<<"Assuming travelling by train, any circumstances that passengers are able to buy tickets from ticket man/lady?">>
For many years that was possible, but, a few years ago they discontinued the practice. So, the signs help you remember.
Tickets are conveniently available from multilingual ticket machines, as well as at ticket counters. However, the Swiss Travel Pass is super-convenient. (Not the Swiss Pass which is for Swiss residents.)
If you don't travel a lot by train, Arno might suggest some other pass.
What is your itinerary?
