What is a shelf-layout?
When placing a model railway layout on a shelf, the dimensions have to be small in depth. However, a shelf layout can be large in length. It can be designed as an L-shape or U-shape running along the entire wall of a room. Or you build a mini layout to be placed on a small windowsill.
Shelf layout track plans are often based on a point-to-point concept. Model trains run from A to B and back again.
