SNCF specified Wednesday evening the expected level of impact, more marked in the regions and in Île-de-France than on high-speed services.
These disruptions are linked to the interprofessional industrial action initiated by the unions to defend wages and purchasing power.
Passengers should check in advance, as forecasts are updated on official mobility channels.
On the main lines, disruptions are expected to be minor: one TGV in ten will be cancelled.
All traffic forecasts, detailed line by line, are available from 5 p.m. this Wednesday on mobility websites and apps. The interprofessional strike planned for Thursday, November 5, explains these traffic forecasts.
