Paris Metro, RER and Transilien passengers face evening suspensions from September 30 through October 2, followed by weekend closures on October 3 and 4 that shut Metro Line 6 for all of Sunday, October 4. The line by line forecasts, published September 29 and built from RATP and Transilien SNCF operating notices, also suspend late service on the RER A, B, C, D and E and on eight Transilien lines, with the airport corridors among the affected routes.
If you travel in Paris this week, check your route on the day and plan to finish late journeys early, because most suspensions start between 9 p.m. and 11:30 p.m. on weeknights. Travelers catching a late flight should review the CDG Paris Airport to Eiffel Tower transit guide before choosing between rail, Roissybus and Metro Line 14, since late night RER segments to both airports are among the suspended sections.
- Dates: Evening suspensions run September 30 through October 2, with weekend closures October 3 and 4, 2026.
- Biggest closure: Metro Line 6 is fully closed all day Sunday, October 4 for modernization work.
- Strike context: The September 29 national strike disrupted SNCF run lines including the RER C, D and E; RATP reported normal Metro, RER A and RER B service that day.
- What to do: Check the Ile de France Mobilites, RATP or Transilien SNCF planner on the day of travel and allow extra time after 9 p.m.
Evening Suspensions Hit the RER Network September 30 to October 2
Five RER lines carry works suspensions on the remaining weeknights, mostly after 10 p.m. On the RER A, service stops between Nanterre Prefecture and the Cergy le Haut and Poissy branches from 10 p.m. each weeknight through October 9. On the RER B, service is suspended between Chatelet Les Halles and the Mitry Claye and Charles de Gaulle 2 TGV branches after 10:45 p.m. through October 1, which covers late airport runs tonight and tomorrow night.
On the RER C, traffic stops between Invalides and Juvisy from 5 p.m. daily through October 4, and late night service is suspended between Gare d Austerlitz and Juvisy from 11 p.m. through October 2. The Austerlitz to Pont de Rungis Aeroport d Orly section is suspended from 10 p.m. through October 2, so evening travelers to Orly should use Metro Line 14 from central Paris instead. Between Saint Quentin en Yvelines and Javel, and between Versailles Chateau Rive Gauche and Javel, traffic is interrupted from 9:17 p.m. through October 2.
On the RER D, service is suspended between Gare de Lyon and the Melun and Corbeil Essonnes branches from 11:15 p.m. on weeknights through October 2. On the RER E, weekend traffic stays suspended between Villiers sur Marne and Tournan through November 1, and between Nanterre La Folie and Chelles Gournay from 10:45 p.m. on weekends through October 24. Full details appear in the Sortiraparis week long disruption roundup, which compiles the operator forecasts line by line.
Metro Line 6 Shuts All Day October 4
Sunday, October 4 brings the single largest closure of the week, with Metro Line 6 halted on its entire length for modernization work. Riders can use Metro Line 2 as a parallel route, since both lines run between Charles de Gaulle Etoile and Nation. The tradeoff is the loss of the elevated Seine crossing at the Bir Hakeim bridge, a favorite ride view, for the day.
Two longer Metro closures continue in the background. On Line 4, trains do not stop at Saint Michel through December 19, 2026 for renovation, although Odeon and Cite stay accessible. On Line 8, Republique station is not served through April 22, 2027, while Lines 3, 5, 9 and 11 still serve Republique. Visitors planning museum and sightseeing days can anchor plans with the ranked things to do in Paris guide and route around the closed stations in advance.
Transilien Lines Face Late Night Gaps Across the Suburbs
Eight Transilien lines carry evening interruptions, with the heaviest effects in Val d Oise, Yvelines and Seine et Marne. Several suspensions run only through tonight, September 30, including the Gare Montparnasse to Versailles Chantiers line from 11:40 p.m., the Dreux to Gare Montparnasse line from 9:55 p.m., the Plaisir Grignon to Mantes la Jolie line from 9:30 p.m. and the Gare Montparnasse to Rambouillet line from 11:35 p.m.
Longer running gaps continue into October. Between Ermont Eaubonne and Valmondois, service is suspended from 11:35 p.m. on weeknights through October 2. Between Sarcelles Saint Brice and the Luzarches and Persan Beaumont branches, service stops from 9 p.m. on weeknights through October 9. Between Issou Porcheville and Mantes la Jolie, service ends from 10:25 p.m. Monday to Friday through October 16, and between Saint Lazare and Mantes la Jolie via Poissy, service ends from 9:40 p.m. on the same days. Commuters in the far suburbs should check the Transilien SNCF planner before the evening return trip, since last departure times shift by branch.
How Airport Travelers Reach CDG and Orly Late at Night
Late flights deserve a backup plan this week. The RER B suspension between Chatelet Les Halles and Charles de Gaulle 2 TGV after 10:45 p.m. through October 1 affects the standard rail route to Roissy Charles de Gaulle, and the roundup points to the Roissybus, detailed on the RATP site, as the alternative for late arrivals and departures. For Orly, the RER C evening suspension between Austerlitz and Pont de Rungis Aeroport d Orly from 10 p.m. through October 2 makes Metro Line 14, which serves the airport from central Paris, the practical rail option.
Air travelers should also note the strike week context for flights. France’s civil aviation authority ordered a 5 percent schedule trim at Paris airports for the September 29 strike day, as covered in the Paris Charles de Gaulle flight cuts report. That order applied to the strike day itself, while the rail works described here run through the weekend.
What to Check Before Leaving the Hotel
Forecasts can change from day to day during a strike week, so verify the route on the morning of travel on the Ile de France Mobilites site, the RATP site or the Transilien SNCF site. Evening travelers should aim for departures well before the 9 p.m. to 11:30 p.m. suspension windows on their line, and weekend travelers should map alternatives now for the October 3 and 4 closures, especially the full day Line 6 shutdown and the RER C, D and E weekend segment suspensions.
The September 29 strike itself is now background, not the live disruption. Rail union SUD Rail called the September 29 walkout on September 9 after failed June wage talks, and seven public sector union federations joined a broader mobilization the same day, according to Finchannel reporting on the rail strike call. SNCF typically publishes its detailed traffic plan shortly before a strike, which is why the line level forecasts only firmed up on the evening of September 28. What remains live for travelers is the works program, not the strike.
| If you… | What to do |
|---|---|
| Travel after 9 p.m. on September 30 to October 2 | Finish the trip early or check the RATP or Transilien planner, since most suspensions start between 9 p.m. and 11:30 p.m. |
| Need Metro Line 6 on October 4 | Use parallel Metro Line 2 between Charles de Gaulle Etoile and Nation for the full day shutdown. |
| Fly out of CDG late at night through October 1 | Take the Roissybus instead of the RER B after 10:45 p.m. |
| Fly out of Orly in the evening through October 2 | Use Metro Line 14 from central Paris instead of the RER C evening segment. |
September 30 to October 2 evenings are the late night gate. Plan suburban and airport rail trips to end before 9 p.m. where possible, and confirm last departures branch by branch.
October 3 and 4 are the weekend gate. Map alternatives now for the Line 6 full day closure and the RER C, D, E and Transilien P, R, U and V weekend segment suspensions.
December 19, 2026 and April 22, 2027 are the long works gates. Line 4 skips Saint Michel until the December date and Line 8 skips Republique until the April date, so repeat visitors should keep routing around both stations.
Is the Paris Metro running normally on September 30?
Daytime Metro service runs, but evening works suspend late service on several RER and Transilien segments from about 9 p.m. onward. Check the RATP or Transilien planner on the day of travel.
Is Metro Line 6 really closed all day October 4?
Yes. Line 6 is fully halted on Sunday, October 4 for modernization work. Parallel Line 2 covers the same endpoints between Charles de Gaulle Etoile and Nation.
Did the September 29 strike shut the Metro?
No. RATP reported normal service across the Metro network and on the RER A and RER B on September 29. The strike hit SNCF operated lines, mainly the RER C, D and E and Transilien lines R and V.
How do I reach CDG airport late at night this week?
Through October 1, the RER B airport segment is suspended after 10:45 p.m., so use the Roissybus for late night CDG trips and confirm schedules on the RATP site.
