Ankang-Chongqing High-speed Railway is an important part of China's "eight vertical and eight horizontal" high-speed railway network from Beijing to Kunming and from Baotou, Yinchuan to Haikou. Starting from Ankang West Railway Station, the line passes through Ankang City of Shaanxi Province, Chengkou County of Chongqing City, Dazhou City and Guang'an City of Sichuan Province, Hechuan District and Beibei District of Chongqing City, and is introduced into Chongqing West Railway Station of Chongqing Hub. There are 11stations in Ankang West, Langao, Chengkou, Fankai, Xuanhan South, Dazhou South, Dazhu, Guang'an East, Hechuan East, Beibei South and Chongqing West, of which Chongqing West is an existing station. Others are new stations.
Kangyu high-speed rail will continue the Xikang high-speed rail, which has already started construction, and will form a major high-speed rail corridor from Xi'an to Chongqing. After the completion and opening of the Western Chongqing high-speed rail, the travel time from Xi'an to Chongqing is expected to be shortened from about 6 hours to about 2.5 hours, which will further improve the railway network structure in the central and Western regions, greatly facilitate the travel of the people along the line, consolidate and expand the achievements of poverty alleviation, comprehensively promote rural revitalization, and help urban and rural areas. It is of great significance to form a new pattern for the development of the western region.
