en.Wedoany.com Reported - Construction of Toulouse Metro Line C continues to advance. As of June 26, 2026, 76% of the tunnel (approximately 21.8 kilometers) along the 28.6-kilometer line has been excavated. This new line, planned to enter service by the end of 2028, is 80% underground, with over three-quarters of the tunnel already built.

Four tunnel boring machines are currently operating beneath Toulouse. These machines are named after prominent women from southwestern France, including: Lise Enjalbert (used by the Eiffage Génie Civil – NGE – BTP consortium), Jeanne Marvig (same consortium), Berthe de Puybusque (same consortium), Marie-Thérèse de Villeneuve-Arifat (used by the Demathieu Bard Construction and Implenia consortium), and Marguerite de Catellan (used by Bouygues Travaux Publics in partnership with Soletanche Bachy France and Bessac). The first three machines come from the Grand Paris Express Line 16 and were refurbished in Thieux, in the Paris region. The machines are lowered into the ground via baskets or cranes from metro stations and then reassembled, a process that can take weeks or even months.

Construction sites for all 27 stations are ready, and subsequent tunneling will connect each station. Excavation is not linear but proceeds simultaneously across multiple sections, each managed by different consortia to accelerate progress. The tunneling speed is influenced by factors such as soil composition, equipment maintenance, and the discovery of sand pockets (which require concrete injection) along the route. All excavation work is expected to be completed by early 2027. Tisseo has created a webpage that updates project progress every ten minutes.
