Exceptional operations, a key step for the New South-West Line (LNSO), will take place simultaneously on the development sites of the Railway Developments South of Bordeaux (AFSB) and North of Toulouse (AFNT) between November 21 and 27, 2026. These major interventions will require temporary rail traffic interruptions and reinforced construction site activity.
Teams will work on tracks, overhead lines, signaling, and civil engineering. South of Bordeaux, work will focus on these same areas. North of Toulouse, interventions will notably allow the opening of railway developments and platforms at Castelnau-d'Estrétefonds station, as well as the underpass and central platform at the Route de Launaguet (Toulouse – La Vache) halt.
Train circulation will be interrupted between Bordeaux and Langon from Saturday, November 21, at 2:45 AM to Thursday, November 26, at 12:45 PM. Between Montauban and Toulouse, the interruption will occur from Saturday, November 21, at 0:10 AM to Friday, November 27, at 5:40 AM. Circulation will be maintained between Langon and Montauban.
These long-planned interruptions are anticipated in the transport plans. Travelers are advised to check schedules and traffic conditions on their carrier's usual channels, such as SNCF Connect.
Increased construction site activity may lead to noise disturbances in certain areas. Two mediators, Charles Aboud (AFSB) and Pierre Potin (AFNT), remain available to residents and elected officials.
A final exceptional operation is scheduled for December 5 and 6, 2026, on the AFSB and AFNT.
