LONGITUDINAL SHOCK AND VIBRATION

All longitudinal shock involves impact between two cars, and generally the cars are either traveling in the same direction or one is standing. For most commodities, impacts at speeds of less than 5 mph, even with standard draft gear, do not contribute to damage. The railroad yard is the source of most impact damage, whether the cars are flat switched, or sorted by modern gravity systems. Use of long travel shock absorbers can do much to reduce shock forces. Again we must stress the importance of low speed switching and good loading practices. Railroads must continually police their systems to maintain switching speeds of less than 6 mph.
