Rail systems throughout the world use GPS to track the movement of locomotives, rail cars, maintenance vehicles, and wayside equipment in real-time. Tracking the location, which track is being utilized, allows rail management to switch trains to different tracks to avoid collisions. Once a piece of rolling stock has completed its route, the data is retained for historical reporting as well.  As a result, these railway systems experience fewer accidents, delays, and setbacks, plus increased track capacity, and greater cost-effectiveness.
