It’s the most-used RER line in the Île-de-France region! With an average of 309 million passengers per year, the RER A is the busiest line in Europe. It serves over 40 stations, enabling millions of passengers to get around. Ridership continues to rise year after year, which inevitably requires some adjustments. To ensure everyone’s safety,the line will undergo various construction projects on different sections . And these projects are already underway…
The RER A will be partially closed for 32 days: find out the dates
As you know, from this April through the end of June, the RER A will undergo various renovation works. Indeed, some tracks have been particularly damaged by the train’s frequent passage, and it was important to replace them. As with the République station, water leaks are threatening the RER A tunnel. Nighttime work will seal the arches and thus prevent short-circuit issues.
A major construction project affecting various parts of the line. Here are the details:
- The section between La Varenne-Chennevières and Boissy-Saint-Légerwill be closed starting at 9:45 p.m. through April 30. A total closure of the end of the line, with replacement buses… but which doubles the travel time.
- The section between Maisons-Laffitte and Cergy-le-Haut will be closed starting tonight through April 24, then from April 27 to 29, beginning at 9:50 p.m.
- From Nanterre-Préfecture to Cergy / Poissy, every Friday night in June starting at 10 p.m., don’t count on the train to get you home
- A complete suspension of service on the line between Nanterre-Préfecture and Cergy-le-Haut on the weekends of June 6–7, June 13–14, and June 27–28
- Closure of the section between Auber and Nation on Saturday, May 2, starting at 10:45 p.m.
- Nation station will be closed all day on June 29 and 30. Connections between Metro lines 1, 2, 6, and 9 will not be possible
Please note that all sections affected by these changes will have replacement buses to ensure you can get where you need to go . It’s the lesser of two evils, even though, as we know, the buses will inevitably be slower…
