A passenger rests in the "quiet car" on the G2 bullet train of the Beijing-Shanghai high-speed railway, which links Beijing, capital of China, and east China's Shanghai on Dec. 24, 2020. Some high-speed trains in China have piloted "quiet cars" for passengers who opt for a quiet and undisturbed travel experience. The "quiet car" is often the No. 3 carriage on the train, with onboard videos muted and announcements made at a lower volume. Doors at the ends of the carriage will be closed to reduce noise from the vestibule. The service is now available on some trains of the Beijing-Shanghai high-speed railway and Chengdu-Chongqing high-speed railway, starting from Thursday. (Xinhua/Wang Xiang)
