For those looking for an undisturbed travel experience, China has introduced "quiet carriages" on some of its high-speed trains.

The silent car features muted videos and announcements made at a low volume. Doors at both ends of the carriage are closed to reduce noise from the vestibule.

The service, introduced on Thursday, is now available on some trains of the Beijing-Shanghai high-speed railway and Chengdu-Chongqing high-speed railway.

Passengers must keep their voice low and wear headphones or turn off speakers when using electronic devices. They should also leave their seats to make or answer calls, and their phones should be muted or turned to vibrate mode during the trip.

"I make at least one round trip a week between Chengdu and Chongqing for work. I sometimes need to focus on my work or get some rest during the hour-long trip. The 'quiet car' is a good choice for me," said Li Like, a 34-year-old Chengdu resident.

"I found the option for a 'quiet car' when I booked the tickets, and I wanted to give it a shot," said Mou Xiaojiang, who took the G8609 train from Chengdu to Chongqing. "When I entered the carriage, signs reminding passengers to keep quiet were seen everywhere, and it was indeed much quieter than other carriages."

The China Railway Shanghai Group Co., Ltd said that it had conducted pre-job training for crew members so as to better serve passengers.

"Many passengers are taking the Beijing-Shanghai high-speed trains for business trips, and they don't want to be disturbed. So we hope that everyone on board will follow the rules and jointly improve the travel experience," said Cai Jingfei, conductor of the G2 Beijing-Shanghai high-speed train.

"The quiet carriage service gives passengers more value-added choices. It will help passengers observe public order, respect the rights of others, and create a more civilized traveling environment," said Ma Liang, professor at the School of Public Administration and Policy at Renmin University of China.
