The invention is a model railroad track scrubbing car with rollers set at a scrub angle of about 30° to scrubs the tops and sides of the track rails. The rollers freely rotate about fixed axels under the chassis of the weighted car. Each roller is preferably a conventional paint roller with an inner sleeve and an outer tubular roll made of an absorbent, compressible, resilient foam material. The active working surfaces of each roller compress against, frictionally engage and deform around the tops and sides of the rails. The scrub angle and rollers provide across-the-rail scrubbing action and possibly along-the-rail scrubbing action. The circumferential working areas of the rollers are wider than the width of their associated track rails. The scrub angle and height of the roller axels above the track rails are adjustable to set the amount of roller compression and scrubbing action against the track rails.
