A METHOD FOR RELATING TEST TRACK DATA TO THE REAL WORLD

The purpose of this discussion is (a) to develop a method by which test track data can be related directly to any railroad's rock and roll problem, and (b) to provide a means for objectively evaluating the railroad's requirements for 100,000 in-lb to unload the wheels of a high cube car and create a potential derailment condition. The rate of energy buildup on the number of joints required to unload the wheels defines the car's susceptability to derailment. The rate of energy buildup also allows test track data to be related to the real world. By determining the distribution of low joints in the curved territory over which the equipment must operate, and the relative probability of derailment thus generated, the test track data can be used to objectively evaluate the needs of any railroad for rock and roll devices.
