RER C.
Again and again infrastructure regeneration work leading to traffic interruptions to be expected this weekend, on line C. This Sunday, they will require the stopping of trains from 10 p.m. between Paris-Austerlitz and the southern terminus of Etampes and Dourdan in Essonne, from 11 p.m. on the Juvisy-Paris and Pont de Rungis-Paris routes, then at 11:30 p.m. between Versailles-Château Rive Gauche in Yvelines and Invalides.
Replacement bus services are scheduled.
Due to “preventative maintenance” work before the Olympics, the northern branch of line C will also be closed Saturday and Sunday all day between Invalides and Pontoise in Val-d'Oise.
RER D.
Throughout the weekend, the RER D departing from Paris will be non-stop from Gare de Lyon to Villeneuve-Saint-Georges in Val-de-Marne.
In the other direction, trains will be direct between Villeneuve-Saint-Georges and Maisons-Alfort.
A replacement bus service will provide access to intermediate stations not served by the RER.
RER E.
Pay attention to service changes.
Saturday and Sunday, line E trains heading to Chelles-Gournay, Villiers and Tournan in Seine-et-Marne will not stop at the Rosa-Parks and Pantin stations in Seine-Saint-Denis.
Rail traffic will also be interrupted from 9:45 p.m. Saturday and 10:30 p.m. Sunday on the Haussmann-Chelles Gournay axis as well as on the Paris-Tournan part.
Line J.
Saturday and Sunday (until 4 p.m.), trains will not run between Issou-Porcheville and Mantes-la-Jolie in Yvelines.
The rail link between Saint-Lazare and Mantes-la-Jolie (via Poissy) will be interrupted throughout the weekend.
A replacement bus service will be set up between Issou-Porcheville and Mantes.
Line K.
Traffic is interrupted, Saturday and Sunday, between Gare du Nord and Mitry-Claye in Seine-et-Marne.
To get around the "obstacle", take the RER B to Mitry-Claye then line K which operates normally to the terminus at Crépy-en-Valois in Oise.
Line N.
Line N trains are not running this weekend between Montparnasse, Versailles-Chantiers and Rambouillet in Yvelines.
Trains to Plaisir-Grignon and Dreux are maintained but have Versailles-Chantiers as their departure station which remains accessible by RER C or line U. During the closure, line U is exceptionally extended to Rambouillet and its traffic is reinforced (a train every 30 minutes).
Saturday and Sunday until 4:30 p.m., traffic will also be interrupted in both directions between Épône - Mézières and Mantes-la-Jolie.
Line P.
New round of works and disruptions on line P. On Saturday, trains on the Paris/Château-Thierry axis will stop from 10 p.m. then will be replaced by a bus service.

Metro 11.
No metro to expect this Sunday on line 11. Due to the preparatory work for the opening of the extension of the line (to Rosny-Bois-Perrier), it will be completely closed to travelers throughout the daytime.
A bus service serving all stations is set up
Metro 14.
Here we go again for the development work on the extensions of the automatic line (to Saint-Denis in the north and Orly airport in the south) which are due to open in just three months.
After a weekend without work last week, line 14 will again be closed along its entire length on Saturday and Sunday.
A replacement bus service is being set up between Gare de Lyon and the current southern terminus of the line, at Olympiades.
On the north side, the closure is likely to lead to traffic delays on line 13.
