This summer, from 26 June to 29 August, there will be closures on the western side of the RER A to allow for engineering works.
But on which days will they take place ?, At what time on the Poissy or Cergy branch ? Which stations will be affected ? How to get around the closures ? How to get your connection ?
You probably have a lot of questions that we try to answer! And even better, you can take our answers with you wherever you go, in paper or digital format.
The practical summer guide of RER A engineering works is available at all RER A stations and at some metro stations. All the information you need can be found in this guide (schedule of closures, impacted sections, metro plan, neighbourhood plans and replacement lines, practical tips, etc.). One side of this guide is intended for Anglophones and foreign travelers (Spanish, Italian, German). To put in every pocket ?
