An electronic automatic dual track cleaner for use with all types of Analogue (12v DC) controllers. This cleaner can be used with a dual controller or two separate controllers. The unit superimposes a harmless high frequency signal over the output from the controller. When a poor contact between loco and rail is detected the unit switches on, ionising the gap and burning off the dirt, switching off again when contact is restored. Please note that if you are using power clips or power track fitted with RI suppressors then these suppressors must be removed for the track cleaner to work correctly.
