runs in 2019.^[60] As of August 2019 two complete train sets have been delivered to the depot, with an additional train set expected every 2 to 3 months.^[61] The system's level of automation has prompted Attiko Metro to call it "the most modern metro in Europe".^[3]

A 50,000 m² (540,000 sq ft) depot is under construction with the intention of serving both lines, with a total built-up area of 120,000 m² (1,300,000 sq ft) and a total cost of €130.5 million ($147.43 million).^[3][62] Apart from being the system's automated remote control command centre, the complex will also house the offices of Elliniko Metro, the Thessaloniki Transport Authority (TheTA), and the Thessaloniki Metro operating company, as well as railway stock maintenance facilities, two restaurants, and a crèche.^[63][64] It is expected that the development of the depot will attract investment to the area, and there have been calls to make provisions for a passenger station at the depot.^[63] The depot complex is expected to be finished in May 2019.^[64]

As part of the initial design, 3,700 park and ride parking spaces were created – 1,050 spaces at New Railway Station, 650 spaces Nea Elvetia, and a further 2,000 at Panepistimio, the system's halfway point serving Greece's largest university.^[3] Additional parking will be created at Mikra, the terminus of Line 2.^[65]

Elliniko Metro conducted a 2005 survey to determine Thessaloniki residents' preferred fare for the metro compared to the standard price of a Thessaloniki Urban Transport Organization (OASTH) bus ticket (€0.50 at the time). Of the 400 respondents, 47.6 percent said that they were willing to pay the same price and 48.1 percent said they would pay more. Of the latter, 19.9 percent said that they would pay €0.60; 19.6 percent would pay €0.70, and 8.6 percent would be willing to pay €1.00 (double the cost of a bus ticket).^[66] The remaining 4.7 percent responded with another fare. A standard 2023 single-trip OASTH bus ticket is €0.90, or €0.45 with a discount.^[67]

Thessaloniki Metro will utilise an electronic card ticketing system as well as fare gates,^[68] a system not originally implemented on the Athens Metro. In October 2024 it was reported that there was concern the ticketing system might not be ready on time for the opening on 30 November, due to the Thessaloniki Transport Authority not initiating the procurement process on time.^[69] The company attempted to bypass procurement requirements claiming extraordinary circumstances but the Court of Audit ruled this illegal, saying that the opening date of the metro was not an extraordinary circumstance, and that the size of the order (2.7 million paper tickets and 100,000 plastic cards) necessitated a public invitation to tender.^[69]

In November 2024 it was announced that a typical ticket will cost €0.90, but the cost will be reduced to €0.60 for the first six months of the system's operations.^[70] A monthly ticket will cost €16, compared to €27 for a monthly bus pass for the city's bus network.^[70]

Variations of the letter μ in Greek manuscripts

The system logo

In preparation for the start of operations on 30 November 2024, Minister of Infrastructure and Transport Christos Staikouras revealed the system's brand identity.^[39] The central design element is lowercase Greek letter M (μ), in the Greek miniscule style used to write Medieval Greek manuscripts, in reference to the city's Byzantine history.^[71] Dark blue was chosen as the main brand colour, to symbolise stability.^[71] The SIL Open Font Commissioner was chosen for the word 'metro' in the logo, and for promotional materials and signage.^[71]

The logo attracted criticism both for its cost and its aesthetics, the latter particularly on social media due to its simpicity.^[72][73][74] Elliniko Metro initiated two design competitions, with an initial prize of €8,000 ($8,650), but both were cancelled and the contract was instead awarded directly to a company for €30,000 ($32,438).^[72] The company retorted that the second competition was cancelled due to not being satisfied with the bids received (8 in total), eventually deciding to award the €30,000 prize money to a company directly in order for the visual identity to be ready on time,^[75] while the Architects' Association of Thessaloniki accused the company of deliberately orchestrating the situation in order to give the contract to an "obscure start-up which did not even have a website at the time of its appointment",^[76] a situation it described as "a sham process - at the expense of fellow architects and other related professionals (graphic designers, artists) and ultimately the local community" as part of a "long list of direct appointments".^[76] The spokesman of the Government of Greece described concerns around the brand's aesthetics as "legitimate", but otherwise defended both the design and the companies involved.^[77]

In an examination of the metadata on the official branding presentation document published by Elliniko Metro, carried out by +Design Magazine, it was revealed that the document was not originally created by MnMS, the company that Elliniko Metro directly appointed to design the logo, but rather by Palladian, one of the companies which has submitted bids in the competition.^[78] The two companies were previously based in the same building in Athens, raising further questions.^[78] Elliniko Metro amended the metadata five hours after the official unveiling of the logo, changing among others the name of the author, but had already disseminated the unaltered presentation to media outlets such as Naftemporiki.^[78]

A large number of important archaeological finds, primarily Roman and early Christian and Byzantine, have been discovered during the metro's construction. The project triggered the largest archaeological dig in northern Greek history, covering a 20-square-kilometre (7.7 sq mi) area.^[6] Between the new railway station and Sintrivani/Ekthesi, the metro runs below Egnatia Street (one of Thessaloniki's main arteries). Egnatia follows the Roman Via Egnatia, which connected Rome and Constantinople as one of the two most important roads in the Roman and Byzantine empires.^[79] The portion of the Via Egnatia which passed through Thessaloniki was the city's Decumanus Maximus (main road), and runs below present-day Egnatia Street at 5.4 metres (18 ft) below ground level.^[11]

Although the location of the Via Egnatia in Thessaloniki was known when the metro line was planned, it was uncertain what else was buried nearby. The metro was planned to run at 8 metres (26 ft) below ground, leaving only 2.6 metres (8.5 ft) between it and the ancient road. The discovery of a Byzantine road at Venizelou station was a major archaeological find: 75 metres (246 ft) of the marble-paved and column-lined road was unearthed, with shops, other buildings, and plumbing which one scholar called "the Byzantine Pompeii".^[31] A crossroads, marked with a tetrapylon, was found at Venizelou where the Decumanus Maximus crossed a cardo (a north–south road).^[80] An additional 22 metres (72 ft) of the same road was discovered at the Agias Sofias station.^[80] Issues concerning archaeological finds and the display of artefacts in the metro system are more complex than similar issues surrounding the construction of the New Acropolis Museum.^[80]

Other important discoveries included a headless statue of Aphrodite, fourth-century-AD mosaics, a golden wreath, a bath complex, urban villas, and 50,000 coins.^{[81][82][83][84]} Artifacts from the 1917 fire were also found.^[85]

The discovery sparked controversy in Thessaloniki; Attiko Metro wanted to remove the antiquities and re-assemble them elsewhere, and the city's archaeological services wanted the company to alter the depth of the line and the station entrances. The city council sided with the archaeological services in 2015, three years after the metro was originally planned to begin service.^[11] Mayor Yiannis Boutaris took the case to the Council of State, Greece's highest administrative court.^[86] Attiko Metro redesigned the line, sinking the tunnels to depths from 14 to 31 metres (46 to 102 ft) and providing for mini-museums in the stations similar to the Syntagma metro station in Athens (which houses the Syntagma Metro Station Archaeological Collection).^[87] The Venizelou station will contain an open archaeological site, the world's first metro station to do so.^[6][23]

The archaeological excavations are currently budgeted at €132 million ($149 million),^[6] compared with the original archaeological budget of €15 million ($17 million),^[11] and employ 300 archaeologists.^[87] Over 300,000 artefacts have been unearthed to date.^[6] The archaeological work is being carried out by the Ministry of Culture and Sports' Ephorate of Prehistoric and Classical Antiquities and the Ephorate of Byzantine Antiquities.

Construction delays have made the Thessaloniki Metro the subject of a number of jokes in Greece.^{[88][89][90][91]} News satire websites such as To Koulouri have satirised the metro on numerous occasions with stories such as "Thessaloniki Metro will operate on a 24-hour basis during the Christmas rush"^[92] and "Thessaloniki Metro enters its 763rd day of strike",^[93] and it has been cited in satirical lyrics by the Greek rapper Tus.^[94] Greek prime minister Alexis Tsipras joked about the delays at the 2018 Thessaloniki International Fair: "What's happening with the metro, guys? Will it get built here?"^[95]
