It's going to be a "black day" for public transport in the capital this Thursday, September 18. Indeed, while the 4 largest unions of the Paris transport authority are on strike, a number of lines and stations will face disruptions, even complete closures. Organizers are calling it a "historic" mobilization, which is likely to complicate your travels throughout the day.
Significantly disrupted lines
In detail, only three lines will run smoothly, namely the automatic lines: 1, 4, and 14. Unfortunately, it looks like things will be a bit more complicated for the others. Here’s the line-by-line breakdown.
Line 2: 1
train on 3, only between Nation and la Chapelle, from 6:30 AM to 10 AM and then from 4:30 PM to 7:30 PMLine 3: 1 train out of 5 between Pont de Levallois and Havre-Caumartin from 6:30 AM to 9:30 AM and then from 4 PM to 7:30 PM
Line 3 bis: 50% of trains will be running, but be careful, only between 2 PM and 7:30 PM
Line 5: 1 train out of 5 between Gare du Nord and Bobigny, from 6:30 AM to 9:30 AM and then from 4:30 PM to 7:30 PM
Line 6: 2 trains out of 5 from Nation to Place d’Italie (6:30 AM - 10:30 AM), and between Nation and Bercy (3:30 PM - 7:30 PM)

10 Stations Completely Inaccessible
On top of that, 10 stations will simply be closed throughout the day, with no services or connections available. And of course, we're talking about some of the busiest stations in the capital, or else it wouldn't be very funny, you must agree! This Thursday, it’s impossible to pass through Bastille, Concorde, Arts et Métiers, Villiers, Opéra, République, Trocadéro, Sèvres Babylone, Invalides, and Place de Clichy. There you go, now you know everything! We wish you lots of courage, and especially a maximum of remote work if you can!

Pas de métros, pas de trains, pas de bus, pas d’accueils dans les établissements, 90% des pharmacies fermées, pompiers en grève, blocages de routes et près d’un million de manifestants sont attendus !
C’est un gros mouvement qui se prépare demain #greve18septembre
