Hi Rich - After looking over the links you supplied, I may have narrowed down the article. I know now it must have been in MR as they always would list Radio Shack parts where possible. The throttle was constructed using a small metal box and had a transistor mounter on the outside of the box with a heat sink. It may have been in one of these three articles:
Easy to Build Electronic Throttle, December 1986
Electronic Symposium: Easy to Build Throttle, May, 1987
Build an Inexpensive Walkaround Throttle, January 1986
Thanks!

This was an era for a lot of DIY electronics articles. I built several memory walk around throttles for our train club about that time from a Model Railroader Article. This one featured the actual throttle unit under the layout and hand held controllers that could be unplugged and moved to another outlet without stopping the train. Some of them were removed to put in DCC and they promptly came home with me and are under my layout.
Here are some possibilities.

I might have the magazine but I need a more accurate month/year/

If you ever fall over in public, pick yourself up and say “sorry it’s been a while since I inhabited a body.” And just walk away.
Hello! I am trying to locate an article that appeared sometime in the eighties about building a handheld throttle using items from Radio Shack. It was a simple tethered throttle with a transistor, speed control, reversing switch, and, I think, a resistor or two. The article was either in MR or RMC. I've searched the article database but can't tell just from the title which one I'm looking for.
I was hoping someone might know the article title from my description.
