Abstract: A wear liner for use in a railroad freight car between a truck bolster bowl and a car body center plate comprises a non-metallic wear liner bowl which has a horizontal bottom floor, and an upstanding circumferential side wall extending upwardly from the periphery of the bottom floor to a top flange which forms an upper rim. A sealing member extends outwardly from the upper rim and has an upper lip which extends outwardly and upwardly to contact a base shoulder of the center plate. The sealing member also has a lower lip that extends outwardly and downwardly to contact a top shoulder of the truck bolster bowl. The floor and circumferential side wall of the wear liner are made of a harder synthetic resin plastic material than the synthetic resin plastic material of which the softer sealing member is made. The composite sealing member lips are outboard of the side wall of the car body center plate and the truck bolster bowl so as to be out of the way when the center plate is being lowered into the truck bowl.

Abstract: An improved adapter assembly for use in a railcar truck where an axle and bearing are loosely journaled in the pedestal area of a side frame, the adapter assembly being mounted above the bearing in the pedestal opening and including an adapter plate which is mounted on the top of the adapter, the adapter together with the bearing and axle being capable of lateral movement relative to the side frame.

Abstract: In a railroad auto rack car having an array of side panels with horizontal air gaps between vertically adjacent panels, a strip of continuous flexible resilient plastic material, preferably vinyl having a white color, is fitted onto and adhesively secured to horizontal flanges of vertically adjacent upper and lower side panels to function both as a seal to close the horizontal air gap against swirling road dirt and also as a protective bumper to protect the automobiles from damage from being bumped during loading and unloading of the rack car. The bumper seal in preferred form has upper and lower legs each having a channel which faces the center axis of the bumper for receiving the vertical flanges found along the horizontal edges of the side panels of the rack car. The portion of the bumper seal along the center axis is designed to provide a spring action to accommodate for variations in the width of the air gaps.
