This simple device is attached to the axle of a vehicle and dragged around the layout by the vehicle. The coarse felt pad attached to the Track Cleaner drags along the track, keeping it clean, when the pad is completely worn and dirty, you can simply unclip it and throw it away. These are sold in packs of five so there are plenty of replacements.
