Train Service Suspended Between Naples Campi Flegrei and Pozzuoli Due to Bradysism
Naples, June 12, 2026, 21:02 – Rail traffic between Naples Campi Flegrei and Pozzuoli Solfatara will be suspended as a precautionary measure starting from 1:00 AM on June 13. This decision comes in response to the ongoing bradysism phenomena affecting the Campi Flegrei area, a volcanic caldera west of Naples.
Precautionary Measure Due to Carbon Dioxide Detection
The suspension, coordinated with the Prefecture of Naples, is primarily due to the detection of carbon dioxide within the Flegrea Tunnel. This tunnel is located in the section between the service areas of Bagnoli-Agnano Terme and Pozzuoli Solfatara. The presence of elevated CO2 levels necessitates immediate action to ensure the safety of passengers and railway personnel.
Rfi Campania, the regional railway infrastructure manager, stated in a note, “Technical checks and interventions are necessary for the regular operation of the railway service.” This indicates that the suspension is not merely a temporary halt but will involve a thorough assessment and potential remediation efforts within the affected tunnel section.
Disruptions Expected for Commuters
The suspension of service is expected to cause significant inconvenience for users of Line 2 of the metropolitan railway and regional transport services. Commuters traveling between Naples Campi Flegrei and Pozzuoli Solfatara will need to seek alternative transportation methods. The exact duration of the suspension has not yet been specified, as it depends on the outcome of the technical checks and interventions.
Bradysism is a phenomenon of gradual uplift or descent of the Earth’s surface, common in volcanic areas like the Campi Flegrei. While often slow and imperceptible, it can lead to seismic activity and changes in gas emissions, posing potential risks to infrastructure. Authorities are closely monitoring the situation to ensure public safety and minimize disruption.
Further updates on the resumption of train services will be provided by Rfi Campania and local authorities as the situation evolves and safety assessments are completed. Commuters are advised to check official channels for the latest information before planning their journeys.
