I am a novice building an HO gauge set with my son. We are stuck with our layout, which only works when certain switches are set. <br />I have already changed the layout considerably from the first attempt/s, when I didn't understand the polarity issues. <br />Seems that the more we learn the more trouble we get into! <br />If anyone would be kind enough to respond, I can email a BMP or other file type of the layout for comment. <br />
