- Will March 2023 train strikes or potential strikes affect the RER and Metro lines?
I am arriving 3/20 am and departing 3/26.
There's potential the Paris workers strikes will affect both the RER and Metro. We won't know till shortly before whether any action will take place on March 20 (as in 1-2 days prior). For example there's strike action planned for March 7 and that information was published on March 5.
Normally strikes don't completely stop service, rather, reduce the frequency. So one can expect fuller train cars and longer wait times, but service is still available.
