Not that there seems to be much interest in startup/shutdown sounds, but here are two videos that play the excellent startup and shutdown sounds of my MTH Premier New York Central GP9 #6001 diesel locomotive with PS-3. They’re shaky because I have to hold the camera and start/stop the video with one hand while operating the transformer throttle with the other. The GP9s were powered by an EMD 567C engine that produced 1750 horsepower.
