Port Polska has begun competitive dialogue with four shortlisted contractor teams for the design and construction of the tunnel and underground railway station that will form the rail hub beneath Poland’s new national airport, marking another major step forward for one of Europe’s largest transport infrastructure programmes.
The contract covers the delivery of an approximately 6km-long tunnel together with a six-platform underground railway station and platform hall that will connect directly with the airport’s multimodal interchange. Once completed, the facility will enable seamless transfers between air services, High-Speed Rail, regional and long-distance rail networks.
The underground station will serve east-west rail services from the day the airport opens and will also accommodate future north-south services following completion of the CMK North line, creating one of the country’s most important rail interchanges.
Four consortia have progressed to the competitive dialogue stage:
Mirbud S.A. (lead partner), Kobylarnia S.A. and Torpol S.A.
Mostostal Warszawa S.A. (lead partner), NDI S.A., NDI Sopot S.A. and Intercor Sp. z o.o.
PORR S.A. (lead partner) and Gülermak S.A.
Strabag Sp. z o.o. (lead partner) and TYM-BUD Zakład Remontowo-Budowlany Waldemar Tymoszewski.
The selected consortium will be responsible for designing and constructing both the tunnel and the station complex. The procurement has been divided into two principal packages covering the eastern and central tunnel sections, including the station and interchange, together with the western tunnel section and associated rail junctions. Optional works include the railway track system and the supply, commissioning and maintenance of lifting and transport equipment.
According to Port Polska, the underground station and platform hall will have a total volume exceeding 1.6 million m³, making it almost three times larger than Warsaw Central Railway Station. The tunnel will extend for around 6km and vary between 50m and 160m in width.
Piotr Malepszak, Government Plenipotentiary for Centralny Port Komunikacyjny (CPK), said the underground facility would be designed to provide a safe, fully accessible and intuitive passenger environment with barrier-free access and modern passenger information systems.
Dr Filip Czernicki, CEO of Centralny Port Komunikacyjny, said the programme represented transport infrastructure on an unprecedented scale in Poland and was intended to create seamless integration between different transport modes while providing efficient passenger handling.
Dariusz Kuś, Member of the Management Board responsible for airports, said the competitive dialogue would help ensure the procurement delivers the best technical and commercial solution for a project of this complexity.
The procurement process is expected to conclude with contract award in the first quarter of 2027, with construction scheduled to begin towards the end of 2027. The tunnel and underground station are planned to open at the end of 2032, alongside the new High-Speed Rail line between Warsaw and Łódź. The remaining sections of the High-Speed Rail “Y” network serving Wrocław and Poznań are expected to follow by the end of 2035.
Port Polska has also released a new visualisation showing the proposed underground railway station and tunnel beneath the future airport. The video can be viewed here: Port Polska News – Underground railway station visualisation
