Does anyone know where I can get one of those track sweepers I’ve seen around? It’s like a bottle brush mounted in a frame and driven by a belt and small motor. I’ve seen them pre-mounted on cars and also in a kit that can be mounted on an engine or car. I’d like to put one on the front of my LGB track cleaning engine. Speaking of which, I need the cleaning wheels (the removable discs) for it too. Does anyone have a set for sale?
