Nîmes-Montpellier HSR Rail By-Pass
The Nimes-Montpellier rail by-pass is a ground-breaking project. It’s the first high speed line in France to be specifically designed to handle “combined” passenger/freight traffic in France.
SYSTRA was a member of the OC’VIA Consortium, which won the HSL design and construction contract. SYSTRA was in charge of integrated project management, with SETEC. Its activities included:
- Preliminary technical designs and feasibility studies (infrastructure and superstructure),
- The design of the new line, freight links and connections to the national railway network,
- Management and follow-up of administrative issues and associated procedures,
- Safety management, verifying all changes made to civil engineering designs and railway equipment,
- Management of Reliability, Availability and Maintainability activities during the design phase,
- Interface management,
- Configuration and documentation management,
- Technical and quality inspection of infrastructure construction work and railway equipment,
- Testing assistance, excluding pre-operation testing activities.
The Nimes-Montpellier high speed rail by-pass comprises a number of innovative features, particularly with regard to the infrastructure: the track bed comprises a bituminous sub-ballast layer, sensors to identify the impact of cross-wind speeds on both passenger and freight trains and a V220 => V300 power converter.
