Modernization work: major disruptions on the RATP and SNCF network this weekend

Necessary to modernize the network, the work is often concentrated on weekends and school holidays to minimize their impact on users. These September 19 and 20 are no exception to the rule, with a peak expected on Sunday September 20: two metro lines will be completely closed in Paris, as well as certain branches of the RER and Transilien.

These include metro line 6, completely interrupted on Sunday for “modernization work”, warns the RATP. Replacement buses will run but only between Charles-de-Gaulle - Étoile and La Motte-Piquet - Grenelle. Bus 71, which partly follows the line between Nation and Bercy, is reinforced. Line 13 will also be completely closed this Sunday to prepare for the arrival of future MF19 trains (in summer 2027) and automation by 2035. These two lines must still be closed on several Sundays until the end of the year.

The RER C does not run at weekends on the Pontoise branch from Champ-de-Mars station. On Sunday, it will also be interrupted between Paris Austerlitz and Dourdan and Saint-Martin-d’Etampes. Replacement buses are offered. As for the RER E, it is interrupted all weekend between Nanterre - La Folie and Le Plessis-Trévise, to allow the preparation of the connection with the future line 15 at Rosny - Bois-Perrier station. Trains, however, run between Nanterre and Chelles - Gournay, as well as between Le Plessis-Trévise and Tournan. Finally, the Transilien H is interrupted all weekend between Ermont - Eaubonne and Épinay - Villetaneuse.
