Transport in Paris and Île-de-France: Metro and RER disruptions from August 31 to September 6, 2026.

Subway, RER, and Transilien services remain disrupted in Paris and Île-de-France for this back-to-school week, from August 31 to September 6, 2026, as several RATP and SNCF worksites continue across the network. Here's everything you need to know.

The return to routine does not yet spell the end of disruptions in Île-de-France transport. After the major travaux menés pendant l'été, several work sites continue on the networks of the RATP and the SNCF, in Paris as well as in the départements of the inner and outer rings. Metro, RER, Transilien or tram: some travelers will therefore still have to adjust their journeys this week, from Monday August 31 to Sunday, September 6, 2026. We break it down line by line.
