From June 25, the number of paired railway trains going through Hangzhou will reach 492.5. The number of paired high-speed railway trains linking Hangzhou and Beijing will increase to 21.

Fuxing high-speed trains, China's top bullet train design, will be deployed to link Hangzhou and Beijing. Fuxing trains feature decorative designs incorporating traditional Chinese cultural elements. Patterns of Chinese dragons and phoenixes will be painted on the outer surface of the train.

The Fuxing trains include silent carriages, in which passengers are required to be quiet and to make no noise. The trains also appoint barrier-free carriages to make it more convenient for differently-abled people.

The trains' air conditioning units adopt converter technologies to make temperature regulation more precise and to generate less noise. The technologies will also help lower energy consumption by 10 percent.

According to officials with the national railway authorities, these 17 high-speed railway trains are all covered with 5G Wi-Fi signals. Passengers will be able to access higher-quality mobile network services.
