The new Beijing-Zhangjiakou (Kalgan) Intercity Railway, a new line and improvement of the existing Beijing-Zhangjiakou Railway, will see the addition of Qinghe Railway Station as a second Beijing terminus, in addition to Beijing North (Beijingbei). The new railway will see a suburban Beijing terminus at Qinghe, which is approximately 15 km (9 ½ miles) northwest of the Beijing North terminus, and presently around 16 minutes away by train.
Qinghe is rather far out (although it does serve a nearby tech hub), and it does not presently have a Beijing Subway connection. However, there are ideas of building one — which could form part of an eventual Subway Line 9 connection. The station is likely to see a major expansion to accommodate longer (16-car) trains, since only a few services into Beijing North will be long, 16-car ones (most will be 8-car trains).
Most of the new HSR line will be designed for speeds up to 350 km/h (217 mph), although the tunnel by Badaling, as well as a “home stretch” from Xiahuanyuan North (Xiahuayuanbei) to Zhangjiakou / Kalgan South (Zhangjiakounan) will see slower speeds at 250 km/h (157 mph). The part from Qinghe to Changping will be good for speeds up to 200 km/h (125 mph), with the city link from Qinghe to Beijing North slower still (at 120 km/h or 75 mph). The new line will skip Qinghuayuan Railway Station, which is only 4 km (2 ½ miles) away from the Beijing North terminus.
This HSR line is being built in all cases, regardless of Beijing winning the 2022 Winter Olympics bid or not. There will also be a branch to Yanqing. In total, the almost 174 km (108 ¾ mile) long line will serve 8 stations, with a future Donghuayuan North (Donghuayuanbei) station reserved for future development.
