Abstract: A door edge protection assembly for installation on a railcar. The railcar has a side wall, a roof rail running substantially horizontally along the top of the side wall, a roof extending upwardly and inwardly from the roof rail, and a plurality of decks for supporting vehicles thereon. The door edge protection assembly includes a door edge protection member for cushioning impacts between a vehicle door edge and at least one of the side wall, the roof rail, and the roof. In the preferred embodiment, the door edge protection assembly also includes a clip for supporting the deformable door edge protection member in the interior of the railcar. The clip lockingly engages the roof to provide positional stability of the deformable door edge protection member relative to the roof rail and roof.

Abstract: A heat exchanger is formed by a pair of tank units with a core therebetween. The core comprises a plurality of tube passes extending between and in fluid communication with the tank units, and air centers connected between the tube passes in conductive heat transfer with air and the flow passes. The tank units are formed by separate tanks and headers. The tanks and headers include a flat, coplanar perimeter flange extending thereabout. The flanges include locking members therethrough to secure the header to the tank. The locking members may comprise longitudinal projections formed through the tank flange projecting through the header flanges, or alternatively aligned apertures in the flanges with plug inserted therethrough.
