A locomotive control feature used to govern train speed at a steady crawl, typically between a fraction of a mile per hour and three miles per hour. It automatically adjusts tractive effort and dynamic braking to hold an exact pace regardless of gradient or train weight. Crews rely on it for continuous loading or unloading operations at coal mines, grain elevators, and rotary dumpers.
