There should be a place where people like him could go, where nobody has to deal with the shitty mess they leave or the horror of running them over. A place where they can go and jump down a 100-foot tube with a heavy steel grate at the bottom that flips over automatically after they hit it and dumps the body into a lake full of hungry alligators or piranhas or something.
They could just build the infrastructure to block access to the tracks until the train is stopped and only allow entry and exit from and to the platform, but no one cares.
