I'm really determined to go outside with an "O" gauge layout - about 1250 feet in the back yard. That will extend my train season to 12 months - I'min AZ. I understand garden O is big in Britain, but I can't find much information about it here in the States. I'm afraid to learn by error - which is my normal mode, so I'd like to hook up with some basic info about the tricks of tracks, wiring etc. Does anyone know of any sources?
