When are conductors required to perform train inspections?

Conductors are required to perform train inspections at an industry prior to moving cars because this ensures that all equipment is safe and in proper working order before any movement occurs. Conducting these inspections helps identify potential issues that could compromise safety during transit, allowing for necessary maintenance or repairs to be addressed before the train departs.

This practice is essential to maintaining safety standards and compliance with regulations, and it ensures the integrity of both the train and the cargo being transported. Inspections prior to moving cars at an industrial site also allow for better communication among crew members regarding the condition of the equipment being handled, which is crucial in a high-traffic or operational environment.

In contrast, the other scenarios provided do not align with standard operating procedures mandated for conductors, which is why they are not the correct contexts for requiring inspections.
