Need your help!
I plan to go with my mom to Versailles on September 20th (2018). We plan to take the train from Saint-Michel-Notre-Dame station and arrive to Gare de Versailles Chateau rive Gauche station. I know that currently RER C is under construction, and the different works (hopefully) are scheduled to end on September 2nd. However, when I enter my date of departure and the stations for my route in Google Maps it says :"! Modified Service". Does it mean that the traveling time will be longer or there will be no possibility to take that train because of construction? Thank you in advance! I appreciate your help!
RATP route planner shows that your St. Michel-Notre Dame to Versailles Rive Gauche trip will work fine on September 20.
