A toy train is a miniature model of a train designed for children to play with. These trains can be made from various materials, including plastic, wood, and metal. They often come in sets that include tracks, stations, and accessories, allowing children to create their own railway systems. Toy trains can be powered by batteries, wind-up mechanisms, or can be pulled by hand. Many toy trains are inspired by real-life trains, such as those operated by Amtrak or the London Underground. Some popular brands include LEGO, Thomas & Friends, and Brio. Toy trains help develop fine motor skills, creativity, and imaginative play in children.
