RER C.
Small lull in the maintenance work program for line C this weekend.
The only disruptions to be expected are the cessation of rail traffic, Sunday evening after 10 p.m. on the Etampes-Austerlitz and Dourdan-Austerlitz branches and direct trains between Juvisy (Essonne) and Choisy-le-Roi (Val-de-Marne) throughout the weekend.
The Athis-Mons, Ablon and Villeneuve-le-Roi stations not served by train are accessible by regular bus lines.
RER D.
Beware of section closures.
Saturday and Sunday all day, traffic will be interrupted between Creil and Goussainville to the north and between Gare de Lyon and Juvisy-sur-Orge to the south.
A replacement bus service is being set up on the entire northern section under construction and between Juvisy and Villeneuve-Saint-Georges for the southern branch.
RER
E.
Early evening closures on the various branches of line E. Saturday and Sunday, rail traffic will be interrupted from 10:15 p.m. on the Haussmann-Chelles/Gournay axis and after 10:30 p.m. on the Villiers-sur-Marne/Tournan axis.
The replacement bus service from Chelles (Seine-et-Marne) towards Paris will terminate at Gare de l'Est.
In the opposite direction, it will leave from Bobigny-Pablo Picasso station (Seine-Saint-Denis) on line 5.
Line J.
The rail link between Saint-Lazare and Mantes-la-Jolie (via Poissy) in Yvelines will be interrupted from 9:40 p.m., Saturday and Sunday evening.
Two replacement bus services (between Sartrouville and Les Mureaux and between Sartrouville and Mantes) are in place beyond this timetable.
Line N.
Line N trains are not running this weekend between Montparnasse, Versailles-Chantiers and Rambouillet in Yvelines.
Trains to Dreux are maintained but in omnibus configuration.
Their departure station is Versailles-Chantiers which remains accessible by RER C or line U. During the closure, line U is exceptionally extended to Rambouillet and its traffic is reinforced.
Line R.
Traffic will be interrupted between Melun and Montereau via Moret in Seine-et-Marne on Sunday from 12:30 a.m.
A replacement bus service will be put in place, serving intermediate stations.
Metro 11.
To go from Châtelet to Mairie des Lilas in Seine-Saint-Denis (or vice versa), you will have to take the bus this weekend.
Due to preparatory work for its extension (to Rosny) planned for next June, line 11 will be completely closed on Saturday and Sunday.
A substitute shuttle, serving all stations on the line, is set up at the same times as the metro.
Metro 14.
Work is intensifying on the eve of the extension of the “Olympic line” which must take place next June.
Consequence: the automatic line is once again completely closed to travelers throughout the weekend.
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.
