Changsha-Zhuzhou-Xiangtan Intercity Railway, China
The Changsha-Zhuzhou-Xiangtan intercity railway is a two-lane high-speed rail line under construction in Hunan Province in central China. The 95.5km-long railway line will link the provincial capital Changsha with Zhuzhou and Xiangtan.
The major section of the line, featuring 17 stations, was officially opened for passengers in December 2016. The initial operating speed on the line is 160km/h, which will be eventually increased to 200km/h.
With an estimated cost of CNY24.05bn ($3.38bn), the high-speed line covers a Y-shaped route from Changsha to the two terminal points, which is expected to reduce the travelling time between Changsha-Zhuzhou-Xiangtan by 30 minutes. The railway line is operated by Guangzhou Railway (Group) Corporation.
The line will have a total of 24 stations. Construction of 16 stations south of Changsha along with Changsha station was completed and the stations were opened to traffic by December 2016, while seven stations to the west of Changsha are currently under construction with completion scheduled for 2017.
