A brilliant new Chinese train innovation - get on & off the bullet train without the train stopping. VERY COOL CONCEPT !
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!
