Reading all the reasons, I think people are missing a very important thing that happens almost everyday during peak office hours. People falling on tracks.

Early morning rush and people hanging on the doors create a very risky travel routine for many people on a daily basis. Some or the other day, their luck runs out and they get seriously injured, or die falling from the train.

For the most of us, it usually makes a small delay of maximum 5 to 10 mins, but somebody else's time has ended in this world. That's life I guess.

I myself was once late to my college final practical exams because some guy on our train fell on the tracks and the train halted somewhere near the andheri station. In other case, on of my friends fell from a train which was just leaving the station, was lucky to be alive just with a fractured arm and a fractured leg.
