That's absolutely a problem if a train designed to have a driver doesn't have one (which is what happened here). If trains were designed to not need drivers, this wouldn't have happened, because (a) enough mechanical brakes would have been applied automatically, (b) the engine fire would have been detected and reported automatically, and (c) if the brakes failed there would have been an immediate alarm when the train started moving.
