From the leaders in track cleaning comes the new N scale version of the Lux Modellbau polishing and cleaning car. A miniature high-quality motor powers a cleaning wheel that cleans and buffs the tops of your rails for the best electric contact. Felt cleaning wheels are included. Abrasive wheels can be ordered separately and easily swapped. This new version comes with SSF-09 auto-on/off electronics for DCC and analog railways - the motor starts when the car begins moving (pulled by a locomotive) and shuts off when the car stops, even on digital systems with constant DCC power on the track.
