Eureka! Thanks Ralph,that does seem to be the problem.Now do I need to simplify my layout,or is there a somewhat easy & affordable way for me to make it work the way I have it setup?
royzee,
I'm so smart because I did this once as well!

A couple of questions first.
Have you broken your track plan into any electrical "blocks"? Do you have any experience with that? If not, it refers to isolating sections of track so you can turn power on and off to parts of your layout. It will, for instance, let you park a train on a siding and let another train go by, adding to the fun and prototypical action.
Reverse loops need to be wired as an isolated block and be connected to a double pole, double throw switch that reverses the polarity of your track when your train goes through the loop. I apologise for not being the most electrically inclined forum member, otherwise I'd try to draw you a sketch. If wiring isn't your forte you might consider buying Atlas' book on model railroad wiring that features the use of their easy to hook up components. I use them.
There are other fine books about wiring at your hobby store that feature regular electrical switches.
Your other alternative is to reconfigure the track in a way that does not create a return loop.
Best wishes!
Ralph
