Obviously...but I'm not seeing where you get the figure 60 kph. But even if the train slowed down to 60 kph (again, not immediately seeing the source for that) for the exchange of the "shuttles" you have to assume the train speeds back up to something considerably faster than that right away. (I just used the 150 mph as a random figure that seemed appropriate for what seems to be a high-speed train.) To have the train run at 60 kph for an extended period of time would defeat the purpose of having it NOT stop. So, my question is still not answered.
