Beijing-Guangzhou high-speed train to reach 350 km/h in June


The Beijing-Wuhan section of the high-speed railway connecting the Chinese capital with the southern city of Guangzhou will use trains running at a maximum speed of 350 km/h starting in June, the China Railway has announced.


A test was conducted on the section linking Beijing with the provincial capital of Hubei in central China on Friday.


The test used a Fuxing bullet train and high-speed integrated testing vehicle, with a comprehensive check on up-down track, bridge, telecommunication, signal and overhead line system. It started from Beijing West Railway Station and ran south along the Beijing-Guangzhou High-speed Railway.

During the test, the train's speed reached 385.1 km/h at one point.


The current maximum operation speed along the 2,300-km rail between Beijing and Guangzhou is 310 km/h.


Ye Yangsheng, the chief engineer at China Railway, explained to China Media Group (CMG) some of the safety considerations for trains operating at such speeds.


"The acceleration of high-speed trains requires comprehensive consideration of various factors such as technical conditions, market demand, operation cost and environmental remediation," he said.

"Inside tunnels, the high-speed train is in a semi-closed environment. The increase in air pressure brings additional resistance, which makes the running resistance up by about 30 percent compared with open line conditions," Ye added.


After the success of the test, the Beijing-Wuhan section of the line will operate at 350 km/h starting June 20.


Currently, there are only four high-speed rails in China operating at 350 km/h, mostly in short-distance travel. They are: Beijing-Shanghai high-speed rail, Beijing-Tianjin intercity rail, Chengdu-Chongqing high-speed rail, and certain parts of Beijing-Zhangjiakou high-speed rail. The Beijing-Guangzhou rail is also the longest in terms of travel distance.
