摘要： A racing game to be played with at least two vehicles which are driven at substantially the same speed wherein a track is arranged to establish a raceway including at least a first course and a second course, with the second course being longer than the first course such that the elapsed time to travel the second course with the vehicles traveling at substantially the same speed is longer than the elapsed time to travel the first course. The raceway includes at least two crossover means on the track which are arranged to be manually controlled by the players of the game such that the vehicles travelling along the first and second courses at substantially the same speed may be switched to and from the longer and shorter of the courses under the control of the players whereby, notwithstanding the constant speed limitation of the respective vehicles, it is possible to cause one of the vehicles to traverse the raceway, or one or more turns about the raceway, in the shorter elapsed time than the other player-controlled vehicle.

摘要： A miniature four-wheeled vehicle is provided with a solenoid having a linearly movable armature for turning the steering wheels in response to electrical impulses received by a set of contact brushes on the vehicle which selectively engages the conductive track system on a supporting surface which also supplies power to the vehicle and includes conductive guiding areas on the surface for steering the vehicle through a switch in the track system.
