I never understood how people get hit by trains other than being totally oblivious to the mountain of steel that is bearing down on them.
These are fundamentals that we are taught at an early age, "Don't run in the street". "Look both ways before crossing the road" "Don't play on the railroad tracks" and so on....
Maybe it was one of those sneaky trains that lurks in the back of the closet, waiting to pounce. Seriously, though, for two people to be hit, either it was a murder suicide, or they were monumentally stupid.
