Years ago, I was on a train (Fast freight- track speed was 60 MPH ) and when we rounded a bend ( were were going 42 MPH ), we happened upon some tresspasers, they couldn't get out of the way fast enough, ... very messy ... and the bullcrap that comes afterward for the crew is ... well wouldn't wish that on anyone !!!!, had someone ( R.R. Official, who pulled me to the side, off record ) tell me afterward " The world is full of stupid people, who don't know their stupid, and you can't fix stupid !, let alone bring back the dead " Flame me if you want, but a roller bearing car is very quiet, and trains just don't stop like cars, and when a train is approaching. it's rate of speed is very decieving, it will be on you faster that you think !!!!
