BLS completes renovation of Weissenstein tunnel and Solothurn–Moutier line

After a little over two years of construction, BLS reports completing the renewal of the Weissenstein tunnel and the whole 22-kilometre Solothurn–Moutier line; about CHF 175 million from the federal Rail Infrastructure Fund was invested, and SBB was due to resume rail service on 6 June 2026. Brittle rock and large volumes of water extended the work by around six months. Seven stations and stops are now step-free; Solothurn West, Lommiswil and Langendorf are to follow in the coming years.
