Ten metro lines will be totally closed:
2
3
3bis
5
6
7bis
10
11
12
13
The following lines will be partially open, only during rush hour:
4
7
8
The automated lines 1 and 14 will supposedly roll as normal (but I wouldn’t count on being able to squash yourself into one).
RER A: one train out of every three will run
RER B (within Paris): one train out of every five will run. No connection at Gare du Nord between the city portion of the RER run by the RATP and the suburban portion run by the SNCF.
Bus and tramway traffic also to be “very disturbed” with one-third of normal vehicles/trams running.
This one is a doozy.
