At 8:00 am on August 13, 2024, with the smooth departure of the 55880 inspection train from Chengdu East Station, the Zhenjiangguan Huangshengguan section of the Chengdu Qinghai Xining Railway in Sichuan Province successfully completed all tasks of joint debugging and testing, officially entering a new stage of operational testing.

The Sichuan Qinghai Railway starts from Chengdu East Station, passes through Chengdu City and Aba Tibetan and Qiang Autonomous Prefecture in Sichuan Province, Gannan Tibetan Autonomous Prefecture in Gansu Province, Huangnan Tibetan Autonomous Prefecture, Haidong City, and Xining City in Qinghai Province, and connects to Xining Station. The total length of the main line is about 836 kilometers, with a designed speed of 200 kilometers per hour, and it is a national first-class double track railway. The total length of the section from Zhenjiang Pass to Huangshengguan in this operation test is about 70 kilometers, with a designed speed of 200 kilometers per hour. There are four stations including Zhenjiang Pass, Songpan, Huanglong Jiuzhai, and Huangshengguan, among which Zhenjiang Pass is an existing station and the rest are newly built stations.

The Zhenjiangguan to Huangshengguan section of the Chuanqing Railway, as a key link connecting Lanzhou, Xining, and Guangzhou in China's magnificent "Eight Verticals and Eight Horizontals" high-speed railway network, will greatly shorten the time and space distance between Chengdu and Huanglong Jiuzhai Station after its official operation, realizing convenient services for direct high-speed trains. At that time, tourists can easily take the bullet train to Huanglong Jiuzhaigou Station, and then simply transfer to a bus to quickly arrive at Huanglong, Jiuzhaigou Valley Scenic and Historic Interest Area and other scenic spots to enjoy a travel feast. In addition, the opening and operation of this railway section will also become a strong driving force for the economic and social development of the areas along the line, accelerating the flow of resources and promoting industrial upgrading.
