A mixed assessment. The organizing authority for public transport in the Ile-de-France region, Île-de-France Mobilités (IDFM), has just announced that users of no less than 15 rail routes will be able to be reimbursed for “half a month of Navigo pass” under punctuality results in 2023. IDFM, however, emphasizes having observed “a first recovery since the start of 2024”. Among them, four axes of RER B, five axes of RER C and three axes of RER D as well as two axes of line P.

Each year since its implementation in 2021, this compensation is triggered “in the event of punctuality less than 80% for at least 3 months, in the event of long-term strikes or exceptional disruptions”. This year, the president of IDFM, Valérie Pécresse, decided to “be even more demanding”, by compensating users living or working on a route whose annual punctuality is less than 85%.

Result, taking this calculation into account, 4 additional axes are concerned. Among which, the Cergy-le-Haut-Maisons-Lafitte axis on the RER A, the Massy-Les Saules axis on the RER C, as well as the two axes Montgeron-Combs-la-Ville and Vigneux-Corbeil via the Plateau on the RER D. To be reimbursed, each user concerned will need to request it on a dedicated site which will be put online at the end of March. Knowing that the amount of compensation will amount to “between half a month of Navigo package” and could even reach “a month and a half for the RER B axis located between Aulnay and Mitry-Claye”, specifies IDFM.

This is a big new thing this year, late cancellations – that is to say “train cancellations the day before 5 p.m. due to lack of drivers” – will now be “taken into account”, at the request of IDFM . “Until now, these deletions did not appear in the figures communicated by the SNCF because the trains canceled the day before 5 p.m. do not appear in the SNCF systems,” the authority defended on this subject.

However, “certain branches which in certain months appear slightly above 80%, fall back below 80% after taking these deletions into account”, and are therefore now “subject to compensation”, explains IDFM. This is particularly the case of the RER C, whose punctuality suffered greatly from these deletions in 2023, and the P line to a lesser extent, specifies the authority, which points out that “in December 2023, these are nearly 15% of RER C missions which were canceled due to lack of drivers.
