en.Wedoany.com Reported - The shield machine "Berthe de Puybusque" for the Line C project of the Toulouse Metro in France completed its first tunneling task at the beginning of this month. With a diameter of 10.11 meters and a cutterhead weighing nearly 150 tons, the machine has finished excavating a 2.54-kilometer section from the future Ponts-Jumeaux station to the La Vache Gare – Le Grand Marché station.

During the excavation process, the shield machine arrived at La Vache station in March 2026 and successfully passed through the station's completed reinforced concrete structure. After completing the first tunneling phase, the cutterhead was transported vertically as a whole unit, with a special convoy moving at a speed of 3 km/h between Ponts-Jumeaux and La Vache Gare – Le Grand Marché under security escort. The transportation of all components of the shield machine is expected to require approximately 15 transport convoys, with the first shipments delivering the front part of the machine, including the cutterhead, shield body, and installation machine. The transportation of the backup system began in July and is divided into two phases due to site constraints: heavy components are moved using flatbed trucks, while lighter parts and fluid pipelines are transported along the metro line.

After reassembly at La Vache Gare – Le Grand Marché, the shield machine will begin a 2.12-kilometer tunneling operation toward the future Raisin station. Line C of the Toulouse Metro spans approximately 27 kilometers in total, with 21 stations connecting Colomiers and Labège. Once operational, it will complement the existing manually driven Metro Lines A and B.
