The A and B metro lines in Lyon are experiencing partial disruptions due to an incident involving a passenger. According to the TCL network and Mamb, Line A has been partially interrupted since 12:10 pm on Monday, September 21. The disruption followed an "intrusion in the tunnel at the Hôtel de Ville station," which required the temporary stoppage of train traffic and the evacuation of three trains underground as a safety precaution. Currently, Line A is operating only between the stations Laurent Bonnevay and Vaulx-en-Velin La Soie. Officials estimate that normal service will resume by 5:00 pm. The incident has also affected Line B due to the electrical interdependence of the two lines at the Charpennes Charles Hernu station. As a result, Line B is now running only between Saint-Genis-Laval Hôpital Lyon Sud and Gare Part-Dieu Vivier Merle. To help passengers continue their journeys, relay buses have been deployed between Charpennes Charles Hernu and Vaulx-en-Velin La Soie. These buses are intended to maintain the flow of travelers despite the partial service disruption. Information kiosks and assistance devices have been set up at affected stations to provide passengers with updates and guidance. The TCL network and Mamb are working to resolve the situation and restore full service. Officials have estimated that both Line A and Line B will resume normal operations by 5:00 pm on Monday, September 21. This incident highlights the interconnected nature of the metro system and the measures taken to ensure passenger safety. While disruptions can be inconvenient, the deployment of relay buses and information tools aims to minimize the impact on daily commuters. The authorities are monitoring the situation closely to ensure a smooth resumption of services.
