Nitpick, on such a long train ride, you will usually have multiple ticket checks because the crew will have a shift change inbetween. Train staff, unlike airplane staff, usually return home after every shift. After having been on the train for 3 hours or so, they will get off, have their break, then go back on the same line to their home base.
