How long are locomotive daily inspection cards considered valid?

The validity of locomotive daily inspection cards is set to one day. This is because daily inspections are crucial for ensuring the safety and operational readiness of the locomotive. Conducting these inspections on a daily basis helps identify any potential issues or maintenance needs that could affect performance and safety during operations.

Each day's inspection is performed to check various components, including brakes, lights, and mechanical systems. Since conditions can change rapidly—such as wear and tear or unexpected mechanical failure—it is vital that inspections are treated as a fresh assessment each day. Ensuring that the inspection card is valid for only one day emphasizes the importance of routine safety practices in railway operations. Regular daily checks help maintain the integrity of the locomotive equipment and ensure compliance with safety regulations, thus safeguarding both the crew and passengers.
