trains are predestined to be driven by computers, they basically are already. switches are generally controlled remotely, not by the driver, except sometimes on trams. on high speed lines, signals are being transmitted into the cockpit instead of standing beside the track. pretty much all a train driver has to do nowadays is operate the throttle/brakes and sometimes the doors correctly, and there are systems in place that prevent them from fucking that up. compare that with the huge machine learning with captchas clusterfuck that are computer-driven road vehicles
