Injured travelers remain in hospital after China train collision
All the time..........
Think about every time when I took train by myself, every time it was overloaded in the hard seat carriage. The hard seat carriage is the cheapest rank in the train seat system. That you got a ticket to get on the train does not mean you would have a seat to sit down or have a space to stay (stand, lie down under somebody's but, anyway to put your body there). It always 200%, 300%, 400% or even more.
Rich people of course do not understand how hard it is to stay in the hard seat carriages. Rich people also can have special carriage while in the hard seat carriages people are piled up.
