Well, you make it sound silly, when you put it that way.
I can try and make a long story, shorter.
First the earth cooled, then the rains came. Then I purchased an PS3 F40PH that had been upgraded to PS3 and tried swapping the sound files, and there was a short that ended up frying the board (when I messed with it) and yes, I’m back to a PS3 upgraded locomotive that now has the sound file I wanted (Lake Shore) but the stock strobe rate.
Whew.
