A toy vehicle booster for accelerating a toy vehicle upon a trackway includes a pair of rotating flexible resilient booster wheels positioned on each side of the trackway. In an alternative embodiment, a booster wheel is positioned above the trackway so as to engage the horizontal surfaces such as the roof of the toy vehicles. The booster wheels are formed of a concave resilient structure having a plurality of apertures positioned within the booster wheel to provide a desired flexibility in certain portions of the booster wheel. |
