État de la PC : an RER C works base on the Petite Ceinture… served by rail !
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.
