Throughout the year, RATP undertakes modernization work on the various lines of its network, whether metro, RER or tramway. This work will continue over the coming weeks, notably on metro lines 6, 9 and 14, and on RER line B. RER line A will also be affected. Régie Autonome des Transports Parisiens has announced.
As a result, disruptions are expected for users of the RER A line, which links Saint-Germain-en-Laye, Cergy and Poissy to the west, and Boissy-Saint-Léger and Marne-la-Vallée to the east, passing through the center of Paris.
So, what can we expect in the days and weeks ahead? In detail, RATP warns that no trains will run between Maisons-Laffitte and Cergy-Le Haut, from April 14 to 18, 2025, from 10:15pm. On Easter Monday, April 21, there will also be no trains between Maisons-Laffitte and Poissy, from 10.15pm.
Other disruptions are scheduled for April. For example, no RER A trains will be running between Sartrouville and Cergy-Le Haut / Poissy, from April 22 to 25 (from 10:15pm), then between Maisons-Laffitte and Poissy, in the evening, from April 28 to 30, 2025.
Note that other works are likely to disrupt RER A traffic in 2025. Stay tuned for the schedule of other upcoming closures and works.
