RER A Summer work

All change for summer works in 2019

Since 2015, as part of the work to renew tracks and ballast in Paris, RER line A has been closed for 4 consecutive weeks each summer. In 2019, that is changing!

RER line A will be closed between Auber and Vincennes:

  • every evening and weekend from 13 July to 9 August inclusive,
  • all day from 10 to 18 August inclusive,
  • every evening and weekend from 19 August to 1 September inclusive.

Over 325 million passengers each year
RER line A has been operating for over 40 years with ever-increasing passenger numbers: at rush hour in Paris today, RER line A trains run every 2 minutes 20 seconds, carrying up to 65,000 passengers an hour in each direction. Each year, the line carries over 325 million passengers, the equivalent of the population of the United States!

With such a high flow rate, track and ballast renewal work in the most-used central section of the line is essential. Thus, works have been carried out over the course of previous summers: in total, 15 kilometres of track have already been renewed and 10 points replaced. By 2021, at the end of the project, a total of 24 kilometres of track and 28 points will have been changed.


New work area, new rhythm!
This summer, work is moving to the area between Auber and Vincennes:

  • During the closure periods, trains will terminate at Auber station and Vincennes station (both stations will remain open and connections will be maintained), while RER line A platforms at Châtelet-les-Halles, Gare de Lyon and Nation will be completely closed.
  • Outside these closure periods, trains will run between these stations as normal, though with some delays to be expected due to stabilisation of the tracks after each night’s work.
