Who completes the final rail inspections?

• A. On-Duty Supervisor
• B. Rail Inspector from the State
• C. Independent Auditor
• D. Representative from AAR, the rail carrier

Answer: (D)

Final rail inspections are handled by a representative from AAR, the rail industry group. This person provides an objective, standardized check based on industry-wide criteria, ensuring the carrier’s equipment and procedures meet uniform safety and performance standards. The on-duty supervisor is involved in daily operations, not the formal final verifier. State inspectors oversee regulatory requirements, but the final confirmation of conformance across carriers comes from the industry body, which helps keep inspections consistent. An independent auditor could perform audits in other contexts, but the scenario assigns the final inspection to an AAR representative to maintain uniformity across the network.
