Clean your track as you run your trains with this unit! This is for DCC only and uses track power, so there is no battery to replace.
It can be hooked to the headlight function so that it is not on all the time.
The cleaning module comes with a nine volt regulator and a schematic wiring suggestion.
It works well in an Athearn Genesis B powered unit with a small decoder other than the light board replacement.
An ESU LokSound Micro could be used for sound. If you have enough room, a cab unit could be used.
It works best if one axle can be electrically separated for the cleaning circuit.
This does take some skill to install. Litchfield Station will install it at no additional labor charge when installing a decoder.
