Construction between Lausanne and Renens.
The flyover (railway viaduct) will allow trains to pass over other railway tracks without crossing conflicts with other convoys.
- The flyover will mainly be used by trains travelling from Bern towards Lausanne and Geneva.
- It will also double the capacity of trains between Lausanne and Geneva. Thanks to better traffic flow, customers will benefit from a more stable and punctual timetable. Its construction is one of the conditions for developing services between Lausanne and Geneva, as well as the services provided by RER Vaud.
