Smart self-driving bullet trains will start to run between Beijing-Shanghai, Beijing-Harbin, Beijing-Guangzhou, Chengdu-Chongqing routes before July 1, further entrenching the advantage of China's high-speed railway in the world, said China State Railway Group Corp on Wednesday.

Smart trains have been running in Beijing-Zhangjiakou high-speed railway line in Beijing since end 2019.

"Self-driving" also includes the supervision of human drivers, which is one of the biggest highlights of the automotive.

According to the pre-planned operation guidance from a ground dispatching center, the train can accurately depart, accelerate, de-celerate, automatically operate between the stations, stop at the arrival point while drivers only need to focus on any emergency response.

In order to ensure the safety of train operation, thousands of intel-ligent sensors are installed in the trains to monitor and control the safety of the train.

The interior and carriage service facilities in the new Fuxing bullet trains are also upgraded.  When entering the tunnel, the train can intelligently control the pressure inside the carriage and adjust the lights and windows colors if needed.

Barrier free toilets, wheelchair spaces, SOS buttons are equipped in the seating area for passengers with disability.
