INVESTIGATION OF A TORSIONALLY FLEXIBLE FREIGHT CAR

With the introduction of a new design wood chip gondola car on the Seaboard Coast Line Railroad, problems arose which defied attempts at solutions by analytical methods and laboratory testing. To positively identify the source of these problems and at the same time analyze the effects of rigidizing the car body, Seaboard Coast Line in a joint effort with Pullman-Standard conducted tests in the actual operating environment of a car. The results of these tests, which are herein discussed, led to the conclusion that "truck hunting" action on the empty car was the primary source of structural problems. The test results are presented in graph form followed by a discussion and conclusions. A summary of the ongoing efforts to determine the most economical solution to the problem is also presented.
