The prestigious international magazine Engineering News-Record (ENR) has recognized the Fyrspåret Lund–Arlöv project, developed by the OHLA–NCC joint venture for Trafikverket, as one of the world’s best railway infrastructures in 2025. This accolade, one of the most significant in the construction sector, rewards the innovation, sustainability, and technical excellence of a project that redefines European standards in railway infrastructure.

The Lund–Arlöv project has modernized one of Sweden’s main railway corridors, connecting Malmö with Stockholm, by expanding the 11-kilometer section between Lund and Arlöv from two to four tracks. This upgrade has increased capacity, improved punctuality, and strengthened the sustainability of rail transport, consolidating the modal shift toward more efficient and environmentally friendly solutions. Thanks to this transformation, the corridor now handles up to 650 trains daily and serves more than 80,000 passengers, becoming a key infrastructure for sustainable mobility in the country.

The project included highly complex technical works such as the construction of temporary tracks to maintain active rail operations, major earthworks, the execution of 2.5 km of retaining walls, a 400-meter tunnel in Åkarp using the “cut and cover” technique with diaphragm walls, the renovation of Burlöv, Åkarp, and Hjärup stations, and the construction of the new Klostergården station. It also involved 9 railway bridges, 13 road bridges, 2 underpasses, 7 km of temporary roads, and 5 pumping stations. The four tracks entered service in 2023, and additional phases were completed in 2025, with formal delivery on May 5, 2025.

The project stands out for its pioneering use of digital technologies, including a real-time digital twin integrating BIM, GIS, and drones to coordinate data, plan in 4D, and manage risks. A Common Data Environment (CDE) was created in the cloud using Autodesk BIM 360, centralizing models, schedules, and documentation, and digital simulations were carried out for critical operations such as bridge construction over the E6 motorway.

Mobile applications were also implemented for inspections and instant traceability, enabling precise execution of critical structures and continuous quality control. Sustainability was another cornerstone of the project, achieving significant reductions in greenhouse gas emissions through optimized concrete, recycled steel, and non-fossil fuels, as well as reusing 80% of temporary materials and surplus. This approach earned the Sweden Green Building Award 2022 for sustainable infrastructure.

The project also had a positive impact on local communities by reducing noise through trench tracks and acoustic barriers, improving accessibility with modern stations such as Klostergården—integrated into the urban fabric and respectful of the Höjeådalen nature reserve—and increasing train frequency to enhance regional connectivity.
