Accidents, NOT suicides
This is what fatalities occur in the film, for those of you who have not seen it:
FATALITY 1:
There is a black youth on the platform holding his vicious dog on a lead, and the dog yanks him onto the track as it lunges for rats on the rails. Then as his friends try to help him up, Crook's train runs him over. It's not known what happened to the dog.
FATALITY 2:
A businessman is accosted by youths on his way to the platform, then has a heart attack near the edge, and he falls onto the track, possibly already dead. Again, Crook's train runs him over.
Now, this is where it gets depressing and serious, because not all drivers are aware they may simply be accidents or genuine suicide attempts. But these WERE accidents.
Unfortunately, these are the only ones. Everything else is deliberate.
