Trains on one of China’s major high-speed rail lines will soon speed up as China rolls out its plan to further speed up its already fast rail service.

From June 20, high-speed trains will be able to run at the increased maximum speed of 350 kilometers per hour along the section of high-speed rail linking Beijing and Wuhan, Hubei province, and part of the railway linking Beijing and Wuhan. Guangzhou, Guangdong Province. , according to China State Railway Group, the national railway operator.

It will cut the travel time between Beijing and Wuhan to 3 hours and 48 minutes, half an hour faster than today.

Last week, the test on this section was a success, showing the viability of increasing the maximum speed of the line from the current 310 km/h.

“It’s a complicated project to operate high-speed trains at 350 km/h, considering technology, market, operating cost and environment,” said Ye Yangsheng, chief engineer. of the China State Railway Group.

The Beijing-Guangzhou high-speed railway opened in 2012 and was designed to operate at speeds of 300 km/h to 350 km/h.

“This popular line has handled 1.6 billion trips, accumulating great operational experience in safety,” Ye said.

In order to increase the operating speed, the group upgraded the railway section, including railway tracks, bridges, tunnels, electrical system, communications and disaster inspection system.

The test thoroughly examined the section.

The other section of the line from Wuhan to Guangzhou opened in 2009 and operated at a maximum speed of 350 km/h from 2009 to 2011, but later reduced the maximum speed to 300 km/h.

The section had opened earlier and had more tunnels and bridges, so it is easily affected by the environment.

The railway will also offer more services to improve passengers’ travel experience, such as quiet compartments and flexible ticket pricing.

The revision of the maximum speed will reduce travel time between the capital and many major cities in the south, such as Shijiazhuang in Hebei Province, Zhengzhou in Henan Province, Changsha in Hunan Province and Chengdu in Sichuan.

China has a network of more than 40,000 km of high-speed railways, the first in the world.
