The Beijing underground cross-city railway is a short railway connection in Beijing. This railway line includes the Qiansanmen Tunnel. The speed limit is 120 km/h.[1] It connects the important transportation hubs Beijing railway station and Beijing West railway station via a tunnel. It also connects lines from southern and western areas with lines from northeast China.[3] The railway has a length span of 9.156 km (5.689 mi), and has been officially operational since March 20, 2015.[4]

It is used by conventional railway lines such as K7752 from Shijiazhuang to Chengde via Beijing West railway station and Beijing railway station. It is also used by the commuter rail service in Beijing, the Sub-Central line of the Beijing Suburban Railway, which started in December 2017.[5][6]
