RER B to CDG running from stops before Gare du Nord (eg Luxembourg) on strike days? We hope to travel to CDG Monday April 16 (from Lux. during rush hours). Not a strike day at this point, but just in case....
We'll have to wait until SNCF announces train strike action on Sunday for Monday April 16, 2018. Please keep checking with the Paris RER Train strike page for updated information.
If strike action does impact the RER B on April 16, 2018, you will need to switch RER B trains between Luxembourg and Gare du Nord. Upon arriving at Gare du Nord you will need to go to the Grandes Lignes surface trains, lanes (voies) 30-36 and find the next RER B train departing for Aeroport CDG 1/2 from there.
