No time is wasted. The bullet train is moving all the time. If there are 30 stations between Beijing and Guangzhou, just stopping and accelerating again at each station will waste both energy and time.

A mere 5 min stop per station (elderly passengers cannot be hurried) will result in a total loss of 5 min x 30 stations or 2.5 hours of train journey time!

The passenger at a station embarked onto to a connector cabin way before the train even arrive at the station. When the train arrives, it will not stop at all. It just slows down to pick up the connector cabin which will move with the train on the roof of the train.

While the train is still traveling away from the station, those passengers will board the train from the connector cabin mounted on the train’s roof. After fully unloading all its passengers, the cabin connector cabin will be moved to the back of the train so that the next batch of outgoing passengers who want to alight at the next station will board the connector cabin at the rear of the train roof.

When the train arrives at the next station, it will simply drop the whole connector cabin at the station itself and leave it behind at the station. The outgoing passengers can take their own time to disembark at the station while the train had already left. At the same time, the train will pick up the incoming embarking passengers on another connector cabin in the front part of the train’s roof. So the train will always drop one connector cabin at the rear of its roof and pick up a new connector cabin in the front part of the train’s roof at each station.
