Paris Rail Strike Disrupts RER and Suburban Trains Today

Source-checked update: This article brings together information checked against primary sources and independent reporting available at publication time. Full source links are listed at the end of the article.

A national interprofessional strike is reducing service on several Paris-area RER and Transilien suburban rail lines today, Tuesday, September 29, 2026. The disruption is uneven across the network: some lines are running with fewer trains, while RER A and RER B are reported as operating normally.

For visitors, the main effect is a less predictable journey on affected routes, particularly when traveling between central Paris and suburban destinations. RATP has also confirmed that several metro stations are closed from noon because of a demonstration, adding another complication for travelers moving around the city during the day.

What Happened

The strike is affecting Paris-area public transport on Tuesday, September 29. Transilien reports disrupted service on suburban lines C, D, E, R and V, and advises travelers using affected lines to limit travel where possible.

The extent of the disruption varies by line and, in some cases, by section. RER C and RER E are operating at approximately three trains out of four. RER D is more severely affected, with service ranging from one train out of two to one train out of three depending on the section.

Transilien line R is running at approximately one train out of three on affected sections. Line V is operating at around two trains out of three. RATP describes line R as heavily disrupted because of the national interprofessional strike.

The disruption does not cover the entire RER network. RER A and RER B are reported as operating normally, although travelers may still need to make connections with affected lines or use stations impacted by the demonstration-related closures.

The confirmed disruption applies to Tuesday, September 29. No reliable end date has been established, so travelers should not assume that service will return to normal at a specific time beyond the information published for today.

What This Means for Travelers

Anyone relying on RER C, RER D, RER E, Transilien R or Transilien V should expect reduced service and potentially longer waits. Trains may be less frequent than usual, and the effect can differ between sections of the same line. A route that appears available in one part of the network may therefore be more difficult farther along the journey.

RER D users face the most significant reductions among the affected RER lines, with frequencies varying from half the normal service to one train in three. Travelers using lines R and V should also allow additional time, particularly where their journey depends on the affected sections.

The strike may be especially inconvenient for visitors traveling between Paris and suburban areas, or for those planning tightly timed connections. Reduced rail frequency can make missed connections more likely, while the closure of several metro stations from noon may require travelers to reconsider how they reach or leave parts of the city.

This is reduced service and heavy disruption on specific routes, not a complete shutdown of every RER or suburban train. However, normal operation on RER A and RER B does not guarantee that an entire journey will be unaffected if it involves another line, a transfer, or a station closed because of the demonstration.

What Travelers Should Do Now

Check the latest information directly with RATP or Transilien immediately before leaving and again before making a return journey. Service levels can vary by line and section, so travelers should check the specific route rather than relying only on a general network update.

If travel on an affected line is necessary, allow extra time and avoid scheduling a tight connection where possible. Transilien advises travelers to limit journeys on the disrupted lines where they can, which is particularly relevant for nonessential trips during the strike.

Review the full journey, including transfers. A normally operating line such as RER A or RER B may still connect with an affected service, and a metro station closure from noon may alter the most convenient way to reach a station. Confirm station access and service status before setting out.

Travelers who are unsure whether their journey is feasible should check directly with the relevant transport operator before departure. Because no reliable end date has been established, anyone traveling beyond Tuesday should verify conditions again rather than assuming that the same service pattern will continue—or that normal service will have resumed.
