Hi pstaff,
You can travel from any station to any station, whatever you prefer. There's not really a booking process. You simply go to the rail station, buy a ticket from the staffed counter or a machine, board the train, and find a seat. There's nothing more to it. And you don't even need tickets if you have a Swiss Travel Pass. You can just board any train you like. Only trains requiring reservations are slightly more complicated because you need to arrange for the reservation in advance, and seats can be booked out if you wait too long.
