Strukton has been awarded a significant contract by Trafikverket to build a new switching station at Gerstaberg, located between Södertälje and Järna. This facility will connect the new overhead contact lines of the Ostlänken high-speed rail link with the existing contact lines on the Västra Main Line.
The project is scheduled for final inspection in August 2028 and represents an important step in Sweden’s rail modernisation programme.
Gerstaberg Switching Station is part of the Ostlänken project – a 160 km double-track line between Järna and Linköping, expected to be completed by 2035. Once operational, travel time between Stockholm and Linköping will be reduced from two hours to just one hour, significantly improving connectivity and sustainability.
By delivering this critical infrastructure, Strukton continues to play a key role in shaping the future of rail transport in Sweden.
Expanding the electricity grid is crucial to support increasing demand from renewable energy, electric mobility, gas‑free homes and growing data‑center capacity. A larger and stronger grid ensures reliability, prevents congestion and enables the seamless integration of solar, wind and other sustainable energy sources.
Modern energy networks rely on extensive civil engineering works, including the construction of high‑voltage substations, transmission‑line foundations, access roads, cable routes and site preparation for electrical stations. These works form the physical backbone that allows grid operators to expand capacity safely and efficiently.
Smart grid solutions improve network performance by capturing, storing and reusing energy more intelligently. Technologies such as mobile or modular substations, regenerative systems and energy‑storage units help reduce peak loads, increase efficiency and make better use of the existing grid — reducing both costs and environmental impact. An example is Strukton’s Energy Bank (OV energiebank).
Reliable rail transport depends on dedicated AC and DC power‑supply systems, including converter stations, feeder stations, traction‑power substations and mobile energy‑supply units. These systems enable stable and resilient power delivery for heavy rail, metro, tram and light‑rail networks across Europe.
Converter stations and feeder stations ensure that rail networks receive the correct voltage and frequency, even as traffic intensifies or train weights increase. Mobile and permanent installations provide flexibility, strengthen weak network sections and support international rail corridors with varying technical requirements.
Railway construction in European urban areas faces several challenges, including limited space, strict environmental regulations and the need to manage noise and vibration in line with European rail standards. Complex public transport networks, high population density and the demand for uninterrupted urban mobility add further constraints.
The cost of constructing a new railway line in Europe depends on several key factors, including route length, local geography, environmental requirements and the complexity of the surrounding rail infrastructure. Prices can range from several million to hundreds of millions of euros, depending on whether the project involves urban environments, tunnels, bridges or upgrades to existing public transport networks.
