How is shoving distance measured?

Shoving distance is typically measured in car lengths because this unit of measurement provides a practical reference for railroad operations. Car lengths are directly relevant to the length of the train being moved and allow for a clearer understanding of the safe distances involved when shoving movements are executed. Measuring in car lengths helps crew members to ensure they are keeping a proper distance from obstacles, switches, or other trains, thus promoting safety and effective communication on the radio.

While other units of measurement like feet, yards, or meters could also theoretically be used, they do not convey the same immediate and relevant information about the railroad context as car lengths do. By thinking in terms of car lengths, crew members can visualize the situation better, thus enhancing safety and operational efficiency during movements.
