Abstract:
A method of re-railing a de-railed railroad car which has been de-railed from rails, comprising the steps of:A) positioning in front of the de-railed railroad car a re-railing unit comprising: (i) a base having longitudinally spaced ends, (ii) a support plate mounted on the base for longitudinal sliding movement thereon, (iii) a lifting mechanism mounted on the support plate, (iv) a lifting arm suspended at its upper end from the lifting mechanism and being raisable by the lifting mechanism, the lifting arm having an engagement structure, and (v) a sliding mechanism for sliding the support plate longitudinally across said base; B) removing a knuckle from a body of a coupler of the de-railed railroad car by removing from upper and lower spaced-apart flanges of the body a pivot pin which pivotably connects the knuckle to the body; C) inserting into the body an adapter member in a generally horizontal direction and connecting the adapter member to the body by inserting a pivot pin through the body and upper and lower flanges and through an ear of the adapter member which is positioned between the upper and lower flanges, the adapter member being engageable by the engagement structure; D) actuating the sliding mechanism to position the lifting arm adjacent the adapter member; E) actuating the lifting mechanism to raise the lifting arm such that the engagement structure engages the adapter and raises the railroad car; F) actuating the sliding mechanism to position de-railed wheels of the railroad car over the rails from which they are de-railed; and G) actuating the lifting mechanism to lower the wheels onto the rails.
