How do I report a defect in rail rolling stock (train, metro, tram)?
To enable the operator concerned to act as quickly as possible on the network it operates, it is necessary to report directly to it any anomaly concerning the rolling stock: the day, the time, the line, the type of equipment concerned, the station, etc.
QR codes are available on trains (in the form of stickers) to allow reports to be made on comfort and cleanliness conditions.
