ABSTRACT:
A railway car with a slackless drawbar arrangement for unit trainservice and the like is provided and includes a drawbar having a section which is fabricated. The fabricated intermediate section is cut from a section of seamless pipe or tubing or can be fabricated from plate, while the coupling end pieces attached to each end of the shank are cast members made from typical casting methods. The coupling end pieces can be cast into standard fixed or rotatable drawbar ends or even be a combination thereof with rotational capability. The geometric shape of the intermediate section is varied, depending upon the application, so that resistance to torsional or bending loads is maximized. The fabricated shank portion is hollow, as well as part of the body of the coupling end pieces, thereby reducing the railcar's weight and costs to manufacture.
