Guess it depends, when I used to travel to the office every few months I was lucky enough that the train would terminate at my destination. So I could sleep in safety. I've certainly observed commuters set alarms on their watches/mobiles based on their expected arrival times. I find that a little rude, but nobody else every seems to comment..
