During my time in Switzerland, I found it very easy to travel using any mode of transportation available. The facilities are complete and clean, with both seating and a clean, odor-free restroom. Security is excellent, and the staff are responsive and friendly. Please note, we must follow the rules of train transportation. There are first and second class. If you book second class but sit in first class, you will be approached by ticket checkers and fined. Food and drinks are permitted inside, as long as cleanliness is maintained and the charging facilities are complete and functioning properly. In short, the quality of service is commensurate with the premium price. Thank you, and I am also satisfied with purchasing here because the payment methods are complete and you can immediately issue a ticket that can be used immediately upon booking.
