What is the definition of restricted speed for trains?

The definition of restricted speed for trains is correctly identified as not exceeding 15 mph. This speed limit is crucial for ensuring safe operations in potentially hazardous environments where conditions may not allow for higher speeds, such as when trains are passing through work zones or areas with reduced visibility.

Restricted speed enables trains to react appropriately to obstacles, track conditions, or other emergencies. Operating at this slower speed allows for increased stopping distances and greater awareness of surroundings, which is vital in protecting railway workers and minimizing the risk of accidents. Understanding this definition is essential for railway workers and those involved in train operations, as it directly impacts safety protocols when working near tracks and infrastructure.
