What safety measures are associated with clearance points on a railroad?

Clearance points are specific locations on a railroad that ensure the safety of personnel and equipment by allowing safe passage beside passing trains or cars. The purpose of these points is to provide areas where individuals can stand safely while observing train operations. This is particularly important in areas where trains might pass closely to people or equipment, as it helps to prevent accidents and injuries.

In situations where clearance points are established, guidelines usually state how close workers can be to moving trains, ensuring they have a designated space where they can stand without risk. Fostering this environment promotes safety practices that align with railroad operating procedures.

The other options do not accurately describe the intended function of clearance points. While they may touch upon different aspects of rail operations, they do not align with the critical safety purpose that clearance points serve.
