Hi John -
Lucas mentioned the luggage services.
I use them routinely, as long as I have two or three days in one location.
Often I use the "Basic" service.
Once in a while I use the "Express" services. Too expensive for me most of the time, but once in a while it is worth it for me.
The SBB website gives a few more details, including price, the stations where "Basic" works, and the limited number of stations where "Express" service is available.
For any service to work, you have to deal with manned stations.
Many small stations in the countryside are no longer staffed...just a ticket machine.
One way to deal with that is to set up a base or two and make day trips.
The country is quite small....roughly the size of New Hampshire and Vermont combined. Pennsylvania has about 3 times the area. So, a train trip to most places from a central location isa good day trip. Some of the most scenic routes are a bit remote, but time spent with the timetable:
and this map:
will help you figure it out.
Make sure to read the introductory page for the timetable at that link.
On the map, zoom in far enough and you can see the train lines.
I have reached the stage in life where I don't pinch pennies on my trips to Switzerland, except that I do try to stay at less expensive country inns with good kitchens and wine cellars. I have developed a travelpattern that works for me.
I don't spend a lot of time in the famous places unless I am going in June or September. Sometimes May, but then I don't go up in the Alps. Too early.
So, my pattern is to fly into Zürich from the USA, spend a day or two in Zürich on day trips by train while recovering from jet-lag, rent a car ( not at the airport because of the surcharge) and drive to a countryside destination with low tourist density. From there, I may take a train to meet a friend from Geneva, or to Bern, or take the car to a trail head and hike to the other end, then catch a bus or train back to my car. The car may sit for a day, or may be used for some local sightseeing to places for good photography. At the end, I return to Zürich, I dump my luggage at the hotel ( I have memorized the complex car route needed to get me there through the maze of one way streets in Zürich) and turn in the rental car a few days before my departure. On those days, I frequently visit a friend near Luzern. If we meet in Luzern , it is less than one hour by train, and the ride has nice scenery.
Just for examples, I stay in Sumiswald in the Emmental, and in Ligerz on Lake Biel ( der Bielersee) on the French-German language border. I've attached some images.
The Bären in Sumiswald is a famous old well run inn, with a good kitchen and a astorng wine list.
The website is in German, but you can look at the pictures. The staff speaks English.
Gasthof Kreuz in Ligerz is a small inn, with very nice rooms and an elevator. The kitchen has a limited menu, emphasizing fresh fish from the lake, and Herr Mettler is an excellent cook. Several of the wines come from a family vineyard nearby.
Their website is down at the moment. The Mettlers worke in Vermont or a few years.
I did not attach images from the high Alps, but there are plenty of those around.
I carry a half-fare card, and do not find it inconvenient to buy tickets for each trip. The machines are fast and easy (unless you get into complicated special tickets in cities and surrounding zones).
