SNCF Réseau, the French national rail network operator, is carrying out major track modernisation work on the Paris - Le Creusot TGV - Mâcon Loché TGV - Lyon high-speed line between Vergigny and Sambourg (89).

SPECTACULAR WORK ON THE BUSIEST FRENCH RAILWAY LINE

The modernisation of the track on the Paris - Le Creusot TGV - Mâcon Loché TGV - Lyon high-speed line, which began in 2020 and will be completed this year, represents an investment of more than €300 million financed by SNCF Réseau over about 160 km of track.

A first phase of work took place in 2020 between Vergigny and Tonnerre, enabling 64 kilometres of track to be renewed.

A second phase of work took place in 2021 between Sarry and Thoste, and a third phase of track modernisation was carried out in 2022 in the Yonne, between Sambourg and Châtel-Gérard, which renewed 30 kilometres of track.

  • For 2023, the work will be concentrated between Vergigny and Sambourg, representing an amount of 48.9 million euros financed by SNCF Réseau
  • In total, 32 kilometres of the track will be renewed in this area representing 54,000 sleepers and 10,000 tonnes of ballast
  • 350 SNCF agents and a group of companies will be mobilised on this large-scale project
  • The work will be carried out at night from 10 pm to 6.30 am, from Monday evening to Saturday morning, from 9 January to 27 May 2023, sometimes extending the journey time of certain trains and adapting their timetable.

THE WORKS TRAIN, A REAL FACTORY ON RAILS

The work is carried out using a 750-metre-long factory train that can weigh up to 2,500 tonnes. This train is made up of a succession of machines that enable the track components to be renewed.

While conventional methods only allow for the renewal of 200 metres of track per day, on this site, more than 500 metres of the track will be replaced on average each night and up to 700 metres on certain nights thanks to this spectacular train.

This industrial method makes it possible to reduce the overall duration of the work while preserving the line's performance and regularity for passengers during the day.

A WORKSITE SYNONYMOUS WITH LOCAL ECONOMIC AND SOCIAL BENEFITS

This project, which involves an average of 350 workers and ten companies, indirectly generates economic benefits linked to the accommodation and catering of site personnel. It represents the equivalent of 225 direct jobs and 188 indirect jobs over one year.
