pro-tip: loop your legs and arms through the handles or straps of the bags you're traveling with to prevent people from stealing them while you sleep
e.g. put your backpack on your lap against your chest and cross your arms through the straps, stick your leg through the loop of a duffel bag handle, etc
What could be dangerous with sleeping on a train? I always sleep on trains and buses, I even change when I go to sleep, so I'm tired when on the train, so I can fall asleep.

I suppose it's getting robbed? And that you live in a quite different part of the world than me :-/
