SHOCK AND VIBRATION ON RAILROAD MOVEMENT OF FREIGHT

One of the more pressing problems concerning rail movement of freight is the cost of securing lading to the car and protecting it properly from impact shock. The highway truck has an advantage in this regard because friction between rubber tires and pavement govern the maximum longitudinal forces developed, except for dock impacts. Rail, however, has the advantage in vertical and lateral shock and vibration control and, with proper design and operation, can meet the truck's longitudinal conditions. Adverse criticism has been received by the railroads because of their past reluctance to take the necessary steps to reduce lading damage. We now have the hardware to provide this protection, and the rail industry as a whole is rapidly applying it to its more critical loads. The purpose of this paper is to acquaint the shipper with the railroad environment and with the characteristics of the equipment available for controlling it.
