Switzerland is such a small country that there isn't enough time to get a decent sleep before you get to one of its borders, no mater which route you pick (even a "long" one like Geneva to St. Gallen), and even if you cold find a foreign train with sleeping cars. When I was young the only overnight trains I recall were the ones running from Germany through Switzerland to Italy. The big disadvantage in my mind is that when you are on a night train you are sliding by all kinds of interesting scenery and missing it all. I should add that not all scenery is created equal.
One of my current projects is to go across Russia on the Trans-Siberian. I'm sure I'll be missing some interesting scenery but if I got off the train to sleep at a stop each night, that would probably double the total time required to complete the trip, from one week to two. But it might be worth it for some parts of the run.
I wonder if the Copenhagen - Oslo, Oslo - Stockholm, and Stockholm - Copenhagen overnight trains are still running.
