Major maintenance work on the line, mainly on the track and the railway structures, is planned. To complete the work in the best possible way, with minimal impact on railway operations, it will be completed in three stages:
- Creation of two cross-overs at Satigny
- Maintenance work on the line between Satigny and La Plaine
- Maintenance work on the line between Satigny and Vernier-Meyrin-Cargo.
The installation of the cross-overs at Satigny is a necessary first step for carrying out future work to renew the line since this will facilitate rail traffic during the different phases of the work.
The project consists mainly of the following work:
- Replacement of rails, sleepers and ballast
- Installation of two cross-overs
- Heating of two cross-overs
- Installation of contact lines
- Installation of safety installations
- Installation of a new drainage system.
