CPK approves key planning stage for Sieradz–Poznań high-speed rail link

Centralny Port Komunikacyjny (CPK) has approved the Program and Spatial Concept (KPP) for Railway Line No. 85, advancing plans for the high-speed rail connection between Sieradz, Kalisz, Pleszew, and Poznań. This section forms part of the “Y” line, a strategic infrastructure project linking Warsaw, CPK, Łódź, Poznań, and Wrocław.

The approved KPP outlines preliminary technical and spatial assumptions, including new tracks and stations, and serves as the foundation for construction design. With this milestone reached, CPK is beginning the next stage of work: developing the construction design, scheduled to continue through the third quarter of 2026. The company aims to submit a construction permit application by the end of that year, with construction expected to begin in early 2028. The line is projected to be operational by 2035.

Environmental permit applications for the 146-kilometre route have already been submitted. The design speed for passenger trains on this segment is 350 km/h. Once completed, the high-speed line will cut travel time between Warsaw and Poznań to 1 hour and 38 minutes.

This route forms part of the Trans-European Transport Network (TEN-T), a European Union initiative aimed at enhancing cross-border transport and integration. Funding of PLN 162 million for the Sieradz–Poznań section was secured through the EU’s Connecting Europe Facility (CEF2), underlining its significance for regional and European mobility.

The project is being developed by CPK in collaboration with the BBF and IDOM engineering consortium.
