Have you ever experienced a quiet carriage (车厢) while traveling by high-speed railway in China? According to China State Railway Group, some high-speed rail lines, including the Beijing-Shanghai, Beijing-Guangzhou, and Chengdu-Chongqing routes, have introduced quiet carriage services. The service has received overwhelming response among travelers and become a trending topic on Weibo. 

Passengers are able to choose quiet carriages when purchasing train tickets on 12306.cn —the official train ticket booking system website. On the 12306 App, trains with quiet carriages will have a “quiet (静)” character as a prompt (提示). If you want to buy a second-class ticket with quiet carriages, you can select the option “Please prioritize allocating a quiet carriage seat for me.”

Upon purchasing, a friendly reminder will pop up. Passengers in the quiet carriage are expected to cooperate by following these agreements: maintain silence, wear headphones or turn off external sound functions when using electronic devices, set phones to silent or vibrate mode, step out of the quiet carriage when making or receiving calls or conversing, and ensure children are well-behaved to avoid disturbing others. 

The doors and walls of the quiet carriage noticeably feature clear signs, gently reminding everyone to maintain silence. To further create a quiet atmosphere, the voice announcements in the quiet carriage are lowered to 30% to 40% of the standard volume. Furthermore, the conductor is equipped with the arrival information of each passenger, enabling them to offer personalized one-on-one arrival reminders. The conductor also provides gentle reminders to the passengers, reminding them to maintain a quiet environment within the quiet carriage. When the meal service staff enters the quiet carriage, they will stop introducing products. If passengers require catering (饮食服务) services, they can conveniently scan (扫描) the QR code on the armrest of their seat, follow the displayed instructions to place an order, and the staff will quickly deliver the items to their seat. The train also provides passengers with items such as eye masks, earphones, and snore (打鼾) stoppers.
