Increase Your Chances of Seating in “Non-Reserved Seats” Cars During peak season, it can be really hard to get a reserved seat for Taiwan High Speed Rail (HSR) tickets. Either you book months in advance, or you can get one of those “non-reserved seats” tickets. Each HSR train usually has 3 non-reserved seat cars (usually cars 10, 11, and 12). However, the issue with non-reserved seats is that they don’t guarantee you a seat, and you might have to stand for hours on the train 😿.
