Réseau Ferré de France – Renovation of tracks between Paray le Monial and Montceau les Mines

The French railway network RFF wished to modernise the railway line located in the department of la Côte d’Or, and connecting Montceau les Mines to Paray le Monial. This 36-km line is on non-electrified double railtrack.

The main objectives of the task are:

  • Reinstate the line’s original rail speed,
  • Increase this speed when the geometry so permits.

This study related to:

  • 3 multi-span stone viaducts,
  • Several stone walls and riprap,
  • 2 earthworks that support the railway line,
  • Various single-span concrete and stone structures with modest apertures (of approximately 1 m to 20 m).
