What effect will pressing the Emergency Fuel Cutoff switch have on the locomotive?

• A. Cuts Power To Traction Motors
• B. Increases Throttle
• C. Activates Engine Starter
• D. Stops The Flow Of Fuel To The Engine, Resulting In Engine Shutdown In The Engine Where The Button Was Pressed

Answer: (D)

Emergency Fuel Cutoff works by stopping fuel flow to the diesel engine. Pressing it immediately halts fuel delivery to the engine, causing it to shut down in the engine where the button was pressed. Once the engine stops, the generator stops producing electrical power, so the traction motors lose power and the locomotive stops. It isn’t about increasing throttle or starting the engine—it’s a rapid shutdown of the engine.
