Buses 192, 197, and 394 will be reinforced.

Whenever possible, we encourage you to use alternative lines and to postpone your travel as much as possible.

What are these interruptions for ?

Maintain the infrastructure, modernize the line and prepare it for the arrival of future trains.

Among the work planned for this autumn, preventive maintenance operations are being carried out on the infrastructure to the north. The replacement of a civil engineering structure, located in the Paris Nord area, requires major preparatory work, which leads to the suspension of the RER B interconnection at Gare du Nord.

In order to make the operation of the line more robust, especially during incidents, traffic management facilities to the south of the line are being upgraded, forcing the closure of an entire section for three days in November.

Another project: the Saint-Michel-Notre Dame station is undergoing a comprehensive renovation of its spaces, and in particular the platforms impacted by infiltration. The first stage of the project is the replacement of the seepage drainage system, as the station is located close to a water table.
