CPK Poland: High-Speed Rail Tunnel Project & Railway Technology

“`html

Introduction

Centralny Port Komunikacyjny (CPK) has initiated a major procurement process for the design and construction of a six-kilometer tunnel and railway station beneath the new CPK Airport, a key element in the development of Poland’s transport hub.

Project Scope

The tender encompasses the design and construction of a six-kilometer tunnel and an underground station. This infrastructure will provide an interchange between air and high-speed rail, connecting the airport with Warsaw, Łódź, Gdańsk, Katowice, and Poznań. The tunnel will have a total volume of 3.5 million cubic meters. The project is divided into two main lots, each covering distinct sections of the tunnel and optional work packages for installing track systems and internal transport equipment (UTB).

Timeline and Procurement

Applications for the competitive dialogue procedure are open until 12 December 2025. Contract awards are scheduled for the first quarter of 2027, with completion planned by 2031. Bids will be evaluated based on price, technical methodology, and warranty conditions. The railway station and tunnel beneath CPK Airport are scheduled to open by the end of 2032, coinciding with the start of operations on the Warsaw–Łódź high-speed line.

Strategic Importance

The rail tunnel will run along an east–west axis, carrying railway lines 5, 85 and 88, and will form a strategic part of the national high-speed rail network. It will link Warsaw to the east with 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 project is a key component of the broader CPK high-speed rail programme, which aims to transform Poland’s transport network through new, fast, and fully electrified rail lines.

Project Impact and Broader Context

The CPK Airport Station and rail tunnel will feature a modern design. The CPK programme combines air, rail, and road infrastructure to create a multimodal hub positioned between Warsaw and Łódź. The CPK project is expected to strengthen economic development, attract foreign investment, and enhance mobility across Central Europe. The complex will enable travellers to reach most major Polish cities within two and a half hours by train and facilitate seamless international connections.

Conclusion

The Centralny Port Komunikacyjny (CPK) is proceeding with the procurement for the tunnel and railway station beneath the airport, with applications open until December 12, 2025, and completion targeted for 2031-2032. This infrastructure is a key component of the high-speed rail network and will integrate air and rail transport to connect major Polish cities.

Company Summary

Centralny Port Komunikacyjny (CPK): The Centralny Port Komunikacyjny (CPK) is a Polish government project focused on the development of a major transport hub, combining air, rail, and road infrastructure. It aims to integrate high-speed rail directly beneath the airport terminal, providing a model for sustainable, multimodal transport.
