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 begin.
