What is the first step of shutting down an engine?

• A. Ensure the hand brake is fully applied if leaving the locomotive unattended
• B. Place generator field switch OFF
• C. Remove reverser
• D. Crank engine until it stalls

Answer: (A)

The question tests safety sequencing when shutting down a locomotive. The first step is to secure the locomotive by applying the hand brake fully if you’re leaving it unattended. This is crucial because it prevents any movement that could occur from wind, gradient, or residual energy in the system while you complete shutdown tasks. Securing the train first protects people and equipment on and around the locomotive. Turning off the generator field switch is part of reducing electrical load, but it doesn’t address the immediate risk of a runaway locomotive, so it isn’t the first action. Removing the reverser isn’t a standard first step and could leave the unit in an unsafe or unpredictable state. Cranking the engine until it stalls is dangerous and can cause mechanical damage and injury, so it’s not a proper first step either.
