New Provence-Côte-d’Azur railway line

Reducing congestion at the Marseille, Toulon and Nice rail hubs

The Provence Alpes Côte d’Azur region is facing saturation of its road networks, worsened by the insufficient infrastructure of its rail network. The new Provence Alpes Côte d’Azur line (LNPCA) project involves improving this rail network to facilitate daily travel between and within the region’s major cities, and to create an efficient Mediterranean rail arc. Artelia is assisting SNCF Réseau with the implementation of this programme.


The current railway line linking Marseille, Toulon and Nice, which already serves more than 4 million people, has reached its limits and can hardly support the modal shift from road to rail expected by the authorities. The new Provence Alpes Côte d’Azur line (LNPCA) project aims to reinforce this network in order to increase rail services, improve journey times and offer users a more reliable and efficient service.

One of France’s biggest rail programmes, it will be carried out in 4 major phases up to 2050. Some parts of this programme focus on improving the existing regional express trains network, through a number of upgrades, while others involve the creation of additional tracks, structures and stations, which are essential in particular to open up the easternmost regions.

Artelia is involved at several levels of the project. Our teams provide strategic support to SNCF. They steer the concerted design of the operations and draw up the regulatory files. They also carry out various technical, socio-economic and environmental studies relating to the various operations planned.
