We will have Swiss Travel passes and we want to travel by train from St. Moritz to Chur to Zurich to Interlaken Ost, to Lauterbrunnen and then to Wengen later this month. We are not taking the panoramic train from St. Moritz to Chur. We will be talking a standard SBB train. Do we need to have reservations for this train anyway, or will we be OK just showing up at the train station in St. Moritz and hopping aboard?
Thanks for your advice.
