Welcome Andrei!
The Landwasser viaduct is not close to Zurich nor Interlaken. If you 're willing to spend one night in or near St. Moritz, this is what you could do: from Interlaken, travel to Brig, follow the Glacier Express route to St. Moritz, passing the viaduct. The official Glacier Express does not operate in November, but there are regular trains too. The next day, you could pass the viaduct again on your way to Chur. Change trains for Zurich there.
Make sure to leave Interlaken very early so you won't pass the viaduct when it's dark.
You best pick a pass when you have decided on your itinerary. If you plan to travel a lot, an 8-day Swiss Travel Pass might work (you won't need it to explore Zurich).
Does this make sense?
