After placing the generator field switch in the OFF position, what should the engineer do next in the engine shut down process?

• A. Remove reverser
• B. Release air brake
• C. Close battery switch
• D. Check oil pressure

Answer: (A)

Opening the shutdown sequence, turning off the generator field switches off excitation to the traction motors, so the locomotive no longer wants to move under electrical power. The next step is to remove the reverser and put the control in neutral. This isolates the traction control circuit and prevents any inadvertent re-energizing of the propulsion system or movement, ensuring the locomotive is truly in a safe, non-operational state before proceeding with other securement tasks. Releasing the air brakes or closing the battery switch are important actions in different parts of procedures, and they serve security and power-management roles, but they aren’t the immediate action that directly secures propulsion after the field is de-energized. Checking oil pressure is a diagnostic step, not part of the immediate securement sequence.
