What action can a driver take to reset a traction fault?

• A. Increase speed immediately
• B. Move master control handle to coast
• C. Activate emergency brakes
• D. Open the circuit breaker

Answer: (B)

Moving the master control handle to the coast position is an effective action that a driver can take to reset a traction fault because it reduces the load on the traction system. When the control handle is in the coast position, the power to the traction motors is cut off, allowing the system to stabilize. This action can help clear temporary faults that may have occurred due to excessive load or other transient issues in the traction control system. In many traction systems, a fault may trigger protective mechanisms that limit the operation of the train's propulsion system. By moving the control to coast, the driver allows the system to reset and potentially resolve any issues that triggered the fault. After a brief coast period, the driver can then carefully reapply power to the system to see if it operates normally again. This response is aligned with standard operational procedures in train management, focusing on safety and system stabilization.
