AMAZING! The train that never stops at a station is a brilliant new Chinese train concept, you board and leave the bullet train without its stopping.
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 minute 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! With this new concept, no time is wasted.
How it works (view the movie - in Mandarin though!):
FOR THOSE BOARDING THE TRAIN: The passengers at a station embark onto to a connector cabin way before the train even arrives 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 moving 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 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.
FOR THOSE ARRIVING: After fully unloading all its passengers, the cabin connector cabin will move 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. The outgoing passengers can take their own time to disembark since the train has 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 off one connector cabin at the rear and pick up a new connector cabin in the front at each station.
