The monitoring committee for the LNSO (New Line of the South-West) in Haute-Garonne provided an update on project advancements, covering railway works, environmental measures, and long-term project monitoring.

During its meeting on September 28, the LNSO monitoring committee in Haute-Garonne highlighted the project's latest developments. Discussions focused on crucial topics such as the Railway Developments North of Toulouse (AFNT), preliminary operations on the new line's right-of-way, and monitoring the project's long-term effects on the territory.
The AFNT are progressing significantly, with 40% of the program already completed. Since 2024, nine exceptional operations have facilitated the construction of major structures, adhering to the established schedule. Work is now continuing on tracks, platforms, overhead lines, civil engineering structures, and railway beds.
Deforestation operations, which began in September, were also a key point of discussion. These interventions are necessary prior to archaeological diagnostics and geotechnical surveys on the affected areas. The committee discussed the planned support measures, particularly compensation schemes for natural and forest environments, as well as agricultural activities.
Finally, the LNSO Observatory, a scientific initiative designed to track the project's long-term effects and its integration into the territories, was introduced. Its work will encompass the impacts of construction sites, mobility, economic dynamics, biodiversity, landscapes, agriculture, and environmental monitoring.
These monitoring committees, established by prefects in each of the five concerned departments, bring together elected officials, state services, and project owners. They serve as a vital dialogue framework for sharing project progress and addressing local concerns.
