Train tracks
Many toy train tracks are made out of wood, which is typically safe as long as they don't have sharp edges. Some are made with rubber, but they are less common. If you are referring to the electric train sets for kids (and adults), they use metal tracks that connect together and power the trains through its metal wheels. Non-electric toy trains may have wood, plastic, or rubber tracks.
Railroad tracks are often called rails.
You don't tie people to the train tracks. You can hogtie them and put them on the train tracks though.
You can acquire a cannon for your train on Spirit tracks.

Railroad tracks are made from steel.
