The current train strike is expected to have major action on September 18, 2025, which is a general national strike called by several unions including the largest SNCF unions in France. This strike is part of widespread protests against government budget measures and is planned to severely disrupt train services, with only 30 to 40% of trains running on several major networks. The strike action on September 10, 2025, already took place as a national blockade, and the next major strike day is set for September 18, 2025. Information suggests that disruptions will be significant, especially on long- distance and regional trains, but the exact end date of the strike activity beyond these dates is not specified. Typically, disruption announcements come 1-2 days in advance for passengers. So far, the strikes are planned for specific days rather than indefinite ongoing action.
Therefore, the large-scale national strike will at least end after September 18, 2025, but there could be further industrial action depending on negotiations and union decisions.
