The 41.4km New Airport Line is, running from an interchange with metro lines 10 and 19 at Caoqiao with Beijing Daxing International Airport North Terminal, serving just one intermediate station at Cigezhuang, which will eventually become an interchange with Line S6. Both Caoqiao and Cigezhuang will have check-in facilities for passengers’ baggage.

The Yuan 41bn ($US 6.1bn) New Airport Line will be China’s first 160km/h urban rail line, offering a journey time of just 19 minutes between Caoqiao and Daxing North Terminal.

CRRC Qindao Sifang is supplying a fleet of trains based on its CRH6 main line EMU and equipped for Automatic Train Operation (ATO).

According to the manufacturer, each eight-car type D train can accommodate 1538 passengers (at 9p/m2). The trains feature 3.3m-wide aluminium-alloy bodyshells, 2+1 seating in business class, a baggage car for checked-in luggage, at-seat USB chargers, and LED lighting, which adjusts automatically depending on the ambient light conditions.

The fleet of 12 trains is also equipped with a fault prediction and health management system to support fleet maintenance.

The line is due to open in September, coinciding with the inauguration of the airport.

In addition to the metro line, the new airport will also be served by the 78.2km Beijing - Bazhou high-speed line.
