They come in all shapes and sizes, from small ones that fit in the palm of your hand to large ones that wind around an entire room. Some people even collect them and display them proudly on shelves or in glass cases. Toy trains are more than just a fun toy - they're also educational tools that can teach kids about science, math, and engineering concepts like friction, gravity, and momentum.
