Project Profile: Oslo’s Fornebu Line (Fornebubanen) Metro Extension

The Fornebu Line is a critical underground metro expansion project in Oslo, Norway, engineered to connect the Majorstuen transit hub with the rapidly developing Fornebu peninsula. This 8.5-kilometer line utilizes advanced tunneling techniques and adds six modern stations to enhance urban mobility, reduce surface-level congestion, and support significant regional economic growth.

Technical Specifications

The core of the Fornebu Line is an 8.5 km twin-tube tunnel constructed through challenging urban geology, requiring precise drill-and-blast excavation methods to minimize surface disruption. The project includes six new underground stations: Skøyen, Vækerø, Lysaker, Fornebuporten, Flytårnet, and Fornebu Senter. Each station is designed not only for high-capacity passenger flow but also as a distinct architectural landmark, with significant contributions from leading firms like Zaha Hadid Architects and A-lab. Integration with the existing Oslo Metro at the complex Majorstuen junction is a critical engineering challenge. The line is designed for a high frequency of service, with an initial capacity of up to 8,000 passengers per hour per direction, utilizing modern six-car rolling stock.

Key Takeaways

• Strategic Connectivity: The line provides a high-speed, direct link between Oslo’s central transport network and the Fornebu peninsula, a major hub for business and residential development, drastically reducing travel times.
• Economic Catalyst: By enhancing accessibility, the project is a key enabler for urban development and is projected to support the creation of up to 20,000 jobs, unlocking the economic potential of the region.
• Sustainable Urban Mobility: The Fornebu Line offers a high-capacity, zero-emission public transport alternative to private vehicles, directly addressing Oslo’s goals for traffic congestion reduction and environmental sustainability.
