We sold our house back in 2022 and bought an appartment. The layout room is only 3x3,5 m (10'x11 ' 4''). Big enouth to build a small switching layout with interesting operations.
The section with lumber yard, stock yard and transfer yard can be folded down to make it easier to get into the room.
The section with red lines is not used during operations. It's only used when I would like to run trains around the layout.
