What I would like is a wheel cleaner accessory that actually cleans the wheels and rollers as the train moves by. This is one for HO.
The crude on the tracks starts on the wheels.
Making a box to house a set of rails with a motor or motors set transverse that have rotating brushes facing the two sides of each wheel and the underside of the wheel. As a train moves over the rails past the set of rotating brushes each wheel is cleaned. The wheel cleaning box would be placed a bit lower than the track and attach to the track at each end.
That's usually as far I get.
