Six next-generation subway cars finished their trial run on a test line this Wednesday in Qingdao, east China’s Shandong province, said CRRC Qingdao Sifang, a Chinese publicly traded rolling stock manufacturer.

The latest subway cars adopted substantial new technologies and materials, representing the future trend of subway development. They are expected to lead the upgrading of subway technologies and make subway trips more enjoyable.

According to Ding Sansan, deputy chief engineer of CRRC Qingdao Sifang, the subway cars are lighter and save energy. They are built with the most advanced composite carbon fiber, and are 13 percent lighter than the previous generation.

Thanks to the newest silicon carbide inverter and permanent-magnet synchronous motor, the subway cars reduce energy consumption by more than 15 percent compared with traditional models.

The windows of the next-gen subway cars have been turned into huge-screen computers that make the glass look like huge iPads. Passengers can surf the internet and watch videos with a simple click.

In addition, the new sound-proof materials applied can reduce the noise inside the cars by over 5 dB, and the new facilities, such as smart air conditioners and smart lighting, will also create a more comfortable ride for passengers.
