Siemens and Sporveien launch CBTC on first section of Oslo metro

Siemens Mobility and Sporveien put the radio-based Trainguard MT train control system (CBTC, grade of automation GoA2) into passenger service on a first 3 km section of the Oslo metro on 2 December 2025. The EUR 270 million contract, awarded in 2021, covers the complete replacement of the signalling system across the 86 km network and the integration of the 8 km Fornebubanen with six stations; no completion date for the whole network is given. According to Siemens, capacity rises from 28 to 36 trains per hour (about 30 per cent), with up to 40 technically possible, and Oslo is the first metro in Europe to use public LTE mobile networks for safety-critical train control.
