Why is restricted speed crucial when working on non-controlled track?

The importance of restricted speed when working on non-controlled track primarily lies in ensuring that trains can stop in time to prevent accidents. Non-controlled track refers to areas where the usual signal protection and control measures may not be in place, increasing the risk of encountering workers or other hazards unexpectedly.

When trains travel at restricted speeds, it allows the engineer to react more quickly to any unforeseen situations that may arise, whether it's a worker on the tracks or equipment that has not been moved. If a train is moving slowly, it has a greater stopping distance that can be achieved in order to avoid collisions or accidents, thereby significantly enhancing the safety of roadway workers who are on or near the tracks.

This approach is a key safety measure within the Roadway Worker Protection Program, as it prioritizes the safety of workers over the efficiency of train schedules. Other factors like visibility and accommodating unforeseen circumstances do play a role in overall safety, but the primary focus of restricted speed is to enhance the stopping capability of trains in potentially hazardous environments.
