  • Publication number: 20110250822
    Abstract: A toy race car track can be expanded to an unlimited number of lanes via interlocking side-by-side tracks. The toy race car track may be extended in length by adding additional track segments end-to-end. The tracks of the present invention may be useful for racing a toy race car with four wheels and a compartment for a marble in a central region of the car. With a marble installed in the car, all four wheels and the marble may roll at the same time as the car is moved. The car may be rolled on a surface or raced on the track. In some embodiments, the car may include lights that may flash as the car is moved.
