Starting in September, extensive maintenance and modernisation of Switzerland’s SBB network will cause disruptions on a number of key lines in the French-speaking part of Switzerland. Here’s what you should know.
The works will cause interruptions in rail service between Lausanne and Puidoux (Vaud) for two weekends – from September 5th to 8th, and from November 28th to December 1st, the SBB announced.
Long-distance and regional trains will be replaced on this route by buses between Lausanne and Palézieux (IR15) and between Lausanne and Fribourg (IC1).
For long-distance journeys on the east-west axis, passengers are advised to use the Pied du Jura line (via the IC5 connections).
On this section, the work involves the renewal of safety installations and structures between La Conversion (Lutry) and Puidoux.
