The SNCF and the RATP wish to improve transparency towards their users in the event of incidents on the lines. On the network, difficulties encountered are multifactorial, with many types of incidents.

These include passenger discomfort, technical incidents, malicious acts, or abandoned objects, which have multiplied fourfold in recent years. "When we are told "operating accident," people get annoyed and complain because they have the feeling of being taken for a ride," notes Arnaud Bertrand, president of the Plus de trains association. The lack of up-to-date, real-time passenger information that pushed users stuck on the train to Gare d'Austerlitz on March 18 is one of the reasons for the move, he says. The RER C was stopped due to a switch failure at Gare du Nord on February 18. In the event of a disturbance, the latter must broadcast an audible announcement within 3 minutes in the first impacted vehicle. SNCF Voyageurs wishes to continue improvement actions via the broadcast of economic messages live, on board and at the station, but also via station access screens. An application exclusively dedicated to railway works in the region, in order to inform users about upcoming disruptions. Due to the Olympic Games, IDFM will also generalize trilingual French-English-Spanish travel information, to guide visitors as best as possible. The screens of the 426 stations in Île-de-France can now now display the position of the next trains in real time, the remaining waiting time or even the level of attendance on board. The authority intends to use “concise reasons that are meaningful to travelers” instead of “material incident” rather than “social demonstration.
