Hi Sparkyenos
A couple of refinements to Rockoyster’s succinct, accurate and responsive answers to your queries.
In train cars which have reserved seats, there is an indication near the window for those seats if they are reserved. In days past, it was a paper slip inserted in a small clip, with specifics of the reservation written on it. It might be for only one segment of a longer journey, or for a whole journey. These days, newer cars do it electronically, with a small screen near the window, describing a reservation, if any.
So, you can tell if a seat is reserved by looking there.
On certain excursion trains, such as the Glacier Express, seat reservations are necessary. On International trains, such as from The Netherlands through Germany and Switzerland to Italy, reservations are necessary outside Switzerland and often are used in Switzerland, as part of that longer journey.
As Rockoyster noted, the trains you have listed definitely do not require reservations. Some mountain excursion transport at and near St.Moritz has seasonal closures.
The way to think about the mainline Swiss rail system is that it resembles a city bus line.. Have your ticket (or pass) , hop on any train that day (tickets are generally good for all day), and if you miss one, wait for the next one.
Rockoyster likes the smartphone app. I use it while traveling, and it has become indispensable for quick checks of options, timing, connections, etc. while on the road…actually, on the train. It does a lot more including allowing you to buy tickets and have them on the phone to show a conductor.
But, for trip planning, I find the larger screen of a desktop or laptop computer to be more comfortable. I am considerably older than he, and set in my ways. He is much more willing to use newer technology, to good avail, I’m sure.
For example, I like to refer to websites by their actual URL, because they have a name which I can remember. He likes the shorter “short cut” URL’s as he has illustrated.
So, although I would start with the My Swiss Alps link that he provided,
http://www.myswissalps.com/ti metable
because it has useful and necessary tips for getting he most from the timetable (such as the use of the “via” function), once I have internalized that guidance, I tend to seek a URL with a name:
http://www.sbb.ch/en/home.htm l.
No matter how you get to it, it is a very complete compendium of information about the entire train system, not simply a timetable. And, I find that viewing the station map for a large and complex station such as Zürich is best done on the largest screen possible.
Finally, because there are seasonal issue with the travel system and weather, we like to know your exact travel dates. It often allows us to provide a more detailed perspective, or make note of scheduled cableway maintenance during certain times of the year.
When are you traveling?
