Léman 2030: fourth track and flyover at Renens completed

Between Lausanne and Renens (Canton of Vaud), SBB built a fourth track (about 4 km, roughly CHF 130 million) and a 1,175-metre, up to 9-metre-high railway flyover at Renens (roughly CHF 65 million) as part of the Léman 2030 programme. The Swiss Confederation, the cantons of Vaud and Geneva, and SBB officially inaugurated both structures on 29 September 2022; regular operation with a denser timetable (including a quarter-hourly Vaud S-Bahn service Cully–Cossonay) began in December 2022. The goal is to relieve western Switzerland's busiest rail section ahead of a target of up to 800 trains per day by 2030.
