Hi. I read a post on a Disney Facebook page from someone claiming that the RER A line was having work done from late July through mid-August 2022, and that anyone planning on going to Disneyland during that timeframe would have to get there using some form of transportation other than the RER. So I went online and searched, but I couldn't find anything about this supposed work. Does anyone know if this is true, or is it incorrect? I don't relish the thought of having to rent a car or pay UBER over 100 euro when my weekly Navigo will get me there just fine. Thanks!
There's no mention of RER A interruptions (on the Marne La Vallee end of the line) due to construction work in July - August 2022. Not on the RATP site, not on the Transilien site, not on the RER A blog: (you'll have to Google Translate these pages, they don't offer them in English)
For the Transilien website, check out the section for "L'info trafic en temps réel", click RER, click "PERTURBATIONS A VENIR", this is the list of construction closures. All of them are on the western end of the RER A line (Cergy/Poissy), the end opposite of Marne la Vallee (where Disney is located).
The last link above is a construction works calendar for the RER A line. There is construction, but none interrupting traffic between Paris and Disneyland. All line works are being done on the western branches of the RER A line, out in the suburbs of Nanterre, Sartourville, etc.
