LNSO: two successful blitz operations to modernise overhead lines
The weekend of 11 November marked a major step forward for the Ligne Nouvelle Sud-Ouest (LNSO) with the successful completion of two simultaneous blitz operations on the AFNT and AFSB construction sites. These operations mobilised more than 200 professionals in the field working on around 30 rail/road vehicles, most of which were hybrid. The teams from the ETF/INEO SCLE Ferroviaire consortium once again demonstrated their technical expertise and ability to mobilise resources.
AFNT: 56 hours of intervention north of Toulouse
At Saint-Jory station, work is progressing to improve suburban and regional traffic flow and prepare for the arrival of high-speed trains at Toulouse-Matabiau. This intensive operation has enabled 1.2 km of catenary lines to be upgraded to CS2R technology, a more sustainable and easier to maintain solution. Around 50 professionals have been mobilised for this third AFNT project, which is part of the framework agreement extending until the end of 2027.
AFSB: 62 hours of intervention south of Bordeaux
Further west, in Saint-Médard-d’Eyrans, our teams successfully carried out a new blitz operation as part of the AFSB project. During 62 hours of continuous work, 140 people were mobilised to migrate 5 km of catenary lines, or 4 spans, to CS2R technology. This advance brings the project to 55% overall completion, with the second successful blitz operation out of the five planned between now and November 2026.
Limiting noise impact with hybrid machinery
Hybrid machinery was used on both sites to reduce night-time noise pollution, an initiative that was particularly appreciated by local residents. This approach illustrates our commitment to combining technical performance with respect for the environment.
Thanks to the dedication of our teams and flawless organisation, the South-West is preparing to welcome faster, more regular and more sustainable transport.
