They do the same in jiu hu. Ktm trains have cracked windows. For some weird reason, kampung boys like to throw stones at passing trains. I would like to know if high speed rail is opersting, if that same behaviour persist, what the conclusion will be like if the front windshield is smashed.
But in this video, it looks to me like the guy wants the driver to open the door. Missing a train is no laughing matter.
