Abstract
A hole covering device attached to the sidewall panels or screens in an auto rack car to prevent the direct passage of air and air-carried contaminants into the auto rack car through the multiplicity of holes in the screens to prevent damage to the finishes of newly manufactured vehicles being transported. The hole covering device includes a non-opaque plastic covering panel which is sized and adapted to be mounted on the interior surface of the screen by a plurality of button fasteners to cover a significant number of the holes in the screen. The covering panel permits light into the car through the covering panel and does not significantly inhibit the ventilation of the vehicle exhaust gases during loading and unloading of the vehicles.
