LONGITUDINAL-SHOCK PROBLEMS IN FREIGHT-TRAIN OPERATION

Violent shock during train "run-in" and "run-out" is a familiar problem of freight-train operation. Draftgear characteristics necessary for smooth train running are shown theoretically, the influence of car geometry being included. Instrumented run-in and run-out tests with a short train followed by running tests with 70 car trains confirmed the theory and showed that shock-free freight trains are possible. The application to current practice is discussed.
