To run even a, say, “simple” traditional grain train—6,700 feet, 28 million pounds—through the ice fog of a late February night, applying the physics of the horsepower and weight to a landscape you cannot see, but must know—every inch of, every hill and dip, every crossing, every signal mast is something no office worker can imagine. Why are train engineers expected to know every nuance of the route, when it should be trivial to do fine-grained GPS maps of the tracks and provide moving map displays that could show every hill and dip, every crossing, every signal mast. This shouldn't be left up to the memory of the engineers. There's already automation that could enforce speed limits, but for some reason it relies on track-side equipment so isn't universally available: https://www.businessinsider.com/amtrak-derail-washington-positive-train-control-tech-2017-12 https://www.businessinsider.com/amtrak-derail-washington-pos...
