The Westinghouse friction draft gear also is shown in section,with a machine especially designed for testing it in operation. Theavailable power which can be on the draft gear approximates2,000 pounds. A triple valve testing rack is presented to show themanner in which this device is now being installed in many rail-road shops. Sectional parts also are shown of the other apparatusof the Westinghouse Air Brake Company and the Westin
