Trip got started off poorly due to translation issues. This isn’t the same train, but it still demonstrates the point. The sign says “may” exit the train. I had a choice. So I stayed because I didn’t want to haul my luggage around any more than I had to. Well, “may” should have read “must” because the train went back the direction it came from. Got that straightened out and then went to take the MagLev train, but apparently I was too early to ride it, so it was back to the subway. Wasted just enough time that my flight was pretty much beginning boarding when I got through security…
