//Complete upgrade of the line from Nice to Plan du Var

The line dating from between 1890 and 1911 was built in metre gauge and runs through five mountain valleys, traversing some 60 viaducts and tunnels along the way. It is one of the most beautiful and impressive railway lines in France. Owing to the poor condition of the line, the operating company, Région Provence – Alpes – Côte d’Azur, placed a contract for the complete renewal of the section from Nice to Plan du Var.

The Sersa Group was awarded the contract on the strength of its extensive experience throughout Europe and proven expertise in metre gauge track systems, as well as the professional expertise the company demonstrated during the "Puy de Dôme" project.

The section to be renewed was divided into three sub-sections, which were closed to traffic during the active project phase.
