This summer, the RATP enjoys a lower user number to carry out renovations on railways. For the summer 2022 renovations, RER A’s traffic will be interrupted between La Défense and Auber stations between August 13 and 19, 2022, namely 7 days. Here is more on the matter.

Every summer, modernization works continue on RER A. This year, the traffic is interrupted because of the renewal of the signal station. The goal? Entirely replace the station existing since the RER A started in 1970, to enjoy new technologies.

But these renovations do not go without consequences and will lead to passenger service shutdown. Therefore, between August 13 and 19, 2022 included, the RER A will be closed 24/7 between Auber and La Défense stations.

The RATP specifies other lines will be reinforced and alternative routes will be proposed to RER A users, namely:

  • Line 1 – enabling to go through the interrupted area this summer, from La Défense to Châtelet – Les Halles, whilst serving Charles de Gaulle – Etoile.

  • Users on the Saint-Germain-en-Laye / Cergy / Poissy branch towards Auber will use:
    • Whether Line L Nord between Cergy-Le Haut and Paris-Saint-Lazare
    • Or Line L Sud between La Défense and Paris-Saint-Lazare

Furthermore, no train will ride on RER A between Nanterre-Préfecture and Cergy – Le Haut / Poissy on August 13 and 14. This time, the traffic interruption is to allow the renewal of turnout sleepers in Sartrouville.

There again, reinforcements and alternative routes are planned:

  • Users of the Cergy / Poissy branches can use the Line L Nord between Paris-Saint-Lazare and Houilles or line J between Paris-Saint-Lazare and Conflans-Fin d’Oise.

  • Alternative buses will be provided between Houilles-Carrières-sur-Seine and Poissy, and rail shuttles will be available between Poissy and Cergy-Le Haut to continue the commute.

  • Poissy commuters can use RER A departing from Saint-Germain-en-Laye using bus 24 that will be reinforced.
