A building site has given rise to an impressive structure. The LEB tunnel in the heart of Lausanne was opened on 14 May 2022. Comparison of the pictures from June and November 2021 and March 2022 give an idea of the many different tasks cablex assumed in this project as well as showing the tunnel construction's rapid progress.
LEB stands for the rail route Lausanne-Echallens-Bercher and the tunnel for a major project that makes the infrastructure in the very busy traffic of the city centre smoother and safer. As part of the IGCS consortium, cablex was responsible for the overall project management in terms of electrical installations and carried out implementation of the railway engineering work package.

The LEB major project in three construction phases.
The background.
The overloading of the Avenue d'Echallens in Lausanne resulted in repeated accidents. Pedestrians, motorists, cyclists, buses and trains were travelling at the same time and produced a confusing and dangerous overall situation.
To make the traffic infrastructure safer and more convenient, construction of the 1.7 km LEB tunnel began in summer 2017. It has been in two-lane operation in an 8 m wide and 15 to 30 m deep underpass below the Avenue d'Echallens since 14 May 2022.
cablex assumed responsibility for the overall project management in the person of Philippe Wuillemin as well as for the project management of the train technology in the LEB tunnel construction project. cablex can point to many outstanding references in the infrastructure segment with tunnel projects such as the Ceneri base tunnel, Bözberg, CEVA or maintenance work in the Gotthard tunnel. The successful conclusion of the LEB project once again showed that cablex is not only a reliable and expert partner in network construction and service, but also puts in a convincing performance in road and rail transport with professionalism, experience and quality.
