# Beijing–Zhangjiakou intercity railway

The Beijing–Zhangjiakou intercity railway, also known as the Jingzhang intercity railway, Jingzhang high speed railway, Jingzhang section of Beijing-Baotou PDL, is a driverless high-speed railway between Beijing and Zhangjiakou in Hebei province, China. The line was opened on 30 December 2019, and is the world's first fully driverless high speed railway, shortening the traveling time from Beijing to Zhangjiakou from 3 hours 7 minutes to 47 minutes. It forms part of both the longer Beijing–Lanzhou corridor and the Beijing–Zhangjiakou–Datong–Taiyuan branch of the Beijing–Kunming corridor.
The main line has 10 stations. The Chongli Branch has two more stations, Zhaochuan South (reserved station) and Taizicheng. The Yanqing branch has another station, Yanqing railway station. The main line and the Chongli branch opened on December 30, 2019. The Yanqing branch opened on December 1, 2020.
This route has a length of 173.947 kilometres (108.086 mi) of double tracked high speed rail, with a maximum speed of 350 km/h (217 mph) between Badaling West block post and Donghuayuan North. However, within urban Beijing in the south of Changping station, the maximum speed is restricted to 80, 160 and 200 km/h (50, 99 and 124 mph), respectively. The rest of the line has a maximum speed of 250 km/h (160 mph).
The railway was originally scheduled to start construction in 2009. However, because the Ministry of Railways adjusted the high-speed rail construction program, this was postponed until 2014. This railway connects with the Zhangjiakou–Hohhot high-speed railway and Datong–Zhangjiakou high-speed railway in Zhangjiakou.
