One of the Strangest Locomotives I've worked on - 1980s Bachmann UP SD40-2

I found this loco in an old box at a hobby store in December of 2019. It was clearly in poor condition but it looked interesting since it had many unusual details, including a blinking led and directional lighting. I don't know what year this engine is from exactly but I would suspect the late 1980s, early 1990s. With a bit of work we got it running like a charm but found several more unusual details.
