ABSTRACT:
A light weight draft arm is provided for use in a railway car. The draft arm includes a center plate with a significant amount of material removed and lateral support members inboard and outboard of the center plate transversing the side walls. Removal of the material around the center plate along with the addition of the lateral support members decreases the overall weight of the draft arm while still maintaining its strength. With the exception of the enhancements around the center plate, the draft arm is conventional.
