PORR has been awarded a contract worth €400 million for the construction of a high-speed rail tunnel in Łódź, Poland. The project forms part of the Central Airport infrastructure development. This is one of several ongoing rail construction projects for the company, which is experiencing increased activity in the sector, particularly through the use of its proprietary Slab Track Austria system. Substantial investments in rail infrastructure are currently being made across Europe. Austria’s ÖBB is investing €3.5 billion in its national rail network this year. Germany has allocated €1.7 billion, Poland €3.6 billion, and the Czech Republic €1.46 billion in 2025, with a total of €2 billion planned there by 2026. Forecasts from Euroconstruct anticipate that railway construction in Poland will grow by over 35% by 2027. PORR is involved in several projects across these countries, many of which incorporate its slab track system. In Austria, PORR is part of the consortia responsible for installing slab track infrastructure in major projects including 33 kilometres of the Koralm Tunnel and 27.3 kilometres of the Semmering Base Tunnel. The company is also constructing the 25.2-kilometre Pfons-Brenner section of the Brenner Base Tunnel, one of Austria’s largest infrastructure projects. In Germany, PORR is contributing to Stuttgart 21, currently the country’s largest railway construction project. The company installed 34.5 kilometres of its slab track system within tunnels connecting Stuttgart Central Station to surrounding transit lines and the airport. PORR has also strengthened its rail sector presence in Germany through the acquisition of a majority stake in Knape Bahnbau GmbH, with the aim of expanding its operations in southern Germany. In Romania, PORR was awarded a €428 million contract to upgrade a 32.6-kilometre section of the Craiova – Drobeta Turnu Severin – Caransebeș railway line. The project includes the reconstruction of bridges, culverts, tunnels, and six stations. In Bucharest, PORR is also modernising part of the city’s tram line 40 under a €150 million contract. PORR has increased its market presence in the Czech Republic, securing multiple new projects in 2025. The company’s order backlog for 2026 in the country already exceeds €100 million. In Poland, PORR continues to expand its role in major national rail development initiatives. Recent contracts include upgrades to the LK354 Poznań–Piła line and the LK356 Wągrowiec–Gołańcz route. The Łódź tunnel project marks the first application of Slab Track Austria in a tunnel setting in Poland. Slab Track Austria, PORR’s patented modular slab track system, replaces traditional ballast and sleepers with a fixed concrete base. It is designed for high-speed rail and offers benefits such as durability, track stability, low maintenance requirements, and reduced noise and vibration levels. The system is currently used in several European infrastructure projects and has become a core component of PORR’s railway construction activities.
