(IN BRIEF) Siemens Mobility and Sporveien have officially brought Norway’s first CBTC-based metro signalling system into passenger service on a three-kilometre section of the Oslo Metro. The €270 million upgrade will replace all legacy signalling on the 86-kilometre network and integrate the Fornebubanen extension, immediately raising capacity from 28 to 36 trains per hour — a 30% increase, with the potential to reach 40 trains per hour as the full system comes online. The project includes 25 years of digital maintenance and asset-management support through Siemens Mobility’s Railigent X platform, ensuring high system reliability as Oslo pursues its goal of becoming the first zero-emission city. Oslo also marks a European first by using a public LTE network for safety-critical train-control communications. The modernization complements Norway’s broader €2 billion national rail digitalisation programme led by Bane NOR, positioning the country at the forefront of advanced, sustainable rail operations.

(PRESS RELEASE) MUNICH, 2-Dec-2025 — /EuropaWire/ — Siemens Mobility and Sporveien have taken a major step toward modernising Oslo’s metro network with the commissioning of the city’s first advanced Communications-Based Train Control (CBTC) system. Passenger operations have now begun on an initial three-kilometre section, marking the first deployment of this next-generation signalling technology in Norway. The €270 million contract, awarded in 2021, will ultimately replace all legacy signalling across the metro’s 86-kilometre network and integrate the new Fornebubanen line into a single, unified digital platform.

The upgraded network is powered by Siemens Mobility’s Trainguard MT solution, operating at Grade of Automation 2 (GoA2). With this system in place, Oslo Metro can immediately increase throughput to 36 trains per hour, up from 28 — a rise of roughly 30%. The system’s design allows for further expansion, with the theoretical capability to handle up to 40 trains per hour once the full infrastructure is complete, providing more than a 40% uplift compared with pre-modernisation capacity.

This transition aligns with Oslo’s long-term mobility ambitions. The CBTC rollout is supported by a 25-year package of digital maintenance services delivered through Siemens Mobility’s Railigent X suite, enabling intelligent asset management, predictive support and maximum network uptime. These enhancements reinforce the city’s broader goal of becoming the world’s first zero-emission urban centre through cleaner, more efficient transportation.

A landmark element of the project is the secure use of a public LTE mobile network for safety-critical train-control communications — the first such implementation for a metro system in Europe. This innovation significantly reduces infrastructure complexity and provides a forward-looking, scalable communications backbone for future upgrades.

The wider programme includes a full digital overhaul of Oslo’s rail infrastructure and the seamless connection of the 8-kilometre Fornebubanen extension featuring six new stations. Siemens Mobility’s partnership with Sporveien spans nearly 130 years, beginning with early electrified lines such as Holmenkollen, and today reflects a shared commitment to sustainable urban mobility.

Norway’s rail sector as a whole is undergoing a transformation anchored in digitalisation. Bane NOR, the country’s rail infrastructure authority, is advancing a €2 billion national programme to modernise and centralise control of the 4,200-kilometre mainline network and more than 350 stations. Together with projects like Sporveien’s CBTC deployment, Norway is positioning itself as a global reference point for advanced, low-emission, technology-driven public transport systems.
