News monitoringRER A — Cergy-le-Haut / Poissy ↔ Marne-la-Vallée–Chessy / Boissy-Saint-Léger
The RER A is the busiest suburban line in Europe, carrying well over a million passengers a day, and it is jointly run by RATP and SNCF. That dual operation matters during strikes: a purely RATP walkout can leave the central section running while the SNCF-operated western branches to Cergy and Poissy are cut, or the reverse.
What a strike means on this line
The RER A is operated by RATP and SNCF, so it is affected by both RATP and SNCF strike notices — sometimes only one half of the line stops. On a strike day expect outer branches to be suspended first, with a reduced service maintained on the central section.
Key stations on the line
- Cergy-le-Haut
- Poissy
- La Défense
- Charles de Gaulle–Étoile
- Auber

Alternatives during a strike

- Line 14 + RER E — For Marne-la-Vallée, change at Gare de Lyon or Haussmann-Saint-Lazare.
Frequently asked questions
Is the RER A running today?
The live panel above answers this for right now — it is refreshed every 30 minutes from official PRIM data. The RER A runs between Cergy-le-Haut / Poissy and Marne-la-Vallée–Chessy / Boissy-Saint-Léger, and during strikes the outer branches are usually cut before the central Paris section.
Who operates the RER A and why does it matter for strikes?
The RER A is operated by RATP and SNCF. That determines which strike notices apply to it: a purely RATP action can stop one part of the line while the SNCF-run branches keep going, and vice versa.
What is the best alternative when the RER A is on strike?
Métro line 1 — Driverless and parallel between La Défense and Nation — the standard fallback for the central section. If that is also disrupted, transilien l or j is the next option: From Saint-Lazare toward the western suburbs when the Cergy/Poissy branches are cut.
Are there planned works on the RER A?
No major closure is currently listed for the RER A beyond routine night-time engineering work. Planned works are shown as an amber notice on this page whenever one applies.
