Model railroad layout

In model railroading, a layout is a diorama containing scale track for operating trains. The size of a layout varies, from small shelf-top designs to ones that fill entire rooms, basements, or whole buildings.

Attention to modeling details such as structures and scenery is common. Simple layouts are generally situated on a table, although other methods are used, including doors. More permanent construction methods involve attaching benchwork framing to the walls of the room or building in which the layout is situated.
