Abstract

Abstract A toy track system which comprises a wheeled and powered toy vehicle and a closed track on which the vehicle is adapted to travel. The track has a bridge incorporated therein which includes racks engageable by gears which are provided on a shaft operatively connected to a motor of the vehicle, said shaft being rotatably carried by the vehicle, separately from wheel axles thereof. When the vehicle travels on a level surface, it is driven by its wheels, and, when it crosses the bridge, it runs with the gears engaging said racks. The vehicle runs on the track while moving a funnel up and down.
