The line between Basel and Basel St. Johann will be closed every weekend in October 2025 due to infrastructure upgrades. TGV services between Basel SBB and Mulhouse, and TER services between Basel SBB and Saint-Louis, will be cancelled every weekend from Friday 10.45pm to Monday 5am. Travellers between Basel SBB and Saint-Louis can use BVB trams 1 and 3.I planned to travel on Sat 4/10/25. Strasbourg to Basel, using SNCF TER to Basel. There seems to be no Saturday service on that date. My final destination is Zurich/Chur any recommendations and does anyone know what has happening?
