I've completed the diagram so that it will work for the SPDT relay case.  Note that the insulated rail is just that, totally insulated from the outside rail.  The coil and the relay arm both connect to track power to light the lights and power the relay.

John, took your advice and studied your diagram in detail and I believe I have it now, so a big thanks.

As was explained, the green light is lit, the engine hits the insulated rail and the red light goes on and the green light turns off.

In the Lionel diagram, why do they show an insulated section to the left of the track with the insulated rail?????  Also, why not on both sides of it then?

QUESTION: what triggers the green light to come back on or is it simply that when the red "connection" is de-energized by default the green 'connection' gets re-energized?

I think my list of questions is done with this post - I hope!  Assuming these 2 are answered that is.

Again, as always, thanks - walt
