The Westinghouse friction draft gear also is shown in section,with a machine specially made for testing it in operation. Theavailable power which can be e.xerted on the draft gear approximates2,000 pounds. A triple valve testing rack is presented to show themanner in which this device is now getting installed in a lot of rail-road shops. Sectional parts also are shown of the other apparatusof the Westinghouse Air Brake Organization and the WestinghouseTraction Brake
