The Shijiazhuang–Taiyuan high-speed railway, or the Shitai passenger railway (simplified Chinese: 石太客运专线; traditional Chinese: 石太客運專線; pinyin: Shí-Tài Kèyùn Zhuān Xiàn) is a 190-kilometre long (120 mi) high-speed railway operated by China Railway High-speed, running from Shijiazhuang to Taiyuan, respectively the provincial capitals of Hebei and Shanxi, at 250 kilometres per hour (160 mph). The railway opened on April 1, 2009.[1] It now forms part of the Qingdao–Yinchuan corridor.
The railway crosses the Taihang mountain range through the Taihang Tunnel, which, at almost 28 kilometres (17 mi) long, is (as of 2010[update]) the longest railway tunnel in China.
The Shijiazhuang–Taiyuan high-speed railway is used by G- and D-series high-speed trains. Initially, they mostly ran between Taiyuan and Shijiazhuang. With the opening of the Beijing–Guangzhou high-speed railway, which runs through Shijiazhuang, in December 2012, almost all of these trains have been extended beyond Shijiazhuang; most of them now continue north to Beijing, while some go south, to Wuhan, Guangzhou, and other points along the line.[7]
