Southwest China transport hubs linked
Print Edition
AT 8:28am yesterday, a bullet train departed Guiyang, capital of southwest China’s Guizhou Province, for a largely mountainous journey that was to end in Chengdu, capital of Sichuan Province.
With a design speed of 250 kph, the train service marked the launch of the 648km-long Chengdu-Guiyang high-speed rail line, an important part of China’s ambitious plan to build a high-speed railway network across the country.
The rail line links Guiyang and Chengdu, two transport hubs in southwest China, providing vast numbers of passengers in the region with a speedy pathway to eastern and southern coastal regions, said Li Yi, a main designer of the railway with China Railway Eryuan Engineering Group.
“The railway is of key significance for tourism, mineral exploration, poverty alleviation, as well as China’s strategy to develop the western region,” said Li.
Shang Qingli, an art group leader from Dafang County of Guizhou, arrived early at the Guiyang North Train Station for the maiden rail service with 30 members of his group.
“We will vigorously promote Dafang’s tourism when we arrive in Chengdu,” said Shang, adding that the launch of the railway line will help promote local tourism as well as the Yi ethnic culture.
Due to the region’s mountainous terrain, about 85 percent of the 648km-long railway tracks were built on elevated bridges or through tunnels.
“In terms of geological conditions, the Chengdu-Guiyang high-speed rail line is one of the most complicated passenger rail projects in China’s mountainous regions,” said Zheng Tao, a designer with China Railway Eryuan Engineering Group.
Zheng said completion of the rail line attests to China’s advanced know-how in high-speed railway construction, citing engineering feats in the project including ballastless slab track, a long-span steel-concrete basket arch bridge and a steel tube-concrete swivel arch bridge.
The rail line is one of the first railway projects in the country whose construction strictly followed an environmentally-friendly guideline, emphasizing minimal impact on the environment and protection of wild animals and plants along the route.
For instance, it took designers three years to devise the optimal rail route across the Minjiang River in order to minimize the impact on a rare fish nature reserve in the vicinity.
