Subway traffic across Oslo has come to a complete standstill following reports of smoke in a tunnel at Tøyen station. Authorities have confirmed that all individuals have safely evacuated the platform as they investigate the source of the smoke, which has been traced towards Carl Berner. Operational leader Anders Aas from the Oslo police has indicated that the smoke might be related to a potential fault in the train tracks or other infrastructure, but no open flames have been discovered.

The immediate response from the police and the transit authority Sporveien has been to suspend all subway operations until further notice. Tone S. Tuhus, a spokesperson for Sporveien, stated that the exact cause of the smoke is currently unknown, emphasizing the priority of passenger safety. With all subway lines halted, commuters have been left looking for alternative transportation methods.

This incident raises concerns about the safety and reliability of the subway infrastructure in Oslo, particularly in light of recent efforts to improve public transportation services. As investigations continue, both transit authorities and the police are expected to provide updates to ensure public assurance and to determine the necessary repairs required to prevent future occurrences of such incidents.
