When should the Automatic Coupler fault be addressed during the safety loop process?

• A. When the Master key is engaged
• B. After ensuring the Deadman's device is set correctly
• C. After uncoupling the train
• D. When the trip loop light is illuminated

Answer: (C)

Addressing the Automatic Coupler fault after uncoupling the train is essential because, at this point, the system is in a stable state where the dynamics of the train’s operation are minimized. The uncoupling process removes the direct interaction between trains, allowing technicians to focus specifically on diagnosing the fault without the concern of movement or coupling-related hazards. In this state, maintaining safety is paramount, and by waiting until the trains are uncoupled, any risks associated with accidental coupling or train movement are mitigated. This cautious approach ensures that any repairs or inspections can be performed safely, without the influence of additional operational variables. The importance of ensuring a stable environment before diagnosing faults cannot be overstated, as it directly correlates to the safety of personnel and the proper maintenance of train systems.
