Alright, I'm new at this and I have a problem with my O-gauge layout that I can't figure out. I have a basic oval layout, with 2 switches that connect a seperate siding on that same track to park a train. I have an engine on the other siding as well. I want to be able to run both of them but at seperate times, and from the same transformer. I have a 3-way switch which I used a LONg time ago on this layout, however I CAN'T remember how to wire it up to make it work. Any help from anyone would be greatly appreciated, help on how to wire it up correctly, or how to wire the layout so that it works. Thank you! Merry Christmas!
