How do you carry out work on the electricity network when it crosses a railroad line? To answer this question, which involves both technical issues and controlling the impact on passengers, Enedis and SNCF Réseau Hauts-de-France have signed a partnership agreement. The first concrete application is an unusual electrical upgrade project at Rang-du-Fliers: Enedis teams and their contractor, Coquart, drilled a hole to pass a 20 kV high-voltage cable under the railroad line. The work took place over three nights, from May 31 to June 2, to preserve rail traffic.

Every year, Enedis plans to modernize its electricity network. These projects are part of the company's investment program to strengthen the network's resistance to climatic hazards, extend the lifespan of its structures and thus improve the quality of electricity supply. The Rang-du-Fliers site was identified for the renewal of a medium-voltage power line.

During the nights of May 31 to June 2, Enedis teams and those of its service provider worked to carry out the directional drilling to pass the power line under the SNCF lines.

As the power line passes under the busy Calais-Paris line, careful coordination between SNCF Réseau, Enedis, and its contractor was essential to ensure that the work could be carried out safely, while limiting the inconvenience to users and residents. This coordination between the two network managers, electricity and rail, has been formalized to apply to all joint work sites between SNCF Réseau and Enedis. Nathalie Darmendrail, territorial director of SNCF Réseau Hauts-de-France, and Thierry Pagès, regional director of Enedis Hauts-de-France, have signed a partnership agreement. It aims to improve cooperation between the two companies:

  • by better sharing the issues and priorities in the Hauts-de-France territory of each company
  • by coordinating and anticipating the realization of large-scale operations requiring the crossing of railroad tracks by Enedis lines (connections of industrial or tertiary sites, network restructuring etc.)
  • by setting up special contacts in charge of the overall monitoring of these projects.

Key figures of the project

  • 6 people mobilized
  • 6 hours of emergency intervention each night
  • 3 nights to preserve rail traffic

"Enedis and SNCF RESEAU are committed players in their region, fully aware of the Hauts-de-France region's priorities in terms of economic development, regional planning, and ecological transition. With this partnership, our common objective is to facilitate and secure the execution of Enedis' worksites, by avoiding or limiting rail slowdowns and anticipating the worksites of each company. We are affirming our desire to strengthen our cooperation for the ultimate benefit of our customers," said Nathalie Darmendrail, territorial director of SNCF Réseau Hauts-de-France.

"Customer satisfaction is a major issue for both SNCF Réseau and Enedis. This agreement will enable us to simplify exchanges between our respective teams in the service of our two companies' customers," comments Thierry Pagès, Regional Director of Enedis Nord-Pas de Calais.
