Gentlemen , One more time I viewed a video regarding setting points and ligths/signals on the railmaster track plan and it was mentioned that the lights /signals would stop locomotives, even though there was no decoder or actual lights/signals wired to railmaster. My query was if this true how does it stop the locomotivesas I could no see how. Just to me clear I do have a decoder controlling my points. Norman Q 4 to answer your question"Aussie Explanation " was a joke.
