In July 2025, a new section of the Petite Ceinture ferroviaire opened to the public in the 15th arrondissement. Located near the Georges Brassens park, it extends eastwards the section opened in 2013 via the Vaugirard tunnel and enhances the site of the former abattoirs.
During the summer of 2025, a section of the Petite Ceinture Rive Gauche was used as a work base for one of the RER C construction sites. This type of traffic demonstrates the value of the line as a capacity reserve, in order to reduce the number of lorries on Ile-de-France roads.
In the run-up to the 2026 municipal elections, the fate of the Périphérique is crystallising passions. Candidates are vying with each other to come up with ideas to « break down » this concrete boundary, but one major structural solution remains in the blind spot : the Petite Ceinture.
