It could be real. I think it was a chain reaction. The first one said: "fuck that, I wanna go home", and just quit praying. Next, the other guys next to him did the same. Then, the rest said: "yeaaah, fuck that. I won't sleep on the platform tonight. I am going home". Then everybody's survival mechanism kicked in, and had to flee, before the train was gone!
