For decades, Krakow has been Poland’s most discussed – and at the same time most frequently postponed – metro project. What many cities solved with trams or light rail systems, Krakow kept putting off: archaeological constraints, cost issues and competing visions (premetro vs. full metro) blocked decisions – even though Krakow has a well-developed tram network with a length of over 103 km and 25 lines and over 150 million passengers per year, which has also been continuously expanded in recent decades. In September 2025, the city moved beyond the debate and published a detailed two-line metro proposal – potentially Poland’s second metro system after Warsaw.
An ambitious plan
The plan is ambitious but focused. It proposes a two-line network of approximately 28.5–29 km and 29 stations, connecting strategic growth sectors and long, congested tram corridors with high-capacity underground links. The concept aims to bring around 40% of Kraków’s residents within a ten-minute walk of a metro station, offering central operating frequencies of around 2 minutes on core sections and 4-minute headways on branches. City planners and the municipal administration have set a target window to begin construction around 2030, with initial operation envisaged around 2035. Estimated capital costs for the full two-line scheme are in the order of 13–15 billion złoty (ca 3 to 3.5 billion euros).
Why now?
Three factors pushed Kraków towards a full-metro proposal rather than a staged premetro (light rail) approach. First, capacity modelling: updated travel-demand forecasts show that future peak loads on central corridors will exceed what tram-in-tunnel solutions (premetro) can reliably carry without costly enlargement or later disruptive conversion. Second, political momentum after the 2014 referendum and subsequent administrations coalesced around a long-term vision rather than incremental fixes. Third, technical confidence: modern tunnel boring, station construction and automated train technologies make metro deployment in dense historic cores more predictable than earlier generations of projects.
Technical feasibility and certainty of implementation
Yet technical possibility is not the same as delivery certainty. Kraków’s central urban fabric is archaeologically rich; station and shaft sites will require careful survey, mitigation and, where necessary, redesign. The municipal authorities have recognised this up front: environmental impact work, archaeological surveys and a multi-disciplinary advisory council are part of the preparatory package.
Planning and political considerations
The shift from premetro to full metro is fundamentally a choice about capacity, resilience and disruption. A premetro — tram tunnels with tram rolling stock — can be cheaper initially and can be built to deliver benefits early, but it locks specifications (vehicle width, platform height, structural clearances) that make later conversion disruptive and expensive. A full metro is costlier initially, yet it preserves long-term capacity headroom, permits larger cross-sections, and simplifies future automation.
Kraków opted for the latter. The city’s 2025 proposal envisages tunnel geometry, station spacing and platform arrangements consistent with high-capacity metro operation and automated train operation on core sections. That choice carries immediate cost and procurement implications: large civil works, deep station boxes in the central area and a rolling stock procurement strategy that addresses automation, energy economy and depot integration.
Route planning and integration into the network
The starting point of the future metro network is in Nowa Huta, in the area of the industrial complex, where a technical depot and a terminus are also planned. From there, the line will first run via Aleja Róż and Rondo Kocmyrzowskie to Czyżyny, before continuing via stations such as Wiślicka, Prądnik Czerwony, Rondo Młyńskie and Olsza. It then reaches Rondo Mogilskie and Dworzec Główny, the main railway station, which is intended to be the central transport hub of the network.
In the old town area, stops are planned at Stary Kleparz and Teatr Bagatela, as well as an important station under the National Museum. Further south, the line will cross the Vistula River at Rondo Grunwaldzkie, where a major transfer point will be created. Stations such as Ludwinów, with connections to the districts of Dębniki, Podgórze and Kazimierz, are also planned here.
Further along, the network splits: line M1 runs towards Opatkowic, while line M2 continues to Kurdwanów, with several planned terminus stations in this area.
The expected effects are significantly shorter travel times: the journey from Nowa Huta to the National Museum will take only about 26 minutes instead of the current 40 minutes. The journey time from Kliny to the main station will be reduced from about 50 to 24 minutes, and from Kurdwanów to Teatr Bagatela from about 40 to 18 minutes.
The city administration describes the metro project as the most important investment of the coming decade. Initial market analyses are to begin this year and expert reports are to be commissioned. A contract for the technical documentation and environmental impact assessment is scheduled to be concluded in 2026. The actual tender for construction is to take place in 2030 at the latest.
The metro is intended to serve as the backbone that reorganises surface transport. The design of transfers will be important: bus and tram lines must be redesigned as feeder services, and timetables and fares must be integrated to avoid duplication. The city is planning feeder services, Park+Ride and multimodal interfaces – but practical implementation, financing and responsibilities still have to be negotiated between the city, region and state.
Financing and risks
The costs of 13–15 billion złoty require mixed financing: municipal funds, state subsidies, EU funds and phased tenders for risk management. Political continuity will be crucial: large-scale projects need stable leadership across election cycles. Risks lie in archaeological finds, pipe relocations, typical cost increases in tunnel construction and securing construction capacity in a highly competitive market.
Technical key points
Tunneling
- TBM (closed-face EPB or slurry) tunnelling is the likely method for long central drives: it minimises surface settlement, is suited to variable geology and reduces disruption. For very shallow sections or near sensitive heritage fabric, cut-and-cover or sequential excavation methods may be required.
- Ground conditioning, grouting and real-time settlement monitoring will be mandatory in the old town. Archaeological mitigation will be integrated into the tunnelling programme.
Station typologies
- Deep stacked stations (pylon or column layouts) for constrained central sites with transfer concourses. These allow cross-platform transfers but increase vertical circulation needs.
- Shallow single-vault or cut-and-cover stations for suburban and less archaeologically sensitive areas to reduce cost and speed construction.
- Interchange nodes with expanded concourses, step-free access, and multimodal interfaces for trams, buses and bike parking.
Rolling stock & systems
- Automated operation (ATO/GoA2–GoA4) on core sections is a municipal aspiration. Rolling stock will therefore need onboard ATP/ETCS-style train control compatibility or CBTC for metro operations, redundant safety systems and energy-efficient traction with rapid recharge/regenerative braking.
- Car length / capacity: metro trains sized for 2–2.5-minute central headways, coupled for peak capacity; depot and stabling designs must reflect train formation and maintenance needs.
- Depot siting: strategic depots on network periphery with shunting links to lines to minimise central urban land take.
Timeline of the Krakow metro

- 2014 — Local referendum (55.11% in favour) shifting political debate in favour of a metro.
- 2021 — Feasibility study recommending premetro variant for initial axis (technical and cost appraisal).
- 2024–2025 — Renewed modelling and political decisions; debate shifts to full-metro solution.
- 24 Sept 2025 — City unveils two-line metro proposal: ~28.5–29 km, 29 stations, target start ~2030, opening ~2035; estimated cost 13–15 billion złoty.
- 2025–2026 — Environmental impact assessments, archaeological surveys, detailed route optimisation and financing negotiations.
- 2026–2029 — Secure multi-level funding (municipal, national, EU); final design and procurement packaging; tendering for TBMs, stations and systems.
- ~2030 — Planned construction start (TBMs, shafts, station boxes).
- ~2035 — Target for initial passenger operations on first sections (subject to funding and procurement).
- Early 2040s — Full network phased completion if staged approach adopted.
Conclusion
In 2025, Krakow took a decisive step from endless studies to concrete commitment. If the implementation is successful, the project will fundamentally change the mobility and cityscape of a medium-sized European city. Success depends on careful archaeology, robust financing, smart procurement and intelligent network connectivity. For planners across Central Europe, Krakow is a test case: can a city in the 21st century balance heritage, cost pressures and genuine capacity needs in such a way that a metro becomes a reality?
