The Beijing underground cross-city railway is a short high-speed rail connection in Beijing. 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.[1] The railway has a length span of 9.156 km (5.689 mi), and has been officially operational since March 20, 2015.[2] In 2017, the Beijing Development and Reform Commission proposed a commuter rail service utilizing the tunnel to connect Tongzhou and Shijingshan Districts.[3]

History

In the early 1980s a plan was proposed to connect Beijing Railway Station to Beijing West Railway Station via a conventional railway. This was an important part of the overall planning of Beijing West Railway Station's renovation, originally announced as part of the "Eighth Five-Year Plan". However, due to technical difficulties and other factors, this project did not initiate.
