Denges-Morges, Additional track.
The federal decree on the 2025 stage of rail infrastructure upgrades specifically provides for the implementation of measures to enable capacity on the Lausanne–Geneva line to be expanded.
The project “Denges: voie d’attente” is putting this into effect, creating a holding track enabling freight trains to enter and leave Lausanne marshalling yard without disrupting the flow of passenger trains. This upgrade is also part of the Léman 2030 programme, which aims to improve regional, long-distance and freight services between Geneva and Lausanne. The project will affect 37 plots with no impact on the environment. During the studies conducted for the project, SBB and the Canton of Vaud identified the opportunity to optimise it by converting the track into a complete third track from Morges to Denges (Lausanne marshalling yard). This would improve the line’s capacity for regional, long-distance and freight services and remove a bottleneck. The optimisation would essentially involve adding 200 metres of track and completing a new structure. It would only affect two additional plots (making a total of 39 plots), also with no impact on the environment.
