What does Gao Tiejing mean?

Gao Tiejing means that there is no noise in the carriage to disturb the passengers.

12306 Static means that the train has a "static train", which is a quiet and comfortable train built by China Railway. Different from ordinary high-speed rail, there is no sound in the whole process, no loud voice broadcast, only the display screen shows the site information. Conversation is forbidden in the carriage, and electronic equipment needs to be muted or turned off. You need to leave the car to answer the phone.

In order to provide a comfortable and quiet ride environment for passengers who like quiet, China Railway Department has set up quiet carriages on some high-speed trains. Passengers can choose a quiet car when purchasing tickets, and the word "quiet" will be displayed on the ticket, indicating that you bought the ticket from a quiet car.

Advantages and disadvantages of silent cars.

The sound insulation effect of quiet car is better than that of ordinary carriages, which can not only isolate the noise between carriages, but also isolate the noise generated by rail friction during carriage operation, so that passengers can feel more at ease when working and resting in carriages.

Similarly, in a quiet car, it is required to keep quiet all the time, so even the arrival information of the train is played through the electronic display screen. If passengers don't pay enough attention to check the arrival information, they will miss the station, thus wasting time and causing some trouble.
