On December 12, train services in Île-de-France will be disrupted due to a strike called by the CGT-Cheminots and SUD-Rail unions, protesting the dismantling of Fret SNCF and the opening up to competition. The most affected lines include the RER D and Transilien Line R, with varying levels of service disruption across other lines. The strike is anticipated to have limited impact overall, as other major services are running normally thanks to agreements made with different unions.
