An integrated transportation system of Beijing Daxing International Airport, an international hub, is scheduled to open in 2019. It will allow passengers to jump onto a bullet train to reach other places in China.
According to a news report from the Beijing Times, a high-speed rail line that links Beijing and Hong Kong will go through underground of the airport. Passengers will be able to reach the railway station at the underground floor of the airport.
Nie Yonghua, an official at the Beijing New Airport Construction Office under the Civil Aviation Administration, confirmed the news, saying the high-speed railway and subway stations will form a rapid transit system that facilitate passenger trips.
He said Beijing municipal authorities oversee the railway and subway projects, which will be put into use at the same time as the new airport comes into service.
The express line for the new airport, running 41.4 kilometres, will start trial operations in September 2019.
The new Airport Express will have three stations: Caoqiao, Cigezhuang, and the new Airport North Terminal Station. Caoqiao will offer parts of the functions of the city terminals. Passengers can check in at the station with their luggage to be carried to the airport terminal directly. Caoqiao will be a transfer station between the new airport express line, subway line 10, line 19 (currently under construction) and line 11 (currently in the planning stage).
The Dongzhimen Station, currently the downtown terminus of the Beijing Capital Airport Express, could also offer check-in service when the western extension of the express line is completed around 2020.
To offer luggage check-in, all the new airport express trains will include one extra luggage car in addition to the seven passenger cars.
The report said the ground floor is for international flight arrivals, the second for the domestic flight arrival, and the third and fourth floor are for domestic and international departure respectively. The design is said to be able to ease traffic pressure of the roads that are connected to the terminals.
"The railway will link Beijing and Bazhou, Hebei province, and play a crucial role in coordinated development of the Beijing-Tianjin-Hebei area," said a news report of The Beijing News.
