A long time ago there was a post, I believe in this forum about making a box with DPST switch. When the switch was thrown one way it would cut power to the main line and power up a two pieces of track to program an engine to the hand held control. when the switch was thrown in the other direction the main line would power up and the programming track would be without power. I believe there was a diagram showing how to make same. If anyone knows or remenbers this post or can come up with one please respond. Thank You!!!
