Is there another video of talking in the high-speed rail cab?

You can't. Shooting and recording are prohibited in the cab of high-speed trains, in order to ensure the safety of trains and prevent passengers' behavior from interfering with drivers' work. Therefore, passengers should not take photos or record in the cab of the high-speed rail. In addition, the communication equipment in the high-speed train driver's cab is specially used for train operation and command, and is not allowed for private communication of passengers. Therefore, there should be no communication activities in the cab of the high-speed rail, including shooting videos, making phone calls and sending text messages. This is to ensure the safe and smooth operation of the train, and also to respect and trust the driver.
