<span class="mw-page-title-main">Lanzhou–Xinjiang high-speed railway</span> Railway line in western Peoples Republic of China

The Lanzhou–Xinjiang high-speed railway, also known as Lanzhou–Xinjiang Passenger Railway or Lanxin Second Railway, is a high-speed railroad in Northwestern China from Lanzhou in Gansu Province to Ürümqi in the Xinjiang Uyghur Autonomous Region. It forms part of what China designates the Eurasia Continental Bridge corridor, a domestic high-speed railway corridor running from the city of Lianyungang in Jiangsu to the Kazakh border. The line is also shared with conventional trains.

China Railway No.2 Group Co., Ltd. and China Railway Erju Engineering Co., Ltd. were two closely connected companies. They are formerly parent-subsidiary via China Railway Erju Co., Ltd. (CREC). The group is a Chinese construction company based in Chengdu.

The Coastal corridor is a high-speed rail corridor running along the eastern coast of China, stretching from Dalian in the north to Fangchenggang in the south and passing through the cities of Shenyang, Qinhuangdao, Tianjin, Dongying, Weifang, Qingdao, Lianyungang, Yancheng, Nantong, Shanghai, Ningbo. Fuzhou, Xiamen, Shenzhen, and Zhanjiang. The Weifang–Qingdao stretch splits into two, one directly connecting Weifang to Qingdao, the other connecting Weifang to Qingdao through Yantai. As apart of China's "Eight Vertical and Eight Horizontal" network, announced in 2016, this corridor is an extension of the Hangzhou–Fuzhou–Shenzhen passenger railway from "Four Vertical and Four Horizontal" network. The line will comprise a mixture of high-speed railway lines, upgraded conventional rail lines and intercity railways.

The Shanghai–Chongqing–Chengdu high-speed railway is a high-speed rail line under construction in China. The Chinese name of the railway line, Huyurong, is a combination of the abbreviations for Shanghai, Chongqing, and Chengdu. It will run in an east-west direction largely parallel to the Yangtze River, connecting the cities of Shanghai, Nanjing, Hefei, Wuhan, Chongqing and Chengdu.

The Yichang–Xingshan high-speed railway, also referred to in Chinese under the acronym Yichang-Zhengwan high-speed railway connection line, is a high-speed railway under construction between Yichang on the Wuhan–Yichang railway and Xingshan on the Zhengzhou–Wanzhou high-speed railway in Hubei province, China. It will form part of the Shanghai–Chongqing–Chengdu high-speed railway. The total length of the line is 109.38 km (67.97 mi), and there are 3 stations on the whole line. It is a line connecting the Wuhan–Yichang railway and the Zhengzhou–Wanzhou high-speed railway. The line will run from Yichang East station via the Changgangling area and Xiabaoping station to Xingshan station. In addition, this line is also planned to be connected with Yichang North railway station and the Wuhan–Yichang high speed railway, also currently under construction. The estimated total investment of the project is 18.15 billion yuan, the construction period is 5.5 years, the design speed is 350 km/h (220 mph), and 94.37% of the main line will run on bridge or through tunnel. It is expected to be officially completed and opened to traffic in 2024. After the completion of the line, combined with the Zhengzhou-Wanzhou HSR to form a new east–west high-speed railway route in the Sichuan-Chongqing area, the Wuhan–Chongqing route will be shortened from the current fastest service of 5 hours and 54 minutes to about 3 hours, and Wuhan–Chengdu services will take only 5 hours. At the same time, journeys between Yichang and Beijing will be shortened from the current 8 hours to about 4.5 hours.
