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 will allow Beijing Railway Station to operate as a through station, instead of a terminus, connecting Southern and Western destinations with North East China.^[1] This short line has a length of 9.156 kilometers, including the Beijing Railway Station and Beijing West Railway Station renovated trackage. The line on March 20, 2015 officially opened.^[2]

History

Seen as a restriction for rail services, various proposals have been put forward to connect these two major rail hubs. The current line's planning had already begun early in 1980, planned as a conventional railway. It 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.

December 24, 2005 was proposed again and intended to start construction over a total duration of 2.5 years, in time for the 2008 Beijing Olympic Games.^[1]^[3] However in 2007, problems were encountered with a direct impact on the project schedule, and the project could not be completed and put into use before the Beijing Olympics. Thus the project was delayed.
July 2013, the project successfully completed construction.^[4]
December 19, 2014 the line completed the static inspection and acceptance.
December 30, 2014, test trains began running.^[5]
March 20, 2015, Beijing Underground Cross City Railway officially opened, with the first train being from Shijiazhuang to Chengde (K7742/7743, K7744/7741) train.^[6]
