Construction of Lausanne-Renens flyover.
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.
- The flyover is linked to the Lausanne-Renens 4th track project. Its construction is one of the conditions for developing services between Lausanne and Geneva, as well as the services provided by RER Vaud.
