Thanks, Jon. That’s precisely what I’m talking about. I use .015" or thereabouts piano wire. Bend it into a “V” shape, and bend the ends downward. On the switch, move the points into the middle, where neither point is in contact with the stock rail. Drill two holes down the center of the track, one in the throwbar, and one in the adjacent tie. Make sure the width of the V is greater than the distance between the two holes. Insert the bent-down ends of the V spring into the two holes. The spring tension will hold the points against the stock rail, but a train can still push the points over the opposite way if need be. They’ll then stay in that position. It’s great for reverse loops where you want to alternate which way you go around the loop each time. It never ceases to amaze me when people come to see the railroad and see the trains running opposite ways around the loop each time, and ask me “how do you get them to do that?” It’s a very low-tech solution that makes “running in circles” interesting.
Later,
