The Copenhagen Metro is publicly owned, yet its daily operation has been entrusted first to Milan’s ATM and now to a consortium led by France’s RATP. The explanation lies not in a lack of Danish expertise, but in the way the capital deliberately organised its driverless railway.
Copenhagen is not handing its Metro to another country
The first essential distinction is between ownership and operation. The Copenhagen Metro remains a publicly owned Danish transport system. Its infrastructure, stations, trains and principal technical assets belong to Metroselskabet, which is controlled by the Danish state and the municipalities of Copenhagen and Frederiksberg. Metroselskabet determines how the network should develop, establishes the standards to be met and supervises the operator’s performance. The external company is contracted to run the daily service and undertake most of its maintenance, including traffic control, passenger assistance, cleaning, repairs, cybersecurity and the management of technical systems. ATM did not own the Copenhagen Metro, and RATP will not own it either: both have served, or will serve, as contractors operating Danish public assets under Danish public authority.
Why must the operation be put out to tender?
According to Metroselskabet, Danish legislation requires the Metro’s operation to be awarded through a competitive tender to a private operator. Copenhagen cannot simply renew the existing agreement indefinitely or transfer the service directly to a municipal department without changing the institutional and legal structure under which the Metro was created. The incumbent must periodically compete against other qualified bidders, even when the service is performing well. A Danish company could theoretically win such a competition, but in practice very few Danish businesses have experience operating and modernising a large, fully automated metro running 24 hours a day. The eligible market is consequently dominated by multinational transport groups with experience from several complex urban railway systems.
From Milan’s ATM to a RATP-led consortium
Metro Service, controlled by Milan’s municipal transport company ATM, has operated the network since 2008 and will remain responsible until September 2027. During that period, the Metro expanded beyond the original M1 and M2 routes to include the Cityringen M3 and the M4, while establishing an exceptionally strong reliability record. Metroselskabet reported operational reliability of 99.3 per cent in 2025, when the network carried 135 million passengers. ATM’s failure to retain the contract should not therefore be interpreted as evidence that the Italian company ran the service badly. Fixed-term competitive tendering is designed precisely so that a successful incumbent can still be replaced when another bidder presents what the authority considers a stronger proposal for the next phase of the network’s life.
Who will actually operate the Metro from 2027?
The incoming operator is KBH Metro Partner, a Danish company supported by RATP Dev, the wider Paris-based RATP group and companies belonging to Singapore’s ComfortDelGro, including SBS Transit Rail. Describing the outcome simply as a French takeover is therefore misleading. The operating company will be based in Denmark, work under Danish law and employ personnel in Copenhagen, while drawing technical and organisational support from French and Singaporean transport groups. RATP contributes experience from one of Europe’s largest urban transport networks and several automated metro projects, while SBS Transit brings knowledge from Singapore’s intensively used rail system. Metroselskabet specifically required bidders to demonstrate experience in operating, maintaining and modernising automated metros.
Why international experience matters now
The next operating period will involve considerably more than keeping the existing trains moving. The oldest Copenhagen Metro lines have been in service since 2002, meaning that signalling equipment and other technical installations will require extensive renewal. Two more M4 stations are expected to open in Outer Nordhavn in 2032, while the proposed M5 will eventually introduce another major component to the capital’s network. Copenhagen consequently sought an operator capable of managing normal service while participating in complicated renewal and expansion projects. The Metro runs continuously, without drivers on board, and at peak times trains can arrive every 90 seconds. A failure in signalling, power, communications or platform systems can rapidly affect the entire network. This level of operational integration helps explain why only a limited number of large international groups are able to satisfy the tender requirements.
The workforce will remain largely Danish
A change of operator does not mean that the people currently running the Metro will be replaced by workers arriving from Paris or Singapore. The contract is covered by Danish rules protecting employees during a transfer of undertaking. Metroselskabet has emphasised the importance of retaining the competence accumulated by Metro Service’s existing workforce, and many employees are expected to move to the new organisation. The most delicate part of the transition concerns the transfer of procedures, maintenance records, IT systems, spare-parts inventories and safety responsibilities rather than the wholesale replacement of staff. This is also why the new operator was selected well before the handover: KBH Metro Partner, Metro Service and Metroselskabet have more than a year to prepare for the change without interrupting passenger services.
Does outsourcing necessarily produce a better service?
Competitive tendering is intended to place pressure on operators to control costs, improve working methods and accept precise obligations concerning reliability, cleanliness, maintenance and passenger satisfaction. It can also give a comparatively small metro access to expertise gathered across much larger international networks. However, the model has disadvantages. Preparing a metro tender is itself a complicated undertaking, only a small group of multinational companies can realistically compete, and every handover carries operational risks. A public authority may also become excessively dependent on contractors if it no longer retains sufficient technical expertise of its own. The decisive issue is therefore not whether a foreign company is inherently better than a Danish one, but whether periodic competition produces improvements substantial enough to justify the disruption and organisational complexity it creates.
Stockholm uses a very similar model
The closest Nordic comparison is Stockholm, where Region Stockholm retains public control of the transport system but contracts Metro operations to external companies. Hong Kong’s MTR operated the Tunnelbana from 2009 until November 2025. It was then replaced by Connecting Stockholm, a joint venture between the British Go-Ahead Group and Singapore’s ComfortDelGro – one of the groups now supporting Copenhagen’s future operator. During the Stockholm handover, approximately 3,300 employees changed employer and responsibility had to be transferred for around 150 IT systems, maintenance information and spare-parts stocks. Like Copenhagen, the Swedish capital uses competition between international operators while the public authority retains ownership, planning powers, fares and overall responsibility for the network.
Helsinki keeps Metro operation in public hands
Helsinki demonstrates that foreign or private management is not technically inevitable. Its Metro is operated by Metropolitan Area Transport Ltd, generally known as Kaupunkiliikenne, a publicly owned company that continued the activities of Helsinki City Transport from 2022. The regional authority HSL plans and orders the service, while Kaupunkiliikenne operates and maintains the trains and manages important parts of the Metro and tram infrastructure. Finland still purchases trains, signalling systems, engineering work and other specialist services from international companies, but the core operation of the Helsinki Metro remains within a locally controlled public organisation. The contrast with Copenhagen is therefore institutional rather than technological: the two cities made different decisions about where public responsibility should end and contracted activity should begin.
Oslo also relies on a municipal operator
The Oslo T-bane follows a model closer to Helsinki’s. Ruter plans, coordinates and markets public transport across Oslo and Akershus, while the Metro is operated by Sporveien T-banen. Sporveien is owned by the City of Oslo and is responsible not only for running the trains but also for substantial parts of the Metro and tram infrastructure. Foreign companies still supply vehicles, technology, engineering expertise and construction services, and other areas of Norwegian public transport are exposed to competitive tendering. Nevertheless, the operational core of Oslo’s urban railway has remained under municipal ownership rather than being periodically transferred between multinational concessionaires.
Iceland has no directly comparable system
Iceland has no metro, tramway or urban railway comparable to those of Copenhagen, Stockholm, Helsinki and Oslo. Public transport in the Reykjavík capital region remains centred on buses, while the planned Borgarlína system is being developed as bus rapid transit rather than an underground railway. International companies may provide vehicles, technology, consultancy and construction services, but Iceland cannot currently offer a meaningful comparison with Copenhagen’s outsourced metro-operation model.
There is no single Nordic approach
The Nordic capitals are divided between two broad systems. Copenhagen and Stockholm maintain public ownership and strategic control while awarding daily Metro operations to companies selected through competition, often leaving foreign groups as the strongest candidates. Helsinki and Oslo instead retain operations within publicly owned local companies, although both depend on international suppliers for equipment and specialist expertise. None of these cities is completely self-contained, but they place the boundary between public management and external contracting in different positions. European procurement rules encourage transparent competition in many areas, yet they do not force every Nordic city to outsource its Metro. Copenhagen’s reliance on ATM and RATP is the result of Denmark’s specific legislation and the organisational choices made when the Metro was established.
The real question is whether the model works
Copenhagen does not require foreign management because Danish workers or engineers are incapable of operating the Metro. It requires a private contractor because that is how the system has been legally structured, and the specialised international market makes a foreign-backed winner highly probable. The real test will come after September 2027. RATP, ComfortDelGro and KBH Metro Partner will inherit one of Europe’s most reliable automated railways rather than a service in need of rescue. If they preserve its performance while successfully renewing its oldest systems, the competitive model will have a powerful argument in its favour. If the transition produces disruption or weakens locally accumulated expertise, Copenhagen may eventually face a more fundamental political question: why should a publicly owned Nordic Metro not be operated by a permanent public company, as it already is in Helsinki and Oslo?
