Abstract
A lightweight and topless draft arm is disclosed for use in a railway car. The draft arm includes an open top surface with the metal layer removed, lateral support members and tiebars transversing the side walls for greater draft arm strength, and thinner side walls below the keyslots. Removal of the top surface of the draft arm eliminates the traditional double layer of material formed by the bottom of the car body and the top of the draft arm. Effectively, the bottom of the car body becomes the top of the draft arm resulting in a lighter weight railway car.
