Subway services in Oslo have resumed on select lines following a full suspension that occurred on Saturday afternoon. The disruption was caused by smoke developing in the tunnel between Carl Berner and Tøyen subway stations, leading Ruter, the public transportation agency, to suspend all lines to ensure passenger safety.

Although service has been restored, Ruter warns passengers to expect significant delays as operations are still being adjusted. The impacts of the smoke incident may linger, causing inconvenience for users of the subway system. This situation highlights the importance of safety protocols in public transport systems and the challenges that arise during emergencies.

The return to operations is a relief for many daily commuters who rely on the subway for transportation in Oslo. However, the need for caution and the response by transportation authorities underscores the ongoing commitment to maintaining high safety standards in public transit systems in Norway, as they navigate both operational challenges and the expectations of the public regarding service reliability.
