The Centralny Port Komunikacyjny (CPK), Poland’s flagship multimodal transport project, has opened a tender for the design and construction of an underground railway tunnel and station located directly beneath the future CPK Airport. The scope includes the full station structure and platform hall. Bidders have until 12 December 2025 to submit applications for the competitive dialogue stage. The contract is scheduled to be awarded in early 2027, and the project is slated for completion in 2031.
The railway tunnel and underground station are key parts of the CPK Airport plan and will help build vital rail connections across Poland. The procurement process will be divided into two segments, with up to five shortlisted participants in each. The winning contractor will be responsible for both the design and construction of the complete tunnel and station complex.
“Following the launch of the terminal tender, we’re moving forward with another major procurement – this time for the tunnel and railway station beneath the airport. We’re seeking a contractor with proven experience in large-scale tunnelling and infrastructure projects in Poland,” said Maciej Lasek, Government Plenipotentiary for CPK and Deputy Minister of Infrastructure.
The tunnel, stretching roughly six kilometres and encompassing a volume of 3.5 million cubic metres, will be among the largest of its kind in Poland. Its size will surpass both the Limanowa rail tunnel and the S3 road tunnels near Kamienna Góra. Running along an east–west alignment, it will accommodate railway lines 5, 85, and 88, providing direct connections to Warsaw in the east and Gdańsk, Katowice, and Łódź to the west.
“The tunnel is an integral part of high-speed line No. 85 linking the CPK Airport with Warsaw and Łódź. The station will form a fully integrated part of the terminal, enabling smooth and rapid transfers between rail and air,” said Dr Filip Czernicki, CEO of CPK.
The tender encompasses two primary lots:
- Part 1: design and construction of the eastern and central tunnel sections, including the station.
- Part 2: design and construction of the western section and junction area.
Each lot includes optional works for track systems and internal transport equipment (UTB) to support short-distance passenger and cargo movement.
“The CPK Airport Station and rail tunnel will feature a modern design and cutting-edge technologies, ensuring fast and convenient transfers for passengers,” added Piotr Rachwalski, CPK Management Board Member for Railway Investments. Bids will be assessed on price, methodology, and warranty terms, with contract awards anticipated in early 2027.
According to the current schedule, the underground station and tunnel should be ready by the end of 2032, alongside the launch of the high-speed rail link between Warsaw and Łódź. The remaining parts of the national “Y” network—from Łódź to Wrocław and Sieradz to Poznań—are expected to open by 2035.
