Abstract
A fragmentable insert for maintaining a railroad draft gear in a shortened state to facilitate assembly in the pocket of a railroad car. The insert is a generally rectangular structure having at least one set of opposing faces bisected by a pair of grooved notches. The two sets of grooved notches are generally perpendicular to each other. A bore extends through the body of the insert between the opposing faces which are bisected by the grooved notches. The bore is configured to reduce the thickness of the material between its wall surface and the surfaces of the other pairs of opposing faces not intersected by the bore.
