Grand Paris Express Line 14
_ Rail works. Business activity in connection with the national rail network was spread over numerous maintenance and modernisation projects, which included a rail bypass at industrial sites in Donges (western France), putting in new catenaries between Tarbes and Montréjeau (southern France) and renovating the platforms in Gare de Lyon in Paris.
Over the year, 252km of track were fully replaced thanks to the use of two high-output track renewal trains. Several urban projects were also carried out as part of the Grand Paris Express programme: work on the northern (1.5km) and southern (14km) extensions to Line 14 was completed, while work began on the future south-western Line 15 (16.5km) between Boulogne-Billancourt south-west of Paris and Vitry-sur-Seine south of Paris, in synergy with VINCI Energies. Teams also provided maintenance for private rail networks in the ports of Marseille and Nantes-Saint-Nazaire and a number of major industrial sites.
