New high-speed lines are under construction between Chongqing and Chengdu, as well as Chongqing and Xi’an. China continues to move towards the completion of a 75,000 km high-speed network by 2035. It is reported by Railway Supply magazine with reference to IRJ.


The 292 km long Chongqing-Chengdu high-speed line will have eight stations. It will be built for a design speed of 400 km/h, allowing trains to travel at speeds of up to 350 km/h, with travel times of less than an hour.

The number of freight trains from China to Europe exceeded 10 thousand

The line will be the fourth railway between the two cities and, when completed in 2027, will be “the fastest and most modern high-speed railway in the country,” according to local media reports. The line will connect with several high-speed lines, including the Xi’an-Chengdu and Zhengzhou-Chongqing lines, improving the national rail network in the southwest. China Railway is responsible for overseeing the project.

Work also began on the 478 km Chongqing-Ankang section of the 739 km Chongqing-Xi’an high-speed line.
A speed of 350 km/h will reduce travel time between two cities in western China to less than three hours. The work is expected to be completed in 2028.
Construction of the Ankang-Xi’an section began last year and is expected to take five years.
