Thanks, Stan. Much appreciated. And thanks for the tip on the type of switch.
I guess what I'm looking for (as mentioned above ) is a simple wiring diagram that I can follow. The UCS section has 4 posts and these DPDT switches (if I'm reading it right) have 6 posts/terminals. So I'm looking for a clear picture on which wires go where. The one diagram in the linked thread is for Fastrak; not sure if that's the same set up as a Lionel classic UCS. Also, I don't need uncoupling so assume that changes the wiring.
