A mid-life renovation project

After twenty years of service, the trains undergo a so-called "mid-life" operation to be dismantled, renovated and modernised.
The aim is to be able to operate them again for another twenty years, with a virtually new state of repair and the same level of comfort and reliability.

The aim is to improve the energy consumption of the renovated trains, with a view to protecting the environment and ensuring the durability of the equipment.

Up to 55 trainsets are immobilised simultaneously in our industrial technical centres during mid-life refurbishment operations.

At the service of the Regions, organising authorities

In addition to these refurbishments, the Regions can take advantage of the opportunity to request other adjustments to their trains:

improving aesthetics and passenger comfort (changing seats, lights, regulating air conditioning, adding waste sorting bins, etc.);
the reorganisation of interior spaces to allow more space to be taken on board or improved accessibility (disabled access areas, areas dedicated to transporting bicycles, etc.);
installing electrical sockets on seats, Wi-Fi, or integrating an on-board passenger information system.
