Union Pacific has implemented the positive train control (PTC) on than a quarter of its track segments. These 59 track segments, or subdivisions, are equipped with wayside devices (signals, switches and radios) and have defined GPS coordinates, which identify thousands of precise locations for systemwide PTC coordination. The PTC-ready segments cover a wide swath of UP’s Western Region, from Southern California to Portland; from Portland to Pocatello, Idaho; and from Roseville, California, through Reno to Elko, Nevada.
Additional progress includes 64% of required locomotives equipped with PTC technology, 85% of required radio towers equipped with PTC technology, 12% of the rail’s required route miles in PTC operation.
