During my research of Musee D’Orsay station on RER C line I am getting conflicting info as to presence of escalators and/or elevators. Plan to take RER C in both directions all the way to Versailles on one trip and to Dourdan on another. On the Ratp accessibility map it lists the station as access by stairs only, up to 2 flights below ground. When I google info about it I get that it is accessible by both escalator and elevator. Don’t know if the RATP site is not updated?? So I am looking for anyone that has very recent actual use/ knowledge of the accessibility of Musee d’orsay station! Thank you for all your input!

I don't know what that app shows but RER C is not run by RATP, it is run by SNCF. Transilien website says all 3 elevators are working and 5/7 escalators.

Thanks for the info! I have gotten confused now that the same tickets can be used for both the metro, buses and RER.
Always why I love reaching out on Fodor’s!
