What are some ideas for Lionel track layouts?

According to the website Trainz.com, Lionel model railroad track layouts fall into five basic types known as Loop, Point-to-Point, Loop-to-Loop, Out and Back, and Point to Loop. More advanced small layouts are Double Loop, Twice Around, Double-Back, Phone Booth Terminal, and Savannah Terminal.

The Trainz.com website recommends planning any model railroad layout before building it by creating a drawing on paper or on a computer. A plan ensures that the builder has the track pieces he or she needs, that all buildings, fixtures and accessories will fit within the layout, and that the layout will fit in the space allotted for it.
