Thanks Brian for taking so much time to provide a substantial and informative response. What a great fraternity there is amongst model rail modellers. I'm far better off with acquiring essential knowledge on constructing a layout than I was a mere few days ago, and the contributions to date have vastly improved my state of mind.
Now that Point Motors & a CDU have been identified for me, I shall have to wait until the next pay-day before going after the best switches to work with my project.
Don't let that idea delay other members' contributing though, I shall always be reading/replying to responses.
