How can you plan for these disruptions?

In light of these disruptions, there are a few good habits to adopt. Before traveling, check the Bonjour RATP and SNCF Connect apps for real-time information. As the disruptions mainly affect evenings and weekends, if you are returning home late at night or have plans to go out this weekend, allow extra time or plan alternative routes. For lines with replacement buses, allow for an additional 20 to 30 minutes of travel time.

In short, this week from December 8 to 14, 2025, will continue to be marked by work on the Île-de-France network. The RATP and SNCF are taking advantage of this period to modernize and maintain their infrastructure, which will inevitably cause some inconvenience. But rest assured, most of the disruptions will occur in the evening after 9 p.m. and on weekends, thus avoiding rush hour. If you really need to travel late at night, don't hesitate to use the Noctilien bus lines, which continue to run throughout Paris and the Île-de-France region all night long.
