Model motorway for running model cars on uses model cars with direct current motors for using a reducing gear system to apply tension in a car to a wind-up mechanism i.e. as a store of spring power.

摘要

As a model car is driven, a wind-up mechanism uses a reducing gear system to transfer spring power onto a rear drive axle. There is a free-wheeling hub in each rear drive wheel of each car. A model motorway has an electric charging point powered by a mains device for applying tension to a wind-up spring through an electric motor in the model car.
