A train set is a collection of miniature trains, tracks, and accessories designed for play or display. These sets can vary in size and complexity, ranging from simple loops of track to elaborate layouts with multiple trains, buildings, and landscapes. They are often made from materials like plastic, wood, or metal and can be powered by electricity or batteries. Train sets are popular among children and hobbyists alike. They encourage creativity and fine motor skills as users build and customize their layouts. Many enthusiasts also enjoy collecting different types of trains, such as steam locomotives or diesel engines, to enhance their collections.
