  • arranging sensors along the railroad lines, such that the sensors provide overlapping fields of view along a majority of a railroad line between two stations, which sensors operate in an optical range, an infrared range, or a radio-wave range;

    observing routes ahead of the automatically controlled, driverless rail vehicles traveling on the railroad lines; and

    automatically evaluating the sensor output signals, the automatic evaluation controlling, at least in part, the automatically controlled, driverless rail vehicles.
