Chinese state railway CR invested a total of €46.9 billion (CNY 371.3 billion) in railway infrastructure in the period from January to July 2023, a 7% increase compared to the same period in 2022. In July 2023, CR opened the Xining – Germu section of the Qinghai – Tibet railway line and the Lanzhou – Xining section of the high-speed rail (HSR) line of the same name, and upgraded several lines, including the Xining – Golmud section of the Qinghai – Tibet line. The modernisation of the remaining part of the Lanzhou – Xining line was completed, increasing capacities and reducing travel time between the cities to 59 minutes. Construction of new lines, such as the Liujiashan tunnel on the Chongqing – Qianjiang line and the Haba-Xueshan tunnel on the Lijiang – Shangri-La line, continues to progress. Track-laying on the Chengdu – Yibin HSR line has also been completed. In addition, operational tests on the Qingbijiang – Zhenjiangguan line and speed tests on the Shanghai – Nanjing – Yanjiang HSR line, with trains running at up to 385 km/h, are underway.
