CHINA Railways (CR) invested Yuan 371.3bn ($US 51bn) in rail infrastructure between January and July 2023, up 7% compared with the same period in 2022, as it focuses on implementing its 14th Five-Year Plan.

CR opened the Xining - Germu section of the Qinghai - Tibet Railway and the Lanzhou - Xining section of the Lanzhou - Xining high-speed line in July. The railway also upgraded a number of lines including the Xining - Golmud section of the Qinghai - Tibet Railway.

The upgrade of the remainder of the Lanzhou - Xining line was completed, increasing capacity and allowing services to operate at up 250km/h, reducing travel times between the cities to 59 minutes.

Construction of new lines is continuing, with breakthroughs in the Liujiashan Tunnel on the Chongqing - Qianjiang line and the Haba Xueshan Tunnel on the Lijiang - Shangri-La line. Tracklaying has also been completed on the Chengdu - Yibin high-speed line.

In addition, commissioning is underway on the Qingbijiang - Zhenjiangguan line, while testing on the Shanghai - Nanjing - Yanjiang high-speed line is progressing, with trains operating at up to 385km/h, according to CR.
