Abstract
The present invention incorporates a caged roller transported along a railroad track by a railroad car adapted for the purpose. The roller is covered with a fluid retaining wear resistant layer which contacts the rail surface. Rolling motion of the roller is generated by movement of the cage along the track and wiping action is caused by retarding rolling motion by contact of the roller with the rear portion of the cage. In a further feature the motion of the roller may be additionally retarded by providing in the interior of the roller a quantity of particulate matter to increase rolling resistance and the weight of the roller.
