SNCF has announced schedule adjustments for the RER D on the branch connecting Melun to Corbeil Essonnes. These changes, which will apply only on weekdays, will run from Monday, October 19 to Friday, November 13, 2026.
These adjustments aim to better manage occasional slowdowns that can occur on this line during the autumn season. The goal is to prevent train cancellations and ensure better service regularity.
For more details on the phenomena of slipping and skidding that explain these measures, a blog post is available online. Travelers can check the updated schedules now via SNCF's digital tools, such as the IDFM app, the transilien.com website, SNCF Connect, or their usual mobility application.
