I remember vaguely such an article by Linn Westcott in Model Railroader
magazine about 1961. I realize this is not the article you recall, but read on.
He used British levers to control a custom-designed interlocking plant. It was
not a true armstrong design, since he used electrical contacts to power relays
to make things move. He built it first in wood to test it, then in brass.
It worked a lift bridge and signals and a derail. Six or eight levers were
required to make it all work. There was a track diagram above the levers with
lights. The mechanism below had a plexiglas front, so you could see the bars
moving up and down and left and right.
The above is from memory, which after fifty years, is not perfect. I kept the
article for many years until I realized that I would never get around to
designing and building my own. Check it out.
