The first sets, brought out in 1965 by Ideal, were called 'torture tracks', for example, Dearborn Test Track, Alcan Highway Torture Track, etc. There was a variety of cars from the beginning. These were powered by AA batteries. The early cars had the option to free run on a floor, and their wheels could be placed in a variety of positions, allowing for circles, straight line racing, etc. Also, a pin could be installed on any car. This pin would engage the groove that ran down the center of each track.
