Positive Train Control (PTC) is defined in federal law as a “system designed to prevent train-to-train collisions, overspeed derailments, incursions into established work zone limits, and the movement of a train through a switch left in the wrong position.” Should the engineer somehow miss the signals shown wayside or on the in-cab display, the PTC system would automatically slow/stop the train, or switch it to a side track in an emergency.
