Between late March and early July 2026, line L experienced significant disruptions due to a rail defect that damaged the wheels of several trains. Some trains were notably mobilized as reinforcements on line J, thereby reducing the number of services on line L.
Given the scale and duration of these disruptions, Île-de-France Mobilités has established a compensation campaign for affected passengers on lines J and L. Eligibility conditions depend on your situation, your subscription, and the stations or municipalities concerned.
The reimbursement platform is open until October 13, 2026, at 11:59 PM. You can check your eligibility and submit your request directly online on the Île-de-France Mobilités platform.
For those who have already submitted their request, it is also possible to track its progress in the dedicated area.
Île-de-France Mobilités thanks passengers for their patience and acknowledges the difficulties encountered in recent months, reaffirming its commitment to addressing them.
