The Chifeng–Kazuo high-speed railway (also referred to in Chinese as the Chika high-speed railway) is a double-track electrified railway connecting Chifeng, Inner Mongolia and Kazuo Station of the Beijing–Shenyang high-speed railway. The line passes through Harqin Zuoyi Mongol Autonomous County and Jianping County, both administered by Chaoyang City. It then passes into areas administered by Chifeng: Ningcheng County and Pingzhuang town of Yuanbaoshan District to the existing Chifeng station (formerly known as Chifeng West station) on the Beijing–Tongliao railway. The main line has a total length of 157 kilometres and the target design speed is 250 kilometres per hour. ^[1] A connecting curve to the Beijing–Shenyang high-speed railway on the west side of Kazuo station to/from Beijing is proposed. The railway was built in the second half of 2016 ^[2] and joint commissioning and testing began on April 1, 2020. It was officially opened for operation on June 30, 2020. ^{[3] [4]}
