RER A Summer work
To better understand the 2017 summer closure
This summer, the RER A track replacement work will lead to a total closure of the RER A line between La Défense and Nation from July 29, to August 27 inclusive.

Therefore La Défense and Nation will become temporary terminus (stations will remain open and connections will be operated), whereas RER A train platforms will be entirely closed at Charles-de- Gaulle-Etoile station, Auber station, Châtelet-les- Halles station and Gare de Lyon station.
