High schoolers on trains

Now I have no idea what it was like when you guys went to high school, but I went to a public and private school in the west. If we behaved this way on trains, we would be monitored. There’s students hitting each other with their lanyards on the platform, there’s a group of girls sitting between the carriages. Boys were wrestling next to the tracks. Is this normal?

For reference I’m on the T8 to MacArthur.
