ABSTRACT:
A toy vehicle track with toy vehicles having an electric drive motor disposed in the chassis thereof. The track is formed of segments which are connected by plugging together. The electric drive motor in the vehicles is supplied with electricity via collectors and conductors placed in the track for uninterrupted operation over a period of time. When electrical connection with a net fails or is terminated, the vehicles can be operated over a further preset length of time. The segments are removably or fixedly connected with conductors along the entire track. The vehicles have collectors in contact with the conductors and a chargeable power source serving as an electric buffer. The power source and the collectors are simultaneously in permanent connection with the drive motor. If the power supply is cut off from the electric net, the internal power source is automatically activated, and permits further operation until discharged. The conductors on the segments are formed by metal foil or metal foil segments, by electrically conductive formed parts clampingly clipped to the individual segments, which are either removably clippable to the edge members or on the segments in the area of the track surfaces, or they are irremovably fixed with the segments.
