The region between Lausanne and Renens is the densest in Western Switzerland. A variety of work is in progress in order to improve the capacity and frequency of the services we offer you.

At present, the Lausanne–Renens section has three tracks and is a real bottleneck. This is why we are working to improve the infrastructure by adding a fourth track, which will accommodate:

An increased volume.

of long-distance trains between Lausanne and Geneva

Trains every 15 minutes.

on the RER Vaud (Cully–Cossonay).

• We are creating a fourth track between Lausanne and Renens;
• We are also connecting it to Lausanne and Renens stations;
• We are coordinating this work with other SBB projects: renewal of interlocking systems, flyover (railway bridge between Prilly-Malley and Renens), extension of the platforms at Lausanne, terminus conformity and improved access to trains at Renens station;
• Finally, we are renewing all the existing track installations between Renens and Lausanne

The estimated cost is CHF 260 million (±20%).
