The rule allowing continued operation after headlight failure to the next calendar day inspection or to the nearest forward location for repairs is found under which USOR section?

• A. USOR 416
• B. USOR 410
• C. USOR 408
• D. USOR 413

Answer: (D)

When a locomotive headlight fails, the rules recognize a temporary allowance: you may continue operation to reach the next calendar day inspection or to the nearest forward location for repairs. This keeps trains moving for essential repairs while still prioritizing safety, visibility, and signaling integrity. The specific rule that covers this headlight-related allowance is USOR 413. It lays out the conditions and the point-to-point limit for continuing movement after a headlight failure, ensuring you end up at a place where the headlight can be repaired promptly. Other USOR sections address different equipment faults and do not describe this particular headlight situation.
