On September 25, 2019, Beijing daxing international airport officially opened to traffic. As one of the most important supporting projects of Beijing's new airport, Beijing daxing international airport line, the lifeblood of the rail transit between the city and daxing international airport, was opened simultaneously.

Beijing new airport line is an important supporting project of daxing international airport. The new airport line train is manufactured by CRRC sifang co., LTD., commonly known as "moby dick". It is a municipal train tailored for Beijing's new airport line by CRRC sifang integrating advanced technologies of high-speed rail, intercity and urban rail vehicles.

In terms of vehicle structure, "moby dick" adopts the same vehicle limit as the national railway, with A body width of 3.3 meters, which is 30 centimeters wider than the 3.0-meter body width of the model A, the widest of the traditional subway trains. The body length of the intermediate car is 22 meters, which is close to that of the type A subway. Compared with the 25 meters of the CRH6 emu, the body length is reduced to reduce the load and axle weight. All the columns are organized in the form of "7+1", with 448 members. In addition to the seven passenger cars, there is a special car for transporting passengers' checked luggage in the city terminal.

Hongyu ji provides low-temperature plasma air purification equipment for the train of new airport line, which can completely solve the air quality problems in the train, remove harmful gases such as TVOC, formaldehyde, benzene, and eliminate microorganisms such as viruses and bacteria. Its excellent daily sterilization and daily odor elimination features create a healthy and fresh air environment for the train.
