Which of the following conditions is NOT required to be checked during a freight car safety inspection?

During a freight car safety inspection, it is essential to assess various components to ensure the safety and functionality of the railcar. Among the conditions that must be inspected, leaning of the car, objects hanging from the car, and overheated wheels are all critical checks. These issues can directly impact the stability and safety of the car as it travels on the rails.

Leaning of the car indicates an imbalance or structural issue that could lead to derailment. Objects hanging from the car pose a hazard both to the car's operation and to other trains or equipment on the tracks. Overheated wheels can signal potential brake problems or excessive friction, which could cause significant operational risks.

However, checking for electrical faults is not typically a requirement during a standard freight car safety inspection. Specific electrical systems may have their own maintenance schedules and testing protocols, but the foundational safety checks usually focus more on the car's mechanical and physical integrity rather than electrical conditions. This distinction clarifies why electrical faults are not included in the basic safety inspection parameters for freight cars.
