A skid arrangement to protect an appurtenance which extends from the bottom of a railroad tank car. The skid arrangement includes a ramped box-like frame structure which is defined by longitudinal side plates and transverse end plates and diaphragm plates. The upper edges of the end plates and diaphragm plates are welded to a reinforcing pad. A pair of wood blocks are positioned within and secured to the frame structure in contact with the reinforcing pad by stud members extending therethrough and through the side plates. Impact forces which are applied to the skid arrangement are directed by the stud members into the wood blocks and in turn are directed into the reinforcing pad and uniformly distributed over a substantial length of the body of the tank car.

In a railway tank car having an appurtenance extending downwardly from a generally annular body portion thereof, an improved skid arrangement; comprising: (a) a reinforcing plate means secured to the underside of said body portion extending longitudinally on either side of said appurtenance; (b) a skid frame structure suspended from said reinforcing plate means in a surrounding relationship to said appurtenance, said skid frame structure defined by a pair of longitudinally extending side plates having vertical extents which decrease as said side plates extend longitudinally outward from said skid frame structure so as to define a ramped lower surface and a pair of transversely extending end plates extending between and secured to the outer ends of said side plates so as to define a box-type structure surrounding said appurtenance, said side plates having upper edges transversely spaced outwardly of said reinforcing plate means, said end plates being rigidly secured to said reinforcing plate means such that said upper edges of said side plates and the upper edges of said end plates are spaced a short distance from said body portion; and (c) a lightweight filler means having a high compressive strength secured within the confines of said skid frame structure, said filler means having an upper surface which is positioned in contact with said reinforcing plate means so as to transmit impact forces applied to said skid arrangement uniformly to said reinforcing plate means and into said body portion.
