What should you verify during a Daily Inspection of a lead locomotive?

During a Daily Inspection of a lead locomotive, it is essential to verify the functionality of all critical systems. This includes checking the air brake system, engine systems, and safety devices, among other components. By ensuring that all critical systems are functioning properly, potential issues can be identified and addressed before they lead to safety risks or operational failures.

Focusing solely on the engine oil level would neglect the many other vital systems that need to be inspected to ensure safe operation. Similarly, while the cleanliness of the exterior can contribute to maintenance and operational efficiency, it does not impact the immediate safety and functionality of the locomotive. Lastly, only checking the brake mechanisms ignores other critical systems, which could lead to hazardous situations if they are not adequately assessed. Thus, verifying the functionality of all critical systems is crucial for comprehensive safety and operational readiness.
