Správa železnic Launches EUR 341M Ruzyně–Kladno Line Modernization

PRAGUE, CZECH REPUBLIC – State infrastructure manager Správa železnic (SŽ) has officially commenced modernization work on the 15-kilometer Ruzyně–Kladno railway line, with completion scheduled for 2029. A consortium comprising Subterra, OHLA ŽS, Elektrizace železnic Praha, and Swietelsky Rail secured the contract with a winning bid of CZK 8.279 billion (EUR 341.24 million). This upgrade represents the longest single phase of the broader Prague–Airport–Kladno rail link project.

What Is the Full Scope of This Project?

The modernization of the Ruzyně–Kladno section will upgrade 15 kilometers of track to double-track standards, boosting maximum train speeds to 145 km/h. This infrastructure upgrade will halve travel times on the section to seven minutes. Structurally, the project includes the reconstruction of three existing stations, the decommissioning and demolition of one station, and the construction of two new stops in Jeneček and Velké Přítočno. To improve regional multi-modal integration, a new station will feature a park-and-ride facility designed for over 300 vehicles alongside direct bus terminal connections. Safety improvements will replace all existing level crossings on highly trafficked roads with modern overpasses or underpasses.

Key Project Data

How Does This Compare to Similar Projects?

The CZK 8.279 billion (EUR 341.24 million) capital expenditure for the 15-kilometer Ruzyně–Kladno line highlights the high cost of urban-adjacent rail upgrades compared to international maintenance and greenfield initiatives. For comparison, the UK’s High Speed 2 (HS2) program launched a market engagement exercise for a £1.24 billion (EUR 1.45 billion) package of interim maintenance contracts, demonstrating the massive scale discrepancy between localized capital upgrades and high-speed network maintenance frameworks (Source: Construction News, 2026). Furthermore, while the Ruzyně–Kladno line relies on traditional public procurement, the adjacent airport link sections are slated to be delivered via a Public-Private Partnership (PPP) model, reflecting a growing Central European trend of leveraging private capital for high-priority airport rail connections. The exact allocation of European Union co-financing versus Czech national budget funding for this specific 15-kilometer section was not publicly disclosed at the time of publication.

Note: Independent verification of the project leadership resolved a discrepancy in regional reports; while some initial documentation incorrectly attributed the project to national carrier Czech Railways (ČD), the state infrastructure manager Správa železnic (SŽ) is the sole contracting authority.

Editor’s Analysis

This project marks a critical shift in the Czech Republic’s approach to suburban transit, transitioning legacy single-track regional lines into high-capacity commuter corridors. By integrating park-and-ride facilities and planning a PPP model for the airport link, Czech planners are aligning with broader Western European transit-oriented development strategies. This infrastructure modernization supports the Czech Republic’s wider 2025-2026 high-speed rail investment trend, which prioritizes regional integration and advanced technology adoption to relieve highway congestion (Source: Czech Ministry of Transport, 2025).
