Role and function:

1. To protect passengers’ eyes from light stimulation. When trains are running at night, once the train enters the station, the lights on the platform will be very bright, which may cause passengers to be suddenly attracted by the light and wake up. To prevent this from happening, the flight attendants will ask all passengers to close their awnings to keep the cabin dark. This can better protect passengers' eyes and prevent their sleep from being disturbed.

2. Pulling up the awning can protect the privacy of passengers. The train will pass through various platforms during its journey, and there are often people waiting on the platforms. If passengers do not close the awning when sleeping, people on the platform may be able to see the sleeping position or some private movements of the passengers, which will leak the privacy of the passengers. In order to provide each passenger with a relatively independent space, the flight attendant asked to close the awning to protect the privacy of the passengers.

Pulling up the awning also prevents theft in the car. The train carriage is small and there are many passengers, so it is easy for your belongings to fall out or be stolen. Especially at night, the field of vision is poor and it is easy to be paralyzed. If a vehicle passes by a brightly lit area, someone may become greedy and steal the property if they see it. Therefore, flight attendants will remind passengers to keep their belongings and close their awnings before entering the station.

4. Pulling up the awning can also protect the mental health of passengers. During night train travel, some sections may pass through desolate areas. Facing a dark environment, passengers can easily develop fears or hallucinations. When there are many people in the carriage, passengers will be more likely to feel oppressed. In order to prevent passengers from having adverse psychological reactions, the flight attendant asked the awnings to be closed to try to maintain a quiet and comfortable environment in the carriage.
