1 . Many of you have probably had this experience: You get on a train and are ready to take a nap or read a book, only to find that the passenger in front of you is watching a TV show on his cellphone without headphones. The child next to you won't stop crying. And the old lady behind you talks on her phone during the whole trip.

Wish the train could be less noisy? There might be a solution for you. The Beijing-Shanghai high-speed railway, one of China's busiest high-speed rail lines, will have “quiet” carriages starting from Dec 23, Xinhua reported.

In quiet carriages, onboard videos will be muted and announcements will be made at a lower volume. Doors at the ends of the carriage will be kept closed to reduce noise from other carriages, CGTN noted. Train attendants will be responsible for making sure that passengers remain quiet and follow the rules.

Passengers who are willing to obey the rules can choose the quiet carriages when booking their tickets, according to China's national railway operator.

Some people have pointed out that this kind of quiet environment should be offered in all carriages. They say that having quiet carriages might give people the impression that they don't need to be quiet in non-quiet carriages.

While some Internet users are upholding the new service, it has also sparked discussion about just how quiet travelers should be in quiet carriages. Many people have raised questions such as “What if I snore?” and “Can we talk to our travel companions if we need to?”
