I have a newspapers.com subscription. I always see train/vehicle accidents and people walking getting hit by trains back in the day. How on earth does that happen?? Trains go slow. I'd be willing to bet that the majority are suicides.
It is amazing how those big suckers can sneak up on you.
Tow Boats/Barges on the river are the same. I can't count the number of times I have been fishing, particularly at night, and had an oh shite moment, look up and surprise, a million tons of barges 200 yards off and coming fast. I have learned to watch closer but I still keep a big sharp knife handy in case I have to cut the anchor rope and run.
A few years back a member of a fishing board I haunt was run down, a couple hours later they found his boat rolling in front of a tow and it was a week before they found what was left of him. It might have been much longer but a mate of his was supposed to join him, when he got no answer on the phone he called for help knowing something had happened.
