Conducting rail projects

To offer a rail infrastructure achieving the ultimate in performance, SNCF Réseau carries out the modernisation works requested by the Government. Its goal is to meet the needs of customers and travellers while ensuring their safety. The works are performed in collaboration with local players, taking care to respect the environment.

A reliable, sustainable network for all uses

The works carried out by SNCF Réseau, as requested by public authorities, first of all comprise modernising existing rail lines (ex.: the Vigirail Plan accelerating the replacement of switches). The objective of all modernisation projects is to improve infrastructure accessibility, safety and reliability. They heighten traveller mobility and facilitate freight transport at the same time and are designed to have a limited impact on the environment. In this regard SNCF Réseau takes action and innovates to:

  • lower noise levels linked to its activities, primarily by installing noise barriers,
  • preserve water resources and biodiversity, for example by creating substitution ponds,
  • prevent flooding, specifically by installing stormwater collector networks,
  • harmoniously develop urban areas, based on promoting rail national heritage.

SNCF Réseau requires its representatives and service providers to apply the same principles regarding both innovation and social and environmental responsibility (SER). These principles are also respected for building new lines.

Rail projects suited to local needs

For each worksite, SNCF Réseau implements a qualitative procedure based on collaborating with local players (elected officials, local residents, travellers, etc.). Each operation is organized into three phases:

  1. The definition phase, during which local populations are consulted to incorporate their needs into the project. This primarily involves setting up citizens’ workshops (ex.: public consultations for building the new Montpellier train station).
  2. The design phase, during which the scheduled project’s economic, technical and environmental pertinence is checked. Its impact on any watercourses, for instance, is investigated.
  3. The works phase, which consists of effectively carrying out the works planned, both on budget and on time.
