Beijing Underground Cross City Railway is a short high-speed railway connection in the Chinese capital city of Beijing. It connects the important transportation hubs of Beijing Railway Station and Beijing West Railway Station. It has allowed Beijing Railway Station to operate as a through station, instead as a terminus, connecting southern and western destinations with north-east China.^[1] This short line has a length span of 9.156 kilometers. This line has been officially operational since March 20, 2015.^[2]

History

In early 1980 a plan was proposed to connect these two major rail hubs 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 was not started.
