Model railroad track scrubbing car

A track scrubbing car for an electric model railroad having straight and curved track joined together to form a layout for an electric locomotive to propel a train along the layout, the track having at least two spaced apart outer rails, each rail having a narrow width, the locomotive having at least one set of two spaced apart wheels, the outer rails supportingly engaging and guiding the wheels as the locomotive moves the train along the layout, the outer rails forming a portion of an electric circuit that supplies electric power to the locomotive via conductive engagement with its wheels, said track scrubbing car comprising:

• a chassis having front and rear ends and longitudinal and normal axes, said chassis including a front wheel assembly secured proximal said front end and a rear wheel assembly secured proximal said rear end, each wheel assembly being pivotally secured to said chassis and including at least one set of spaced apart car wheels, said track scrubbing car having a desired car weight, and said car wheels being adapted for weight supporting engagement with the outer rails and movement along the track rails via the locomotive;
• a first cleaning assembly having a first roller mount and a first roller, said first roller mount being secured to said chassis and forming a substantially horizontal first roller axle to rotatably support said first roller under said chassis, said first roller axle being at a first scrub angle relative to said normal axis of said chassis, said first roller having a first roller diameter and a generally cylindrical shape with an outer surface, said first roller including a tubular roll made of a compressible and resilient material;
• a second cleaning assembly having a second mount and a second roller, said second mount being secured to said chassis and forming a substantially horizontal second roller axle to rotatably support said second roller under said chassis, said second roller axle being at a second scrub angle relative to said normal axis of said chassis, said second roller including a tubular roll made of a compressible and resilient material;
• each said mount being adapted to firmly position its said roller axle at a height of less than half its said roller diameter above the track rails, said first roller compressively engaging at least the first rail and said second roller compressively engaging at least the second rail while maintaining said weight supporting engagement between said car wheels and the track rails, said compressed engagement forming an active working surface on each roller, said active working surface deforming around the top and engaging the side of its respective at least one rail;
• and,
• wherein the movement of said track scrubbing car along the track rails provides across-the-rail scrubbing action between said rollers and the rails and simultaneous rotation of said rollers about their said axle, each said roller having at least one circumferential working area resulting from said rotation of said roller along its at least one rail, and each said circumferential working area have a working width greater than the narrow width of its respective rail when moving along the straight track.
