History

The Airport Express was originally planned to run non-stop between Dongzhimen and the Capital Airport. An intermediate stop at Sanyuanqiao was subsequently added for the convenience of passengers connecting to Line 10.(Chinese

Designers for the new line considered several types of technology for the Airport Express, including: * high-speed maglev, similar to that of the Shanghai Maglev Train * low-speed maglev, similar to that of the Linimo line in Japan * conventional traction motor, electric motor propulsion * linear motor propulsion The linear motor option was ultimately decided upon. Planning accelerated after the city won the bid to host the 2008 Summer Olympics, 2008 Summer Olympic Games, which included a promise to connect the airport to the Olympic village by subway.

2006-08-18 Retrieved [2012-12-29] At the time, Zhang Jianwei, chief country representative for Bombardier, called the short timetable for a project of this type unprecedented. Zhang expressed confidence that Bombardier would meet its responsibilities as its Chinese contractors routinely worked 24 hours a day, something not possible in other countries. He also noted, however, that even if the line were to open on time, the need for haste could compromise the quality of construction. There was also considerable uncertainty over the progress of the project, the identity of contractors and its operational arrangement. Construction was reported to have begun on June 14, 2005, but aspects of the project still awaited the central government's approval. Local media reported in January 2005 that the train supplier had been “basically decided”, but was not officially selected and announced until March 2006. Track-laying began in March 2007 and was completed by November 2007. Testing using empty trains commenced in April 2008 and official operations started on July 19 of that year, in time for the opening of the Summer Olympic Games on August 8, 2008. The line delivered 2.17 million rides in 2008. A western extension to

system, which is capable of driving trains automatically, although staff still monitor the trains from the front (Grade of Automation level 2). At the time of opening, this system made the Airport Express the first rapid transit line with automated operation in China, and the second such rail line of any kind, after the people mover in Terminal 3 at the airport, which was also supplied by Bombardier. Since January 2020, the interiors of the QKZ5 trains were being renovated. The LCD TV display in the passenger compartment has been changed to a 27-inch smart multimedia display that can display flight information and the static paper route map above the door has also been replaced by dynamic LCD screens showing maps and passenger information. In September 2018, an announcement requesting an 8 additional linear motor trainsets was made. CRRC Changchun won the bid in November of the same year. In 2021, the first train was delivered. The new trains have a blue livery was delivered, equipped with wider seats and mobile phone charging sockets.

Others

In the short term, there is little scope to increase the Capital Airport Express's capacity. The 4-car train sets used on the line have significantly lower capacity than those on other Beijing Subway lines, which operate 6-car or 8-car train sets. Also, the Capital Airport Express track design requires trains from Terminal 3 to first travel to Terminal 2 before returning to the city. If trains were able to return directly from Terminal 3 to the city the capacity on the route could be increased.
