China’s smartest high-speed train makes remarkable performance
By Lu Ya’nan, He Yong and Ji Fang
The world’s first Beidou satellites-navigated bullet train was put
into service on Dec. 30, 2019, connecting Chinese cities of Beijing and
Zhangjiakou.
The autonomous smart bullet train made a remarkable performance in the
first 15 days since the service was launched. Forty-one pairs of passenger
trains have been deployed, carrying 783,300 passengers with a seat occupancy
rate of 95 percent.
Besides, Chongli railway, Datong-Zhangjiakou high-speed railway, and
Zhangjiakou-Hohhot high-speed railway were also put into use simultaneously,
largely reducing the time needed to travel among Beijing, Hebei, Shanxi and
Inner Mongolia.
The shortest operation time between Beijing North Railway Station and
Zhangjiakou is now reduced from 3 hours and 7 minutes to around 1 hour; that
between Hohhot to Beijing's Qinghe station is reduced from 9 hours and 15 minutes
to 2 hours and 9 minutes; that between Datong and Qinghe now stands at 1 hour
and 42 minutes.
Yang Yang, chairwoman of the Athletes’ Commission of Beijing Organising
Committee for the 2022 Olympic and Paralympic Winter Games, boarded
the debuting train of the Beijing-Zhangjiakou high-speed railway on Dec. 30,
2019 for an inspection tour of arenas in Chongli, a district in north China’s
Zhangjiakou where all skiing and biathlon events will be hosted during the 2022
Beijing Winter Olympics.
“The time needed between Beijing and Zhangjiakou competition zones is
now reduced to around an hour, which is a great promotion for both organizing
the Winter Olympics and popularizing the winter games that is practiced by 300
million people,” Yang said, adding that China has fulfilled its promise made
when bidding for the games.
The Beijing-Zhangjiakou high-speed railway not only shortened
distance, but also made a new high of innovation. It is the world’s first
high-speed railway navigated by the Beidou satellites, and the autonomous
trains running along it are the smartest in the world.
The trains are able to start automatically on scheduled time, realize
autonomous operation, and stop and open the doors automatically at each
station, introduced Mo Zhisong, chief engineer of China State Railway Group’s
high-speed train control system project.
According to him, the Fuxing bullet trains are able to control its
error within 10 centimeters braking from 350 kilometers to 0 kilometers per
hour. In addition, the trains can save 15 percent of electricity.
The trains running on the Beijing-Zhangjiakou high-speed railway are
autonomous as they are connected with the Beidou Navigation Satellite System
(BDS). “There are still drivers in the cabin on other tasks, so the passengers
don't have to worry about it,” said Zhang Bo, a researcher from Locomotive
& Car Research Institute, Chinese Academy of Railway Sciences.
Drivers of high-speed trains used to focus on piloting the locomotive,
and now they can shift their attention on emergency and malfunction response. “This
will not only lower the working intensity of the drivers, but also improve the
energy-saving level and comfort of the trains by collecting and calculating
operation data,” Zhang said.
The Beijing-Zhangjiakou high-speed railway has a gradient of over 30 percent. The Fuxing bullet trains, after upgrading, are able to climb the
slopes even when they lose half of traction. The trains can charge their
underbody batteries when running, and once outages happen, these batteries are
able to drive the trains to nearby stations.
With a screen outside each car of the trains where the seat numbers
are shown, passengers will be guided to their seats within the shortest time. Besides,
the lighting in the cars can adjust brightness automatically according to the
sunlight, and the improved sound-proof technology has reduced noise in the cars
by at least 1 DB.
During the past century, Chinese railway has never stopped its steps
of independent innovation. The Beijing-Zhangjiakou high-speed railway is
building a new model for China’s high-speed rail construction.
