A model railway is a miniature representation of a railway system, often built for hobbyist enjoyment. It typically includes scaled-down versions of trains, tracks, and landscapes, allowing enthusiasts to create realistic scenes. Model railways can vary in size, from small tabletop setups to expansive layouts that occupy entire rooms. Hobbyists often use various materials to construct their model railways, including plastic, wood, and metal. They may also incorporate features like scenery, buildings, and figures to enhance realism. Many enthusiasts join clubs or attend exhibitions to share their passion and showcase their creations.
