For those looking for a quiet travel experience, China State Railway Group has introduced “quiet carriages (车厢)” on some high-speed trains, which include the Beijing-Shanghai, Beijing-Guangzhou, and Chengdu-Chongqing routes. The service is popular among travelers and has become a hot topic on Weibo.

Passengers choosing the “quiet carriages” are expected to follow a set of rules during the trip, including using headphones when listening to music, turning mobile phones to silent or vibrate mode, making or receiving phone calls outside the quiet carriages, and making sure children remain well-behaved.

Moreover, the volume (音量) of announcements in the “quiet carriages” is kept at 30 percent to 40 percent of the normal volume. The meal service staff will also refrain from introducing products and services within the carriages. A range of amenities (便利设施) such as eye masks, and headphones are available on the trains.

Passengers who want to buy tickets for “quiet carriages” should look for train services with the “quiet(静)” character and choose to prioritize quiet carriages when booking their tickets. The tickets are now available on the 12306 App and website, with third-party platforms (平台) not yet supporting these bookings.
