Ralph's layout started with some N-trak modules and some other fill in pieces.  The current layout is two levels that fills a good portion of his basement.  One of the highlights on the layout are two triple track helixes that are on opposite ends of the layout.  These helixes run flawlessly as they get the trains from one level to another.  Ralph's layout is NCE DCC and most of the turnouts are DCC controlled.  Ralph also added a pennisula that models Milwaukee's famous Beer Line.
