As a nationwide movement is getting ready for tomorrow, announcements about disruptions in traffic are starting to come in from the SNCF and RATP. Between blockades and demonstrations, which metro and RER lines will be the most affected? We've got all the details for you!

At the start of the month of September, it's the end of vacation for everyone. For Parisians who are slowly finding their way back to work, as well as for the various unions and employees in France, who are loudly exercising their right to strike. And before gearing up again on September 18th, things kick off as early as tomorrow, with a national mobilization simply named « Block Everything ». But if everything is truly blocked, what can we expect in public transport tomorrow?


A Two-Speed Mobilization

Well, even though for the past few weeks, there's been a lot of buzz about a sort of apocalypse on September 10th, it seems that in reality, it might not be as disastrous as that. Indeed, the RATP announced on Monday, September 8th, very limited disruptions on the metro and bus network.

On the other hand, for the lines managed by the SNCF, buckle up, the journey might be a bit more bumpy. 4 lines will be heavily disrupted: the RER D and the Transiliens H, K, and R. The RER C and the RER B on its section operated by the railway company, along with the N and U lines, will also be "very disrupted", which is slightly less than the first ones, but still significant. Lastly, on the Transiliens L and J as well as on the RER E, only a few minor disturbances are expected.


A brief respite

However, while the RATP won't be as affected tomorrow as the SNCF or most airlines, it’s only a temporary relief, as the 4 main unions...

g>Public transport authorities have issued a strike notice for… next week! A “day of strike and massive demonstration” is set for Thursday, September 18, and even though no information has been revealed yet, we can imagine it will be much less peaceful right away. Get those pedals ready now, as your bicycle will probably be your best option!
